1Note: this file lists major user-visible changes only. 2 3* Changes in Quagga [] 4 5- [zebra] "no link-detect" is no longer the default. 6 7 The previous release of Quagga always explicitly writes-out the 8 link-detect configuration state. Therefore, to retain current behavior 9 save your config with the prior release before updating. 10 11 Otherwise, review your configuration. Note, most users will generally 12 want to have link-detect enabled, and so can just remove 'no 13 link-detect' from their interface configuration. 14 15 This release also adds a global configuration to specify the default, 16 which can be specified in the zebra configuration as: 17 18 default link-detect (on|off) 19 20 This will then apply to any interface which does not have link-detect 21 explicitly configured. 22 23* Changes in Quagga 0.99.24 24 25User-visible changes: 26- [pimd] New daemon: pimd provides IPv4 PIM-SSM multicast routing. 27- [bgpd] New feature: "next-hop-self all" to override nexthop on iBGP route 28 reflector setups. 29- [bgpd] route-maps have a new action "set ipv6 next-hop peer-address" 30- [bgpd] route-maps have a new action "set as-path prepend last-as" 31- [bgpd] Update validity checking (particularly MP-BGP / IPv6 routes) was 32 touched up significantly. Please report possible bugs. 33- [ripd] New feature: RIP for IPv4 now supports equal-cost multipath (ECMP) 34- [zebra] Multicast RIB support has been extended. It still is IPv4 only. 35- [zebra] "no link-detect" is now printed in configurations since it won't 36 be the default anymore soon. To retain current behaviour, re-save your 37 configuration after updating to 0.99.24. 38 39Distributor-visible changes: 40- --enable-pimd is added to enable pimd. It is considered experimental, though 41 unless the distribution target is embedded systems with little flash, there 42 is no reason to not include it in packages. 43- --disable-ipv6 no longer exists as an option. It's 2015, your C library 44 really needs to have IPv6 support by now. 45- --disable-netlink no longer exists as an option. It didn't work anyway. 46- --disable-solaris no longer exists as an option. It only controlled some 47 init scripts. 48- --enable-isisd is now the default. 49- mrlg.cgi is no longer included (it was severely outdated). It can be found 50 independently at http://mrlg.op-sec.us/ 51- build on Linux with the musl C library should now work 52 53* Changes in Quagga 0.99.23 54 55Known issues: 56- [bgpd] setting an extcommunity in a route map on a route that already has 57 an extcommunity attribute will cause bgpd to crash. This issue will be 58 fixed in a followup minor release. 59 60User-visible changes: 61- [lib] Performance enhancements on hashes and timers. 62- [bgpd] New feature: iBGP TTL security. 63- [bgpd] New feature: relaxed bestpath criteria for multipath and improved 64 display of multipath routes in "show ip bgp". Scripts parsing this output 65 may need to be updated. 66- [bgpd] Multiprotocol peerings over IPv6 now try to find a more appropriate 67 IPv4 nexthop by looking at the interface. 68- [ospf6d] A large amount of changes has been merged for ospf6d. Careful 69 evaluation prior to deployment is recommended. 70- [zebra] Recursive route support has been overhauled. Scripts parsing 71 "show ip route" output may need adaptation. 72- [zebra] IPv6 address management has been improved regarding tentative 73 addresses. This is visible in that a freshly configured address will not 74 immediately be marked as usable. 75- [*] a lot of bugs have been fixed, please refer to the git log 76 77* Changes in Quagga 0.99.22 78 79- [bgpd] The semantics of default-originate route-map have changed. 80 The route-map is now used to advertise the default route conditionally. 81 The old behaviour which allowed to set attributes on the originated 82 default route is no longer supported. 83- [bgpd] There is now a replace-as option to neighbor ... local-as ... 84 no-prepend. For details, refer to the user documentation. 85- [zebra] An FPM interface has been added. This provides an alternate 86 interface to routing information and is geared at OpenFlow & co. 87- [snmp] AgentX is now supported; the old smux backend is considered 88 deprecated. ospf6d has also had OSPFV3-MIB added. 89- [*] several issues with configuration save/load/apply have been fixed, 90 in particular on ospf "max-metric router-lsa administrative" and 91 "distribute-list", bgpd "no neighbor activate", isisd "metric-style", 92- [*] a lot of bugs have been fixed, please refer to the git log 93 94* Changes in Quagga 0.99.21 95 96- [bgpd] BGP multipath support has been merged 97- [bgpd] SAFI (Multicast topology) support has been extended to propagate 98 the topology to zebra. 99- [bgpd] AS path limit functionality has been removed 100- [babeld] a new routing daemon implementing the BABEL ad-hoc mesh routing 101 protocol has been merged. 102- [isisd] a major overhaul has been picked up. Please note that isisd is 103 STILL NOT SUITABLE FOR PRODUCTION USE. 104- [*] a lot of bugs have been fixed, please refer to the git log 105 106* Changes in Quagga 0.99.10 107 108- [bgpd] 4-byte AS support added 109- [bgpd] MRT format changes to version 2. Those relying on 110 bgpd MRT table dumps may need to update their tools. 111- [bgpd] Added new route-map set statement: "as-path exclude" 112- Zebra RIB updates queue has evolved into a multi-level 113 structure to address RIB consistency issues. 114 115* Changes in Quagga 0.99.2 116 117- [bgpd] Work queues added to bgpd to split up update processing, 118 particularly beneficial when a peer session goes down. AS_PATH 119 parsing rewritten to be clearer, more robust and ready for 4-byte. 120 121- [ripd] Simple authentication is no longer the default authentication 122 mode for ripd. The default is now no-authentication. Any setups which 123 used simple authentication will probably need to update their 124 configuration manually. 125 126- [ospfd] 1s dead-interval with sub-second Hellos feature added. 127 SPF timers now specified in milliseconds, and with adaptive 128 hold-time support. RFC3137 Stub-router support added. Default ABR 129 type is now 'cisco'. 130 131- Solaris least privileges support added. 132 133* Changes in Quagga 0.99.1 134 135- Zserv is now buffered via threads and non-blocking in most cases for both 136 clients and zebra, which should improve responsiveness of daemons when 137 they must send many messages to zebra. 138 139- 'show thread cpu' now displays both cpu+system and wall-clock time, 140 where getrusage() is available. 141 142- Background threads added and workqueue API added, with a 143 'show work-queues' command. Thread scheduling improved slightly. 144 145- Zebra now has a work-queue for RIB processing. See 'show work-queues' in 146 the zebra daemon vty. 147 148- Support for interface renaming on Linux netlink systems. 149 150- GNU Zebra bgpd merges, including BGP Graceful-restart and "match ip 151 route-source" command. 152 153- Automatic logging of backtraces should daemons crash to assist in 154 diagnosis. See the documentation for more information on configuring 155 logging correctly, and set --enable-gcc-rdynamic if compiling with gcc. 156 157* Changes in Quagga 0.98.0 158 159- Logging facilities upgraded. One can now specify a severity level 160 for each logging destination. And a new "show logging" command gives 161 thorough information on the current logging system configuration. 162 163- Watchquagga daemon added. This is not well tested yet. Please try 164 monitor mode first before enabling restart features. It is important 165 to make sure that the various timers are configured with appropriate 166 values for your site. 167 168- BGP route-server support added. See the texinfo documentation. 169 170- OSPF API initialisation is disabled by default even if compiled in. You 171 can enable it with -a/--apiserver command line switch. 172 173- "write-config integrated" vtysh command replaced with "service 174 integrated-vtysh-config" command. 175 176- Router id is now handled by zebra daemon and all daemons receive changes 177 from it. Router id can be overriden in daemons' configurations of course. 178 To fix common router id in zebra daemon you can either install non-127 179 address on loopback or use "router-id x.x.x.x" command. 180 181- "secondary" keyword is removed from ip address configuration. All 182 supported OS'es have their own vision what's secondary address and 183 how to handle it. 184 185- Zebra no longer enables forwarding by default. If you rely on zebra to 186 enable forwarding make sure to add '<ip|ip6> forwarding' statements 187 to your zebra configuration file. 188 189- All libraries are built and used shared, on platforms where libtool 190 supports shared libraries. 191 192- Router advertisement syntax is changed. In usual cases (if you didn't do 193 any fancy stuff) it's enough to change lines in configuration from: 194 "ipv6 nd prefix-advertisement X:X:X:X::/X 2592000 604800 autoconfig on-link" 195 to: 196 "ipv6 nd prefix X:X:X:X::/X" 197 198 All router advertisement options are documented in texi documentation. 199 200- --enable-nssa configure switch is removed. NSSA support is stable enough. 201 202- Daemons don't look at current directory for config file any more. 203 204* Changes in Quagga 0.96.5 205 206- include files are installed in $(prefix)/include/quagga. Programs 207 building against these includes should -I$(prefix)/include and e.g. 208 #include <quagga/routemap.h> 209 210- New option --enable-exampledir puts example files in a separate 211 directory from $(sysconfdir), easing NetBSD pkgsrc hierarchy rules 212 compliance. 213 214- New configure options --enable-configfile-mask and 215 --enable-logfile-mask to set umask values for config and log 216 values. Masks default to 0600, matching previous behavior. 217 218- Import current CVS isisd from SourceForge, then merge it with 219 the Quagga's Framework. 220 221* Changes in Quagga 0.96.4 222 223- Further fixes to ospfd, some relating to the PtP revert. Interface 224lookups should be a lot more robust now. 225 226- Fix for a remote triggerable crash in vty layer. 227 228- Improvements to ripd, and addition of split horizon support. 229 230- Improved bgpd table support, now dumps at time of day intervals rather 231than time from startup intervals. Much improved support for IPv6 table 232dumps. show commands for views improved. 233 234* Changes in Quagga 0.96.3 235 236- revert the 'generic PtP' patch. Means Quagga will no longer work with 237FreeSWAN, however, on the plus side this gets rid of a lot of niggly bugs 238which the PtP patch introduced. 239 240* Changes in Quagga 0.96.2 241 242- Fix crash in ospfd 243 244* Changes in Quagga 0.96.1 245 246- Iron out problem with the privileges definitions 247 248* Changes in Quagga 0.96 249 250- Privilege support, daemons now run with the minimal privileges needed, see 251 the documentation for details. 252 253- NSSA ABR support in ospfd. 254 255- OSPF-API support merged in. 256 257- 6WIND patch merged in. 258 259* Changes in zebra-0.93 260 261* Changes in bgpd 262 263** Configuration is changed to new format. 264 265* Changes in ospfd 266 267** Crush bugs which reported on Zebra ML is fixed. 268 269** Opaque LSA and TE LSA support is added by KDD R&D Laboratories, 270 Inc. 271 272* Chages in ospf6d 273 274** Many bugs are fixed. 275 276* Changes in zebra-0.92a 277 278* Changes in bgpd 279 280** Fix "^$" community list bug. 281 282** Below command's Address Family specific configurations are added 283 284 nexthop-self 285 route-reflector-client 286 route-server-client 287 soft-reconfiguration inbound 288 289* Changes in zebra 290 291** Treat kernel type routes as EGP routes. 292 293* Changes in zebra-0.92 294 295** Overall security is improved. Default umask is 0077. 296 297* Changes in ripd 298 299** If output interface is in simple password authentication mode, 300substruct one from rtemax. 301 302* Changes in bgpd 303 304** IPv4 multicast and IPv6 unicast configuration is changed to so 305called new config. All of AFI and SAFI specific configuration is 306moved to "address-family" node. When you have many IPv6 only 307configuration, you will see many "no neighbor X:X::X:X activate" line 308in your configuration to disable IPv4 unicast NLRI exchange. In that 309case please use "no bgp default ipv4-unicast" command to suppress the 310output. Until zebra-0.93, old config is still left for compatibility. 311 312Old config 313========== 314router bgp 7675 315 bgp router-id 10.0.0.1 316 redistribute connected 317 network 192.168.0.0/24 318 neighbor 10.0.0.2 remote-as 7675 319 ipv6 bgp network 3ffe:506::/33 320 ipv6 bgp network 3ffe:1800:e800::/40 321 ipv6 bgp aggregate-address 3ffe:506::/32 322 ipv6 bgp redistribute connected 323 ipv6 bgp neighbor 3ffe:506:1000::2 remote-as 1 324 325New config 326========== 327router bgp 7675 328 bgp router-id 10.0.0.1 329 network 192.168.0.0/24 330 redistribute connected 331 neighbor 10.0.0.2 remote-as 7675 332 neighbor 3ffe:506:1000::2 remote-as 1 333 no neighbor 3ffe:506:1000::2 activate 334! 335 address-family ipv6 336 network 3ffe:506::/33 337 network 3ffe:1800:e800::/40 338 aggregate-address 3ffe:506::/32 339 redistribute connected 340 neighbor 3ffe:506:1000::2 activate 341 exit-address-family 342 343* Changes in ospfd 344 345** Internal interface treatment is changed.

So both options are removed from configure.in. To 406revert old behavior please specify below option. 407 408--enable-tcp-zebra # TCP/IP socket is used for protocol daemon and zebra. 409--enable-oldrib # Turn on old RIB implementation. 410 411Old RIB implementation will be removed in zebra-0.91. 412 413** From this beta release --enable-multipath is supported. This 414option is only effective on GNU/Linux kernel with 415CONFIG_IP_ADVANCED_ROUTER and CONFIG_IP_ROUTE_MULTIPATH is set. 416 417--enable-multipath=ARG # ARG must be digit. When ARG is 0 unlimit multipath number. 418 419** From this release we do not include guile files. 420 421* Changes in lib 422 423** newlist.[ch] is merged with linklist.[ch]. 424 425** Now Zebra works on MacOS X public beta. 426 427** Access-list can have remark. "access-list WORD remark LINE" define 428remark for specified access-list. 429 430** Key of key-chain is sorted by it's idetifier value. 431 432** prefix-list rule is slightly changed. The rule of "len <= ge-value 433<= le-value" is changed to "len < ge-value <= le-value". 434 435** According to above prefix-list rule change, add automatic 436conversion function of an old rule. ex.) 10.0.0.0/8 ge 8 -> 10.0.0.0/8 437le 32 438 439** SMUX can handle SNMP trap. 440 441** In our event library, event thread is executed before any other 442thread like timer, read and write event. 443 444** Robust method for writing configuration file and recover from 445backing up config file. 446 447** Display "end" at the end of configuration. 448 449** Fix memory leak in vtysh_read(). 450 451** Fix memroy leak about access-list and prefix-list name. 452 453* Changes in zebra 454 455** UNIX domain socket server of zebra protocol is added. 456 457** Fix PointoPoint interface network bug. The destination network 458should be installed into routing table instead of local network. 459 460** Metric value is reflected to kernel routing table. 461 462** "show ip route" display uptime of RIP,OSPF,BGP routes. 463 464** New RIB implementation is added. 465 466Now we have enhanced RIB (routing information base) implementation in 467zebra. New RIB has many new features and fixed some bugs which exist 468in old RIB code. 469 470*** Static route with distance value 471 472 Static route can be specified with administrative distance. The 473 distance value 255 means it is not installed into the kernel. 474 Default value of distance for static route is 1. 475 476 ip route A.B.C.D/M A.B.C.D <1-255> 477 ip route A.B.C.D/M IFNAME <1-255> 478 479 If the least distance value's route's nexthop are unreachable, 480 select the least distance value route which has reachable nexthop is 481 selected. 482 483 ip route 0.0.0.0/0 10.0.0.1 484 ip route 0.0.0.0/0 11.0.0.1 2 485 486 In this case, when 10.0.0.1 is unreachable and 11.0.0.1 is 487 reachable. The route with nexthop 11.0.0.1 will be installed into 488 forwarding table. 489 490 zebra> show ip route 491 S>* 0.0.0.0/0 [2/0] via 11.0.0.1 492 S 0.0.0.0/0 [1/0] via 10.0.0.1 inactive 493 494 If the nexthop is unreachable "inactive" is displayed. You can 495 specify any string to IFNAME. There is no need of the interface is 496 there when you configure the route. 497 498 ip route 1.1.1.1/32 ppp0 499 500 When ppp0 comes up, the route is installed properly. 501 502*** Multiple nexthop routes for one prefix 503 504 Multiple nexthop routes can be specified for one prefix. Even the 505 kernel support only one nexthop for one prefix user can configure 506 multiple nexthop. 507 508 When you configure routes like below, prefix 10.0.0.1 has three 509 nexthop. 510 511 ip route 10.0.0.1/32 10.0.0.2 512 ip route 10.0.0.1/32 10.0.0.3 513 ip route 10.0.0.1/32 eth0 514 515 If there is no route to 10.0.0.2 and 10.0.0.3. And interface eth0 516 is reachable, then the last route is installed into the kernel. 517 518 zebra> show ip route 519 S> 10.0.0.1/32 [1/0] via 10.0.0.2 inactive 520 via 10.0.0.3 inactive 521 * is directly connected, eth0 522 523 '*' means this nexthop is installed into the kernel. 524 525*** Multipath (more than one nexthop for one prefix) can be installed into the kernel. 526 527 When the kernel support multipath, zebra can install multipath 528 routes into the kernel. Before doing that please make it sure that 529 setting --enable-multipath=ARG to configure script. ARG must be digit 530 value. When specify 0 to ARG, there is no limitation of the number 531 of the multipath. Currently only GNU/Linux with netlink interface is 532 supported. 533 534 ip route 10.0.0.1/32 10.0.0.2 535 ip route 10.0.0.1/32 10.0.0.3 536 ip route 10.0.0.1/32 eth0 537 538 zebra> show ip route 539 S>* 10.0.0.1/32 [1/0] via 10.0.0.2 540 * via 10.0.0.3 541 is directly connected, eth0 542 543*** Kernel message delete installed route. 544 545 After zebra install static or dynamic route into the kernel. 546 547 R>* 0.0.0.0/0 [120/3] via 10.0.0.1 548 549 If you delete this route outside zebra, old zebra does not reinstall 550 route again. Now the route is re-processed and properly reinstall the 551 static or dynamic route into the kernel. 552 553** GNU/Linux netlink socket handling is improved to fix race condition 554between kernel message and user command responce. 555 556* Changes in bgpd 557 558** Add show neighbor's routes command. 559 560 "show ip bgp neighbors (A.B.C.D|X:X::X:X) routes" 561 "show ip bgp ipv4 (unicast|multicast) neighbors (A.B.C.D|X:X::X:X) routes" 562 "show ipv6 bgp neighbors (A.B.C.D|X:X::X:X) routes" 563 "show ipv6 mbgp neighbors (A.B.C.D|X:X::X:X) routes" 564 565** BGP passive peer support problem is fixed. 566 567** Redistributed IGP nexthop is passed to BGP nexthop. 568 569** On multiaccess media, if the nexthop is reachable nexthop is passed 570as it is. 571 572** Remove zebra-0.88 compatibility commands. 573 574 "match ip prefix-list WORD" 575 "match ipv6 prefix-list WORD" 576 577 Instead of above please use below commands. 578 579 "match ip address prefix-list WORD" 580 "match ipv6 address prefix-list WORD" 581 582** Fix bug of holdtimer is not reset when bgp cleared. 583 584** "show ip bgp summary" display peer establish/drop count. 585 586** Change "match ip next-hop" argument from IP address to access-list 587name. 588 589** When "bgp enforce-first-as" is enabled, check EBGP peer's update 590has it's AS number in the first AS number in AS sequence. 591 592** New route-map command "set community-delete COMMUNITY-LIST" is 593added. Community matched the CoMMUNITY-LIST is removed from the 594community. 595 596** BGP-MIB implementation is finished. 597 598** When BGP connection comes from unconfigured IP address, close 599socket immediately. 600 601** Do not compare router ID when the routes comes from EBGP peer. 602When originator ID is same, take shorter cluster-list route. If 603cluster-list is same take smaller IP address neighbor's route. 604 605** Add "bgp bestpath as-path ignore" command.

When interface goes up, restore the routes to the routing 1283table. 1284 1285** `show interface' show interface's statistics on Linux and BSD with 1286routing socket. 1287 1288** Now zebra can get MTU value on BSDI/OS. 1289 1290* Changes in bgpd 1291 1292** Add capability option support based upon 1293draft-ietf-idr-bgp4-cap-neg-04.txt. 1294 1295** Add `show ipv6 bgp prefix-list' command. 1296 1297** Check self AS appeared in received routes. 1298 1299** redistribute route-map support is added. 1300 1301** BGP packet dump feature compatible with MRT. 1302 1303* Changes in ripd 1304 1305** Fix bug of `timers basic' command's argument format. 1306 1307* Changes in ripngd 1308 1309** Calculate max RTE using interface's MTU value. 1310 1311* Changes in ospfd 1312 1313** Some correction to LSU processing. 1314 1315** Add check for lsa->refresh_list. 1316 1317* Changes in ospf6d 1318 1319** Many debug feature is added. 1320 1321* Changes in zebra-0.81 1322 1323** SNMP support is disabled in default.--enable-snmp option is added 1324to configure script. 1325 1326* Changes in bgpd 1327 1328** Fix FSM bug which introduced in zebra-0.80. 1329 1330* Changes in zebra-0.80 1331 1332* access-list 1333 1334 New access-list name space `ipv6 access-list' is added. At the same 1335 time, `access-list' statemant only accepts IPv4 prefix. Please be 1336 careful if you use IPv6 filtering. You will need to change your 1337 configuration. For IPv6 filtering please use `ipv6 access-list'. 1338 1339 As of zebra-0.7x, user can use `access-list' for both IPv4 and IPv6 1340 filtering. 1341 1342 ! zebra-0.7x 1343 access-list DML-net permit 203.181.89.0/24 1344 access-list DML-net permit 3ffe:506::0/32 1345 access-list DML-net deny any 1346 ! 1347 1348 Above configuration is not valid for zebra-08x. Please add `ipv6' 1349 before 'access-list' when you configure IPv6 filtering. 1350 1351 ! zebra-0.8x 1352 access-list DML-net permit 203.181.89.0/24 1353 access-list DML-net deny any 1354 ! 1355 ipv6 access-list DML-net permit 3ffe:506::0/32 1356 ipv6 access-list DML-net deny any 1357 ! 1358 1359* prefix-list 1360 1361 And also new prefix-list name space `ipv6 prefix-list' is added. It 1362 is the same as the change of `access-list'. `ip prefix-list' now only 1363 accept IPv4 prefix. It was source of confusion that `ip prefix-list' 1364 can be used both IPv4 and IPv6 filtering. Now name space is separated 1365 to clear the meaning of the filter. 1366 1367 If you use `ip prefix-list' for IPv6 filtering, please change the 1368 stetement. 1369 1370 ! zebra-0.7x 1371 ip prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24 1372 ip prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28 1373 ip prefix-list 6bone-filter seq 12 deny 3ffe::/16 1374 ip prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16 1375 ip prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35 1376 ip prefix-list 6bone-filter seq 30 deny any 1377 ! 1378 1379 Now user can explicitly configure it as IPv6 prefix-list. 1380 1381 ! zebra-0.8x 1382 ipv6 prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24 1383 ipv6 prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28 1384 ipv6 prefix-list 6bone-filter seq 12 deny 3ffe::/16 1385 ipv6 prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16 1386 ipv6 prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35 1387 ipv6 prefix-list 6bone-filter seq 30 deny any 1388 ! 1389 1390* RIP configuration 1391 1392 If you want to filter only default route (0.0.0.0/0) and permit other 1393 routes, it was hard to do that. Now `ip prefix-list' can be used for 1394 RIP route filtering. 1395 1396 New statement: 1397 1398 `distribute-list prefix PLIST_NAME (in|out) IFNAME' 1399 1400 is added to ripd. So you can configure on eth0 interface accept all 1401 routes other than default routes. 1402 1403 ! 1404 router rip 1405 distribute-list prefix filter-default in eth0 1406 ! 1407 ip prefix-list filter-default deny 0.0.0.0/0 le 0 1408 ip prefix-list filter-default permit any 1409 ! 1410 1411* RIPng configuration 1412 1413 Same change is done for ripngd. You can use `ipv6 prefix-list' for 1414 filtering. 1415 1416 ! 1417 router ripng 1418 distribute-list prefix filter-default in eth0 1419 ! 1420 ipv6 prefix-list filter-default deny ::/0 le 0 1421 ipv6 prefix-list filter-default permit any 1422 ! 1423 1424* BGP configuration 1425 1426 So far, Multiprotocol Extensions for BGP-4 (RFC2283) configuration is 1427 done with traditional IPv4 peering statement like blow. 1428 1429 ! 1430 router bgp 7675 1431 neighbor 3ffe:506::1 remote-as 2500 1432 neighbor 3ffe:506::1 prefix-list 6bone-filter out 1433 ! 1434 1435 For separating configuration IPv4 and IPv6, and for retaining Cisco 1436 configuration compatibility, now IPv6 configuration is done by IPv6 1437 specific statement. IPv6 BGP configuration is done by statement which 1438 start from `ipv6 bgp'. 1439 1440 ! 1441 router bgp 7675 1442 ! 1443 ipv6 bgp neighbor 3ffe:506::1 remote-as 2500 1444 ipv6 bgp neighbor 3ffe:506::1 prefix-list 6bone-filter out 1445 ! 1446 1447 At the same time some IPv6 specific commands are deleted from IPv4 1448 configuration. 1449 1450 o redistribute ripng 1451 o redistribute ospf6 1452 o neighbor PEER version BGP_VERSION 1453 o neighbor PEER interface IFNAME 1454 1455 Those commands are only accepted as like below. 1456 1457 o ipv6 bgp redistribute ripng 1458 o ipv6 bgp redistribute ospf6 1459 o ipv6 bgp neighbor PEER version BGP_VERSION 1460 o ipv6 bgp neighbor PEER interface IFNAME 1461 1462 And below new commands are added. 1463 1464 o ipv6 bgp network IPV6_PREFIX 1465 o ipv6 bgp redistribute static 1466 o ipv6 bgp redistribute connected 1467 o ipv6 bgp neighbor PEER remote-as <1-65535> [passive] 1468 o ipv6 bgp neighbor PEER ebgp-multihop [TTL] 1469 o ipv6 bgp neighbor PEER description DESCRIPTION 1470 o ipv6 bgp neighbor PEER shutdown 1471 o ipv6 bgp neighbor PEER route-reflector-client 1472 o ipv6 bgp neighbor PEER update-source IFNAME 1473 o ipv6 bgp neighbor PEER next-hop-self 1474 o ipv6 bgp neighbor PEER timers holdtime <0-65535> 1475 o ipv6 bgp neighbor PEER timers keepalive <0-65535> 1476 o ipv6 bgp neighbor PEER send-community 1477 o ipv6 bgp neighbor PEER weight <0-65535> 1478 o ipv6 bgp neighbor PEER default-originate 1479 o ipv6 bgp neighbor PEER filter-list FILTER_LIST_NAME (in|out) 1480 o ipv6 bgp neighbor PEER prefix-list PREFIX_LIST_NAME (in|out) 1481 o ipv6 bgp neighbor PEER distribute-list AS_LIST_NAME (in|out) 1482 o ipv6 bgp neighbor PEER route-map ROUTE_MAP_NAME (in|out) 1483 1484 And some utility commands are introduced. 1485 1486 o clear ipv6 bgp [PEER] 1487 o show ipv6 bgp neighbors [PEER] 1488 o show ipv6 bgp summary 1489 1490 I hope these changes are easy to understand for current Zebra users... 1491 1492* To restrict connection to VTY interface. 1493 1494 It used to be both IPv4 and IPv6 filter can be specified with one 1495 access-list. Then the access-list can be appried to VTY interface 1496 with `access-class' stetement in `line vty' node. Below is example in 1497 zebra-0.7x. 1498 1499 ! 1500 access-list local-only permit 127.0.0.1/32 1501 access-list local-only permit ::1/128 1502 access-list local-only deny any 1503 ! 1504 line vty 1505 access-class local-only 1506 ! 1507 1508 Now IPv4 and IPv6 filter have each name space. It is not possible to 1509 specify IPv4 and IPv6 filter with one access-list. For setting IPv6 1510 access-list in `line vty', `ipv6 access-class' statement is 1511 introduced. Let me show the configuration in zebra-0.8x. 1512 1513 ! 1514 access-list local-only permit 127.0.0.1/32 1515 access-list local-only deny any 1516 ! 1517 ipv6 access-list local-only permit ::1/128 1518 ipv6 access-list local-only dny any 1519 ! 1520 line vty 1521 access-class local-only 1522 ipv6 access-class local-only 1523 ! 1524 1525* route-map 1526 1527 New IPv6 related route-map match commands are added. 1528 1529 o match ipv6 address 1530 o match ipv6 next-hop 1531 1532 Please change your configuration if you use IP match statement for 1533 IPv6 route. 1534 1535 zebra-0.7x config 1536 ================= 1537 ! 1538 access-list all permit any 1539 ! 1540 route-map set-nexthop permit 10 1541 match ip address all 1542 set ipv6 next-hop global 3ffe:506::1 1543 set ipv6 next-hop local fe80::cbb5:591a 1544 ! 1545 1546 zebra-0.8x config 1547 ================= 1548 ! 1549 ipv6 access-list all permit any 1550 ! 1551 route-map set-nexthop permit 10 1552 match ipv6 address all 1553 set ipv6 next-hop global 3ffe:506::1 1554 set ipv6 next-hop local fe80::cbb5:591a 1555 ! 1556 1557* zebra connection 1558 1559 Protocol daemon such as ripd, bgpd, ospfd will reconnect zebra daemon 1560 when the connection fail. Those daemons try to connect zebra every 10 1561 seconds first three trial, then the interval changed to 60 seconds. 1562 After all, if ten connections are fail, protocol daemon give up the 1563 connection to the zebra daemon. 1564 1565* SNMP support (is not yet finished) 1566 1567 Zebra uses SMUX protocol (RFC1227) for making communication with SNMP 1568 agent. Currently lib/smux.c can be compiled only with ucd-snmp-4.0.1 1569 and http://ucd-snmp.ucdavis.edu/patches/012.patch. It can not be 1570 compiled with ucd-snmp-3.6.2. 1571 1572 After applying the patch to ucd-snmp-4.0.1, please configure it with 1573 SMUX module. 1574 1575 % configure --with-mib-modules=smux 1576 1577 After compile & install ucd-snmp-4.0.1, you will need to configure 1578 smuxpeer. I'm now using below configuration. 1579 1580 /usr/local/share/snmp/snmpd.conf 1581 ================================ 1582 smuxpeer 1.3.6.1.6.3.1 test 1583 1584 Above 1.3.6.1.6.3.1 and test is temporary configuration which is hard 1585 coded in lib/smux.c. Yes, I know it is bad, I'll change it ASAP. 1586 1587* HUP signal treatment 1588 1589 From zebra-0.80, ripd will reload it's configuration file when ripd 1590 receives HUP signal. Other daemon such as bgpd, ospfd will support 1591 HUP signal treatment soon. 1592 1593* Changes in zebra-0.79 1594 1595* Changes in zebra 1596 1597** Broadcast address setting on Linux box bug is fixed. 1598 1599** Protocol daemon can install connected IPv6 route into the kernel. 1600 1601** Now zebra can handle blackhole route. 1602 1603* Changes in ripd 1604 1605** Add route-map feature for RIP protocol. 1606 1607** In case of RIP version 2 routing table entry has IPv4 address and 1608netmask pair which host part bit is on, ignore the entry. 1609 1610* Changes in ripngd 1611 1612** Change CMSG_DATA cast from (u_char *) to (int *).
