The value 522 direct indicates that a packet is encapsulated 523 directly within a normal IP header, with no 524 intermediate header, and unicast to the remote tunnel 525 endpoint (e.g., an RFC 2003 IP-in-IP tunnel, or an RFC 526 1933 IPv6-in-IPv4 tunnel). The value minimal indicates 527 that a Minimal Forwarding Header (RFC 2004) is 528 inserted between the outer header and the payload 529 packet. The value UDP indicates that the payload 530 packet is encapsulated within a normal UDP packet 531 (e.g., RFC 1234). 532 533 The values sixToFour, sixOverFour, and isatap 534 indicates that an IPv6 packet is encapsulated directly 535 within an IPv4 header, with no intermediate header, 536 and unicast to the destination determined by the 6to4, 537 6over4, or ISATAP protocol. 538 539 The remaining protocol-specific values indicate that a 540 header of the protocol of that name is inserted 541 between the outer header and the payload header. 542 543 The assignment policy for IANAtunnelType values is 544 identical to the policy for assigning IANAifType 545 values." 546 SYNTAX INTEGER { 547 other(1), -- none of the following 548 direct(2), -- no intermediate header 549 gre(3), -- GRE encapsulation 550 minimal(4), -- Minimal encapsulation 551 l2tp(5), -- L2TP encapsulation 552 pptp(6), -- PPTP encapsulation 553 l2f(7), -- L2F encapsulation 554 udp(8), -- UDP encapsulation 555 atmp(9), -- ATMP encapsulation 556 msdp(10), -- MSDP encapsulation 557 sixToFour(11), -- 6to4 encapsulation 558 sixOverFour(12), -- 6over4 encapsulation 559 isatap(13), -- ISATAP encapsulation 560 teredo(14) -- Teredo encapsulation 561 } 562 563 END 564 565 566 567 568 569 570 571 572 573
