Hi all,

Three of us were asked by the Dutch academic network Surfnet to write an overview of IPv6-in-IPv4 tunneling mechanisms. To benefit the wider community, we did so in the form of a draft, that we intend to submit to the RFC Editor as an independent submission.

However, we would very much appreciate reviews and comments from within the IETF. These are the mechanisms we discuss:

3.  Tunnel Mechanisms  . . . . . . . . . . . . . . . . . . . . . .  5
    3.1.  Configured Tunnels (Manual Tunnels / 6in4) . . . . . . . .  6
    3.2.  Automatic Tunneling  . . . . . . . . . . . . . . . . . . .  7
    3.3.  IPv6 over IPv4 without Explicit Tunnels (6over4) . . . . .  8
    3.4.  Generic Routing Encapsulation (GRE)  . . . . . . . . . . .  9
    3.5.  Connection of IPv6 Domains via IPv4 Clouds (6to4)  . . . .  9
    3.6.  Anything In Anything (AYIYA) . . . . . . . . . . . . . . . 10
    3.7.  Intra-site Automatic Tunnel Addressing (ISATAP)  . . . . . 11
    3.8.  Tunneling IPv6 over UDP through NATs (Teredo)  . . . . . . 12
    3.9.  IPv6 Rapid Deployment (6rd)  . . . . . . . . . . . . . . . 13
    3.10. Native IPv6 behind NAT44 CPEs (6a44) . . . . . . . . . . . 14
    3.11. Peer-to-Peer IPv6 on Any Internetwork (6bed4)  . . . . . . 15
    3.12. The Locator/ID Separation Protocol (LISP)  . . . . . . . . 16
  4.  Related Protocols  . . . . . . . . . . . . . . . . . . . . . . 17
    4.1.  Tunnel Information and Control protocol (TIC)  . . . . . . 17
    4.2.  Tunnel Setup Protocol (TSP)  . . . . . . . . . . . . . . . 18
    4.3.  Dual-Stack Lite (Softwire) . . . . . . . . . . . . . . . . 19

Thanks!
