>RFC2473: Generic Packet Tunneling in IPv6 Specification
i have a couple of comments on this document. i'd like to see these
addressed before this document proceeding further.
itojun
- tunnel encapsulation option (4.1.1, 5.1) does not seem to be widely
implemented/operated. if my observation is correct, i'd suggest droppping it.
- TOS/traffic class field processing rule is not friendly with ECN
(6.4). i'd propose to add reference to RFC3168 section 9 and follow
them.
- icmp message relay/translation (8) does not seem to be widely
implemented/operated, and could even be abused (open relay of packet - it is
not mentioned in security issues section). if my observation is correct,
i'd suggest removing the rule.
