Draft-ietf-ipv6-2461bis-02 update

Objective

• Summarise the status of the draft
• Briefly describe the updates
• Describe plans for the next rev

Status

• Draft passed WG LC
• Late Comments from Pekka Savola

included in the current revision (see Appendix F for changes)

• Further comments on processing of

messages received without SLLAO are not completely addressed in the draft.

Receiving messages without SLLAO

• Problem: RFC 2461 (and bis) miss the case

where an RS, NS or NA are received without an SLLAO. The current revision of the draft only addresses this issue for the RS.

• The problem is not significant for NAs as

they are inherently unreliable and no response is expected.

Suggestion

• Text to go under section 7.2 (from Greg

Daley):
