Alan,
Looks good.

1. the list of changes /reasons compared with rfc6824 not included. I can submit as separate draft, if you prefer to inclusion in your doc.

2. I  made a comment on Fig 12 (just checking you meant to ignore it - don’t mind!)

And in Fig 12
|        Truncated HMAC (8 octets, if length > 10 octets)       |

Could this be made more straightforward? Ie spell out when length is >10 octets ie IPv6 (if I understand it). This also seems to mean that IPv4 doesn’t include the HMAC, is this right??

3. I made a comment on Section 2:  Need to add sub-sections on closing subflow & fast close & fallback
Would be nice, but I won't insist if it's too much work

Thanks
phil

Hi all,

I believe this new version addresses all last call/review comments we received for rfc6824bis, with the exception of adding a possible “changes since RFC6824” section.

Could all reviewers please check this new version and ensure we have handled your review comments appropriately?

Many thanks,
Alan
