Re: [Anima] I-D Action: draft-ietf-anima-prefix-management-04.txt

Hi,

This version follows a careful review by Toerless. There are three
significant changes:

1. There is some explanation, mainly in an Appendix, about how this
solution can co-exist with existing mechanisms for prefix delegation,
especially DHCPv6/PD. In a few words, we'd use the autonomic solution
to provide prefixes to edge devices, and conventional methods to
delegate prefixes at the edge. Thus the client routers don't need to
be in the trusted autonomic domain.

2. There is not complete agreement among the authors, but for now we have
removed the "PD" flag from the GRASP objective, because the use case for
it was very unclear (why bother to negotiate with GRASP and then add an
extra step with DHCPv6?).

3. We have included two possible ways to add IPv4 prefix management.

Comments are needed. Especially, should we include one of the IPv4
mechanisms in the final version?

For people who like running code, there's a demo version at

A screen shot of four instances working together is at
