We need to decide, if we want prefix assignment and distribution of other configuration information integrated in a routing protocol. Depending on that decision we either need to design a separate protocol to do that, or we need to add support for that in a routing protocol. Prefix assignment is simpler with a link-state protocol, so that's why I have limited the choice of routing protocols for that branch. I have assumed there is agreement to have a single routing protocol in the home, and not support multiple.

I agree with the decision chart.

While I initially was very enthusiastic about integrating prefix assignment into a routing protocol, I am now more sceptic to this approach.

So question if we don't use the routing protocol for prefix assignment, what should go in there? Should we have a new protocol for service discovery? Topology discovery? Anything else? Anyhow, the src/dst enhancements for the IGP has to be done, I don't see much alternative to that.

Anyhow, I don't think DHCPv6-PD is a good method to assign prefixes to interfaces.
