If a correct source is not chosen the return path may not be symmetric and cause issues to the subscriber. For example native IPv6 and 6rd are running concurrently in a home served by broadband access.
I can't see how can routing information from two sources be merged if there is a conflict.

I didn't say people should do these things, just that there are things that *can be* delivered via RA and that *can be* delivered via DHCP, and that *can conflict*. If things do conflict, then something has to decide, on some criterion or other, which to honour (or to honour neither of course). My post was in answer to a question from someone about about how things could conflict. That's all. > Enterprises MAY advertise a search lists when configuring their own > machines.

And if their DHCP server says one thing and their RAs are saying another, then there should be a sane default for deciding which to use. That's all this is about.
