RFC 2461 explicitly doesn't require checking the set of prefixes (but it does say to check that the lifetimes on a prefix which both routers advertise are consistent, etc). *If* we are going to change this, I don't think it should be a subtle setence in 2461bis; I think it should be a standalone RFC so that operators and implementors pay attention. If we do that, making 2461bis have the same message makes sense. Perhaps writing up a draft for v6ops would be a good start. Pointing out that the current flexibility (of different prefixes advertised by different routers) doesn't have any operational use, but allowing hosts, for Nemo and multihoming reasons, to tell when there are source address constraints might have some use.
