> Agreed.  However the design team is stepping gingerly.   We first did a single IPv6 CE router in the home case which is the Basic IPv6 CE Router document in the RFC Editor Queue.  The bis document covers a specific two-router case.   It's only the fact that making all IPv6 features of the CE Router work with multihoming is the issue.  For some features solutions don't even exist.  So what does a document like ours propose for solution to use? 

Nothing, I think. Until we have clarity on the issues
in draft-v6ops-multihoming-without-nat66 I don't see
what we can say, beyond MUST support multiple
prefixes and MAY support multiple WAN interfaces.
