Just as a reminder, here is what we converged on at IETF89 for text in the homenet arch. The “zero or one” protocol message was clear. I don’t recall a clear answer on whether to pass config info via the routing protocol or a separate protocol, but as HNCP shapes up as a proposal I suspect the tradeoffs will become clearer towards an answer there. "At most one routing protocol should be in use at a given time in a given homenet. In some simple topologies, no routing protocol may be needed. If more than one routing protocol is supported by routers in a given homenet, then a mechanism is required to ensure that all routers in that homenet use the same protocol."
