Dear all;

We seeing a number of situation (e.g., draft-collink-v6ops-ent64pd and draft-ietf-snac-simple) where there's a need for a node to advertise that it owns a prefix to neighbor routers, and that packets sourced at (in case of multihoming) or destinated to (in case of a stub) that prefix should be passed to this node.

At the moment there is magic (read proprietary code) that ties, say, the DHCP server that delegates a prefix and the routers that install a route for the delegated prefix via the delegated node. With this draft, the delegated node can advertise the prefix to the routers in a standard/interoperable fashion.

Bottom line is that it is getting more urgent to complete the work and I intend to ask for adoption at IETF 117. 

To progress on this, reviews would be much appreciated between now and the next IETF.

Many thanks in advance 😊

Pascal
