Classical DHCPv6 Prefix Delegation involves a Requesting Router and a Delegating Router.
Recent discussions and drafts have suggested that the "Requesting Router" could be a
simple host that receives a Prefix Delegation (of whatever prefix length) for its own
multi-addressing purposes. Meaning, that the host configures addresses from the
prefix and assigns them, e.g., to a loopback interface so that its local applications can
each use a different address if desired.
But, whether the node uses the delegated prefix for multi-addressing (as a host
would) or for assignment to downstream links (as a router would), it still has the
same appearance from the outside world. So, from the outside world, the node
would appear as a multi-addressing host even if it is acting as a router on its
downstream links. The only time it would look like a router is if it engaged in a
dynamic routing protocol on the interface over which it received the prefix.
Any thoughts?
Thanks - Fred
