Brian, Sure, but we have learnt that the matter of route injection is a thorny problem. If you do not topologically restrict the problem, how do you solve it? Among separate administrative domains.

The IPAM (IP address Management, and by extension IP Prefix Management) software can be implemented in a computer sold as a router, but there is no requirement that it be, and it usually is not. As a matter of fact, if a router is a system that forwards messages directed to addresses other than its own, in the context of an application such as a DHCPv6 address/prefix management process, it is acting as a host, not a router. >> >> Prefix delegation, more so than address assignment is coupled with the routing system. >> Which is why RFC3633 only described a model where the delegating router and requesting router was directly connected. > > They're coupled, but it isn't logically required that the entity that gives > prefix P to a device is also the upstream router that will include P in an > aggregate.
