It has been done a long time ago, IMHO.

I wonder whether I am the only one seeing this, but we already have
a (albeit routing-) locator (ASN) and an identifier (IP address),
that are pretty much distinct and where the routing locator is not
used inside the "local" network, but only outside. There's your
edge/core boundary.

Every multi-homer will be needing their own ASN, so that's what clutters
up your routing tables. It's economy there. Btw, a lot of ASNs advertise
one network only. People surely think multihoming is important to them
(and I cannot blame them for that).

Hierarchical routing is one possible solution, with a lot of drawbacks
and problems. Forget about geographic hierarchies; there's always people
who do not peer. Visibility radius limitation is another (I cannot believe
the idea is new, I only don't know what it's called).

Cheers,
