Correct... It's not a BGP problem.  BGP is how we trade routing information.
Today, BGP trades prefix data and AS PATH data.  If we find a way that IDR
can be done strictly on AS PATH, then, we can take most of the prefixes
out of BGP and leave all the AS PATH data there, and, BGP hasn't changed.

The problem is not BGP... Yes, some possible solutions involve changing
BGP.  Other possible solutions involve changing the way we use BGP.

Sure.  In the long run, a modified BGP or new routing protocol will be
required.  However, in the short run, I think we can use existing BGP
in concert with a scalable solution which will buy time to do the
changes to the routing protocol for later optimization.

Vince and I actually agree about this.  This is rare, but, he and
I actually agree that ID/LOC split is the only viable long term
solution that has been presented.
