What good is "full routes from a single peer"? Just point a default
route there...

As per the routerperformance.pdf, the 2911 is (regarding packet forwarding)
nearly as fast as the NPE-400, and the 2921 would be somewhat faster - so
if then NPE-400 is sufficient now, the 2921 should do well as backup.
OTOH, why bother with BGP full tables if all you have is a single peer.
