If an IGP-only router only needs to route to the next-hop of BGP
speakers, why would it need to know external routes? The BGP routers
know next hops, and know they are reachable. That's not a
synchronization issue because you aren't synchronizing the external
information, no?
I picture these IGP routers much in the role of RFC2547 P routers,
with or without MPLS. The BGP speakers are the equivalent of PE.
