what if the routers are in the same AS, is this some new use of
confederates?

Jim

p.s. to answer the *original* question, from a protocol perspective, as
long as there are LSPs edge to edge (no need to be tunnels), one doesn't
have to run BGP on interior nodes.  In reality, there are other issues
that might keep one running it, though.
