Mike,
        While your router will use BGP to determine its next hop destination, 
if that next hop is no directly reachable over l2 it will use whatever route it 
uses for that destination. Which as soon as you hand it off to the first router 
it will determine the patch after that, unless you use gre tunnels or some 
other type of tunneling environment.
