You need to run iBGP on every router in the AS that needs to see BGP
routes. Depending on what you're calling a "distribution" router, you
might be able to get away with just using default routes. The main
reason for running BGP on distribution or access routers is if you
want those routers to make best-path decisions or if you have
BGP-speaking customers.

Do you have a routable address configured on lo0? Even if you do, I
suspect what's happening is that it's choosing 127.0.0.1, which can't
reach the other router. Try this:

  neighbor OCE-IBGP update-source 1.2.3.4

where 1.2.3.4 is a /32 alias on lo0. Obviously all the other routers
need to have host routes for that loopback addresses. The typical
configuration is to carry those loopback routes in an IGP (like OSPF).
