Michael,
Look at the routes and pay attention to the next hop for each external
route. Can your router reach that next hop? If not, BGP will not install the
route in the route table. Sending router can use the neighbor x.x.x.x
next-hop-self command or you can get the route via IGP if it works in your
topology.
