Dennis -
When a route is received via ebgp, and passed into ibgp....the next hop
is not manipulated. Therefore, the routers within the AS will not know
how to reach this next hop (learned by ebgp).
By using the next-hop-self command, the AS border router is set as the
next hop. This allows the other routers within the AS reachability,
since the border router knows how to reach the route on the next AS.
