Unreachable next hop tunnel
The following example shows how to obtain a reachable next hop IP address. In
an IBGP peer relationship is established between Router A and Router B, and an EBGP peer
relationship is established between Router B and Router C. Router A imports the route 1.1.1.9/32,
and Router C imports the route 3.3.3.9/32.
