Next hop failure would not give a best path. You have to be the best path
to be handed to the routing table to begin with. Only after being handed to
the routing table can the route be rejected so you have a RIB failure. ;)

So it's a good route in BGP. But the routing table has a better AD path.
Try "show ip route x.x.a.a" and see what shows up!

Hello Joshua,

The next hop addresses are reachable and I have tried using the
