We need to see the output for "show ip route 9.9.0.2" as well.  If often means the next hop for 9.9.0.2 is not in the BGP table - so verify that first. It it is not then resolve that issue.

9.9.0.1 is recursively routed via 9.9.0.2, so if you can't get to 9.9.0.2 you can't get to 9.9.0.1.

I need the output of "show ip route 9.9.0.2".
