Can somebody help me out please?? I am having a routing loop to this route 22.214.171.124/18.
I have 2 eBGP routers multihomed to two isps. 1 isp connection to each router. when i do a show ip route to one of the router, it has a route the this network going out to its ebgp neighbor. But somehow, doing a traceroute to this network, the router uses another exit link -- to its ibgp neighbor.
Now, the other router has the same route with its exit to the previous router. So now, i am getting a loop.
Why would a router have a route on its forwarding table but doesn't use it?
here's a snapshot of the 'show ip route' and trace result:
I1#sh ip route 126.96.36.199
