Core Issue
These are among the common symptoms of recursive routing failure:
- Constant deletion and reinsertion of Border Gateway Protocol (BGP) routes into the routing table
- Loss of connectivity towards destinations learned through the BGP
Resolution
To avoid recursive routing loops with BGP, configure a static route for the BGP peer IP address.
For a sample configuration of a static route refer to Rtr-A.
To determine the cause of flapping routes, refer to Troubleshooting Flapping BGP Routes (Recursive Routing Failure).
