Debugging BGP-based Service Engine Configurations

This section explains the debugging steps if a BGP session does not come up.

1. Double check the configuration on the router and NSX Advanced Load Balancer. Ensure that the peer IPs, subnets, and AS numbers are correct.

2. Verify the MD5 passwords are the same on the router and NSX Advanced Load Balancer.

3. Run show serviceengine bgp to determine the state of the BGP session initiated by the NSX Advanced Load Balancer SE.

4. Verify there are no ACLs/ route maps on the router preventing the sessions/ advertisements.

5. Additionally, if needed, check the packet capture using tcpdump (tcpdump -M ) on the router and check BGP negotiations.
