Learning Our Routes back on BGP

netbeginner · ‎03-14-2021

Hi All,

We have BGP peering configured with remote end. Observed strange behaviour.

We are learning our routes back to us which we are only advertising to remote end. This is creating a communication issue. Can anyone suggest what happened wrong.

This should not occur due to as-path loop prevention, are you performing any aggregation?

sh run | sec router

In addition to the bgp section of the config it would be helpful to have several other things:

- a diagram showing the topology of the network.

- the output of show ip bgp neighbor

- the output of show ip bgp sum

- the output of show ip bgp
