Explanation
In the configuration shown, BFD (Bidirectional Forwarding Detection) liveness detection is globally configured, but for BFD to work with specific BGP neighbors, it must be configured under each BGP neighbor or BGP group. Without specific BFD configuration at the neighbor or group level, BFD will not be used to monitor the BGP sessions, which might be causing the BGP neighbors not to establish a connection.
