Disabling BGP to establish a session to a peer or peer group This task enables you to temporarily tear down the BGP session to a specific peer or peer group so that you can perform network upgrade and maintenance without needing to delete and reconfigure the peer or peer group. To recover the session, execute the undo peer ignore command. To disable BGP to establish a session to a peer or peer group (IPv4): Step 1. Enter system view. 2.
