issue arose out of a simple case of not paying attention to what I was typing into the CLI which consequently created the problem described here. After entering in the wrong configuration which I had not realized that I did, I started to get the following error messages on two routers I was attempting to establish an iBGP peering with. Error message R9# *Jul 8 05:58:25.107: %BGP-3-NOTIFICATION: received from neighbor 192.168.81.8 active 6/0 (CEASE: unknown subcode) 0 bytes *Jul 8 05:58:25.111: %BGP-5-NBR_RESET: Neighbor 192.168.81.8 active reset (BGP Notification received) *Jul 8 05:58:25.119: %BGP-5-ADJCHANGE: neighbor 192.168.81.8 active Down BGP Notification received *Jul 8 05:58:25.123: %BGP_SESSION-5-ADJCHANGE: neighbor 192.168.81.8 IPv4 Unicast topology base removed from session BGP Notification received R8# *Jul 8 05:59:27.635: %BGP-5-NBR_RESET: Neighbor 192.168.89.9 passive reset (BGP Notification sent) *Jul 8 05:59:27.647: %BGP-5-ADJCHANGE: neighbor 192.168.89.9 passive Down Error during connection collision *Jul 8 05:59:32.691: %BGP-3-NOTIFICATION: sent to neighbor 192.168.89.9 passive 6/0 (CEASE: unknown subcode) 0 bytes *Jul 8 05:59:36.851: %BGP-5-NBR_RESET: Neighbor 192.168.89.9 passive reset (BGP Notification sent) *Jul 8 05:59:36.863: %BGP-5-ADJCHANGE: neighbor 192.168.89.9 passive Down Error during connection collision Topology So I set out to figure out what was causing this annoying error. Since the errors were related to neighborship I began by looking into the neighbors states on both R8 and R9 routers.
