Hi,guys,I hava received a BGP NOTIFICATION with error code 6/6.What's meaning error code 6/6 ? OR What kind of is the error ? For example,if there is a wrong AS,the error code is 2/2.

Oct 21 03:52:30.733 UTC: %BGP-3-NOTIFICATION: received from neighbor 6/6 (cease) 0 bytes

Oct 21 03:52:30.733 UTC: %BGP-5-ADJCHANGE: neighbor Down BGP Notification received

    The 6/6 means other configuration change if you look at the RFC.


    The (cease) is when the remote peer has an administratively shutdown. I already get it in production, so I made a test to be sure.


    With two Cisco router you do not have the notification. But if you deactivate the bgp neighbor on a Juniper you have :


    *Mar  1 00:14:41.363: BGP: rcv message type 3, length (excl. header) 2

    *Mar  1 00:14:41.363: %BGP-3-NOTIFICATION: received from neighbor 6/3 (cease) 0 bytes

    *Mar  1 00:14:41.367: BGP: went from Established to Closing


    I have a 6/3 so it seem the Juniper correctly send the notification. Do you now what device is in front of yours ?
