Severity: 3-Major


BGP neighbor using peer-group with 'capability graceful-restart' enabled (which is the default). However, on the system, peer-group defaults to disable. Because there is no config statement to enable 'capability graceful-restart' after restart, it gets turned off after config load, which also turns it off for any BGP neighbor using it.


Because peer-group is set to disable by default, and there is no operation to enable it after restart, 'capability graceful-restart' gets turned off after config load, and neighbors using it from peer-group get turned off as well.


- Neighbor configured to use peer-group. - Peer-group configured with capability graceful-restart, but with the default: disabled.


Re-issue the commands to set peer-group 'capability graceful-restart' and 'clear ip bgp *' to reset BGP neighbors.

Fix Information

The peer-group now has 'capability graceful-restart' enabled by default, so this issue no longer occurs.

Behavior Change

In this release, peer-group has 'capability graceful-restart' enabled by default.
