Usage Guidelines

Usage Scenario

If a device supports GR but a BGP peer specified on the device does not support GR, you can run the peer local-graceful-restart enable command on the device to enable local GR for the peer. This configuration ensures that the device does not delete the routes received from the peer and related forwarding entries before the GR time elapses, thereby preventing traffic interruption.

Example

# Enable local GR for a specified peer on a device.
