The peer graceful-restart timer wait-for-rib command sets the maximum duration for a BGP restarter to wait for the End-of-RIB flag from a specified peer.
The undo peer graceful-restart timer wait-for-rib command deletes the configured duration.
By default, a BGP restarter waits for the End-of-RIB flag from a specified peer for a maximum of 600s.
Usage Scenario
If a device and a BGP peer specified on the device both support GR, you can run the peer graceful-restart timer wait-for-rib command to set the maximum duration for the device to wait for the End-of-RIB flag from the peer. After the BGP session between the device and the peer is reestablished, if the device does not receive the End-of-RIB flag within the specified duration, the BGP session on the device exits from the GR process and the device selects the optimal route among reachable routes.
