peer graceful-restart timer wait-for-rib (BGP multi-instance VPN instance IPv4 address family view)

Function

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 Guidelines

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.

Configuration Impact

If the peer graceful-restart timer wait-for-rib command is run more than once, the latest configuration overrides the previous one.

Example

# Set the maximum duration during which a BGP restarter waits for the End-of-RIB flag from a specified peer to 100s.
