Usage Guidelines

Usage Scenario

To set the maximum duration for a BGP restarter to wait for the End-of-RIB flag from each peer, run the graceful-restart timer wait-for-rib command. After the BGP session between the BGP restarter and any peer is reestablished, if the BGP restarter does not receive the End-of-RIB flag from this peer 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 graceful-restart timer wait-for-rib command is run more than once, the latest configuration overrides the previous one.

Precautions

If there are a large number of routes, setting time to a large value is recommended.

Example

# Set the maximum duration to 100s for a BGP restarter to wait for the End-of-RIB flag from each peer.
