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.
| Parameter | Description | Value |
|---|---|---|
| ipv4-address |
Specifies the IPv4 address of a BGP peer. |
The value is in dotted decimal notation. |
| time-value |
Specifies the maximum duration for a BGP restarter to wait for the End-of-RIB flag. |
The value is an integer ranging from 3 to 3000, in seconds. |
| ipv6-address |
Specifies the IPv6 address of a BGP peer. |
The value is a 32-digit hexadecimal number, in the format of X:X:X:X:X:X:X:X. |
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.
