● receiver-only — Local router supports graceful restart as a receiver only
Defaults Disabled
Command Mode ROUTER BGP
Usage
Information
When you enable graceful restart on a node, its BGP neighbor acts as a helper by not dropping the
sessions and maintaining the route information so that the traffic is not disturbed. The no version of this
command disables graceful-restart helper mode.
NOTE: To configure these settings for a non-default VRF instance, you must first enter ROUTER-
CONFIG-VRF sub mode using the following commands:
1. Enter the ROUTER BGP mode using the router bgp as-number command.
2. From the ROUTER BGP mode, enter the ROUTER BGP VRF mode using the vrf vrf-name
command.
Example
OS10(conf-router-bgp-10)# graceful-restart role receiver-only
