graceful-restart
Enables graceful or hitless restart and congures the required parameters for the restart process.
Syntax
graceful-restart role receiver-only
Parameters
• role — Sets the restart role of the local router
• 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 trac is not disturbed. The no version of this command disables
graceful-restart helper mode.
NOTE: To congure these settings for a non-default VRF instance, you must rst 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
