graceful-restart
Enables graceful or hitless restart and configures the required parameters for the restart process.

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 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
Supported
Releases
10.3.0E or later

Parameters
● template-name — Enter a template name. A maximum of 16 characters.
● inherit-type {ibgp | ebgp} —To associate a template to an unnumbered peer, specify the
inherit-type. The options are ibgp and ebgp.
Default Not configured
Command Mode ROUTER-NEIGHBOR
Usage
Information
