NETGEAR 8800 Chassis Switch CLI Manual Note: For BGP graceful restart to inter-operate with Cisco routers, any restarting routers connected to Cisco routers must be configured with the command, enable bgp neighbor capability, in the following form, enable bgp neighbor capability ipv4-unicast. The command must be executed before BGP is enabled globally on the switch. Example The following command configures a router to add IPv4 unicast addresses to graceful BGP restarts: configure bgp restart add address-family ipv4-unicast configure bgp restart restart-time configure bgp restart restart-time Description Configures the restart time used with graceful BGP restart. This is the maximum time a receiver router waits for a restarting router to come back up. Syntax Description seconds Specifies the restart time. The range is 1 to 3600 seconds. Default The default is 120 seconds Usage Guidelines This command configures the restart timer. This timer is started on the receiver router when it detects the neighbor router is restarting (usually when the peer TCP session is reset). At that time, routes from the restarting router are marked as stale, but are preserved in the routing table. The timer is stopped when the restarting BGP neighbor goes to the ESTABLISHED state (it has finished restarting). If the timer expires, the stale routes are deleted. Example The following command configures the graceful BGP restart timer: configure bgp restart restart-time 200 1118 | Chapter 25. BGP Commands
