fast-external-fallover Resets BGP sessions immediately when a link to a directly connected external peer fails. Syntax fast-external-fallover Parameters None Default Not configured Command Mode ROUTER-BGP Usage Information Fast external fall-over terminates the EBGP session immediately after the IP unreachability or link failure is detected. This only applies after you manually reset all existing BGP sessions. For the configuration to take effect, use the clear ip bgp command. The no version of this command disables fast external fallover. NOTE: To configure these settings for a non default VRF instance, you must first enter the 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)# fast-external-fallover Supported Releases 10.3.0E or later graceful-restart Enables graceful or hitless restart and configures the required parameters for the restart process. Syntax Parameters graceful-restart role receiver-only • 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 ROUTERCONFIG-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 inherit template Configures a peer group template name that the neighbors use to inherit peer-group configuration. Syntax Parameters inherit template template-name • template-name - Enter a template name. A maximum of 16 characters. 608 Layer 3
