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

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

ibgp-ecmp-next-hop-self

Configures the ECMP routes to be advertised to an iBGP peer with next-hop-self.

Syntax

[no] ibgp-ecmp-next-hop-self
