CLI Reference Guide

bgp router-id

Use this command to configure a fixed router ID for the Border Gateway Protocol

(BGP) routing process. Use the no form of this command to remove the fixed

router ID from the running configuration file.

bgp router-id IP-ADDRESS

no bgp router-id [IP-ADDRESS]

Default THe local router ID is selected by the following rules:

If a loopback interface is configured, the router ID is set to the IP address of the

loopback. If multiple loopback interfaces are configured, the loopback with the

highest IP address is used.

If no loopback interface is configured, the router ID is set to the highest IP

address on a physical interface.

Command Mode Router configuration.

Address family configuration.

Usage Guideline The bgp router-id command is used to configure a fixed router ID for a BGP

routing.

The address of a loopback interface is preferred to an IP address on a physical

interface because the loopback interface is more effective than a fixed interface

as an identifier because there is no physical link to go down.

A unique router ID must be specified within the network.

This command will reset all active BGP peering sessions.

It is recommended to configure a loopback interface, since the physical interface

link may be up/down/removed for some reason.

Example This example shows how to change the router ID with 192.168.1.1

Syntax Description
