BGP ROUTER ID

bgp router-id

Overview Use this command to configure the router identifier. The IPv4 address specified in
this command does not have to be an IPv4 address that is configured on any of the
interfaces on the device. Note that you must specify an IPv4 address with this when
used for BGP4+.
Use the no variant of this command to return the router-id to its default value (as
described in Default below).
bgp router-id <routerid>
Syntax
no bgp router-id [<routerid>]
Default If the BGP router ID is not specified, the IPv4 address of the loopback interface is
used. When there is no address on the loopback interface, the highest IP address
among the VLAN interfaces is used. Note that devices that have an Ethernet
management interface will not use that eth interface's IP address as a router ID.
Mode [BGP] Router Configuration or IPv4 Address Family Configuration
Mode [BGP4+] Router Configuration
