Information
Change the router ID of a BGP router to reset peer-sessions. The no version of this command resets the
value to the default.
By default, OS10 sets a loopback IP address as the router ID. If there is no loopback address, the software
chooses the highest IP address that is configured to a physical interface.
NOTE: To configure these settings for a nondefault 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)# router-id 10.10.10.40
Supported
Releases
