Functional Notes
This command sets the administrative distance for BGP routes. The administrative distance is a local
variable that allows a router to choose the best route when there are multiple paths to the same network.
Routes with smaller administrative distances are favored.
Usage Examples
The following example gives external BGP routes an administrative distance of 30, internal BGP routes an
administrative distance of 200, and local routes an administrative distance of 240:
(config)#router bgp 1
(config-bgp)#distance bgp 30 200 240
