For more information about VRF and Multi-VRF BGP configuration, refer to the configuration guides
Configuring IPv4 Multi-VRF in AOS (article number 2156) and Configuring BGP in AOS for Releases

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 lower administrative distances are preferable.
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 for the IPv4 BGP AF on
the default VRF instance:
(config)#router bgp 100
(config-bgp)#address-family ipv4
(config-bgp-ipv4)#distance bgp 30 200 240
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 for the IPv4 BGP AF on
the nondefault VRF instance named RED1:
(config)#vrf RED1 route-distinguisher ip 192.17.250.24:33
(config)#router bgp 100
(config-bgp)#vrf RED1
(config-bgp-vrf)#address-family ipv4
(config-bgp-vrf-ipv4)#distance bgp 30 200 240
