Command Reference Guide
as-path-list <name>
Use the as-path-list command to assign a predefined autonomous system (AS) path list to a Border
Gateway Protocol (BGP) Internet Protocol version 4 (IPv4) or Internet Protocol version 6 (IPv6) address
family (AF) neighbor. This list is then used to filter inbound and/or outbound BGP route updates. This
command can be used for a BGP AF neighbor on either the default or nondefault VPN routing and
forwarding (VRF) instance. Use the no form of this command to discontinue use of the list. Variations of
this command include:
as-path-list <name> in
as-path-list <name> out
Syntax Description
<name>
in
out
Default Values
By default, no AS path lists are specified for filtering.

Functional Notes
The as-path-list command can be used to specify the AS path list for a BGP AF neighbor on either the
default or nondefault VRF instance. If the AF neighbor is to be created on a nondefault VRF instance, the
VRF instance must first be created using the command
Once you have created the nondefault VRF instance, you can configure the BGP AF neighbor settings for
the VRF instance using the command
mode. For example, to configure the IPv4 BGP AF neighbor characteristics for the nondefault VRF
instance RED1, enter the following commands:
(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)#neighbor 10.20.1.1
(config-bgp-vrf-ipv4-neighbor)#
