BGP Configuration Commands 525
By default, the peer group has no AS path list.
This command can only be configured on the peer group. The acl-number
specifies the number of the AS path list. It is configured by the ip as-path-acl
command rather than the acl command.
Related command: peer as-path-acl import, ip as-path-acl.
Example
# Configure to filter the routes advertised by the peer group test using the AS
path-list 1.
[3Com-bgp] peer test as-path-acl 1 export
peer as-path-acl import Syntax
peer { group-name | peer-address } as-path-acl acl-number import
undo peer { group-name | peer-address } as-path-acl acl-number import

Description
Use the peer as-path-acl import command to configure filtering policy of BGP
received routes based on AS path list.

configured for the peer group.
