acl-number: AS path ACL number, in the range of 1 to 199.
export: Filters the advertised routes.
Description
Use the peer as-path-acl export command to configure filtering policy of BGP
advertised routes based on AS path list.
Use the undo peer as-path-acl command to cancel the existing configuration.
By default, no AS path ACL is configured for a peer group.
You can use the peer as-path-acl export command on a peer group. In the peer
as-path-acl export command, the acl-number argument is the AS path list number. It is
configured by using the ip as-path-acl command, instead of the acl command.
Related commands: peer as-path-acl import, ip as-path-acl.
Examples
# Filter routes exported to the peer group (named test) based on AS path ACL 1.
