Autonomous System Filter Path
Note: The aspath filter is applicable only to the routes that traverse the autonomous system and not to the routes in the AS. The local AS routes are not distributed, even when we define rmap's aspath to permit the routes with local. An explicit route map for the AS routes is needed, as well as an implicit route map for local AS.
For example, to deny prefixes which are received from AS 300, define two route maps and add to corresponding bgp peer, as follows:
 
/c/l3/rmap 1
ena
/c/l3/rmap 1/aspath 1
as 300
action deny
ena
/c/l3/rmap 2
ena
/c/l3 /peer 1
ena
addr 1.1.1.33
ras 100
hold 65535
addo 1
addo 2
The first rmap denies the routes that are from AS 300, and the second rmap allows all routes in this AS.
