View
Routing policy view
Parameter
acl-number: AS path list number. The range is 1 to 199.
Description
Using the if-match as-path command, you can configure the matched AS path list
number of route-policy. Using the undo if-match as-path command, you can
cancel the matched path list number.
By default, AS path list number is not matched.
This if-match clause of route-policy is used to filter BGP routing information. The
match condition is specified according to the AS path attributes of the routing
information.
Example
Define an as-path numbered as 2 and allow the autonomous system number to
contain the routing information of 200 and 300. Then, define a route-policy
named test. The node No.10 of this route-policy defines a if-match clause, which
quotes the definition of as-path.
[3Com] ip as-path acl 2 permit 200:300
[3Com] route-policy test permit node 10
[3Com-route-policy] if-match as-path 2
