View
Route policy view
Parameter
as-path-number: AS path number, ranging from 1 to 199.
Description
Use the if-match as-path command to match the AS path field of BGP routing
information.
Use the undo if-match as-path command to cancel the AS path field matching.
By default, AS regular expression is not set for matching in Route-policy.
An if-match statement of Route-policy sets AS path attributes as matching conditions
to filter BGP routing information.
Example
# Create as-path 2, which permits the routing information of AS 200 and AS 300. Then
create a Route-policy named test, and define an if-match statement quoting the
definitions of as-path 2 for node 10 of the Route-policy.
