Filter on an AS-Path attribute
The BGP attribute, AS_PATH, can be used to manipulate routing policies. The AS_PATH attribute
contains a sequence of AS numbers representing the route's path. As the route traverses an Autonomous
System, the AS number is prepended to the route. You can manipulate routes based on their AS_PATH to
affect interdomain routing. By identifying certain AS numbers in the AS_PATH, you can permit or deny
routes based on the number in its AS_PATH.
To view all BGP path attributes in the BGP database, use the
Privilege mode

AS-PATH ACLs use regular expressions to search AS_PATH values. AS-PATH ACLs have an "implicit
deny." This means that routes that do not meet a deny or match filter are dropped.
