Hello:
Can i get some input on the accuracy of the following regurlar
expressions, please?
Going to network that were origionated in AS 54
ip as-path access-list 1 permit _54$
because, the origion of the route should be the end of the as-list
Here 54 is the origion of 100 200 300 400 54.
Going to networks outside of AS 54
ip as-path access-list 2 permit _54 +
because this list matches one or more instances of an AS that exists
outside of AS-54.
this list will match someting like 100 54 200 300, or 54 100 My reference
