Subject: Regular Expressions ( Match on Prepended routes )
Dear All,
Suppose you have the following scenario:
As 300 --- AS 100 ---- AS 400
You control AS 300 and asked to match on routes received from AS 100 and its
customers taking into consideration if any one of them prepended his routes
before sending it.
What would the regular expression look like ?
Thanks for your input.
Yasser
