Hi All

Need some help on Regex.

I want to permit route originated only from AS 2025 only. I am using the
Regex in the filter list as _2025$, which means the first AS is 2025, I have
a bit, confusion will this match all routes generating from AS 12025,
22025, 32025............ also. or only routes generating from AS 2025.

Coz as per DOC CD "_" means match anything before the digit. So does it mean
match only the AS before the given AS or it can prepend any number of
digits in the given AS also........

Regards
Sachin
