[c-nsp] as-path access-list question

[Tom Sands]

First using an * like this also matches ^6539$  when doing ^6539_[0-9]*$
I would recommend the + for trying to make the adjustments you are 
looking for.

If you wanted to try something in between maybe do:
^6539$
^6539_[0-5]+$

Basically, matching the prefixes that are connected, and "SOME" ASN's 
that transit 6539 (only if they have values between 0-5)


just a thought..
