I get it from this Groupstudy ..
Regular Expressions:
^200$
Match only AS
200
^*
Match all ASs
^$
Local AS only
^200_
Match strings
received from AS 200
_200$
Match strings
originating from AS 200
_200_
Match strings
which include AS 200
^200_210$
Match strings
received from 200 AND
originating
from 210
My understanding is you use "^" if the originating AS directly connected AS
and use "_" if there could be other AS's in the path. Let's say the
originating AS is 777, then
^777$ means directly from 777 however
_777$ could be the following
777
100 777
200 100 777
200 300 400 777 etc meaning it originated from xxx but could also be other
AS in the path.
