^100$ means that it's from AS100 and there aren't any transit AS's in
between. The ^ signifies the beginning and $ signifies the end. If your
AS path began at 100 but also included another AS, it would not match
this string.
You would usually use this if you have a directly attached AS and you
only want updates from it, and not the other AS's attached to it.
