I am creating a lab and could use a little feedback. Given the following BGP
path info excerpt:
Paths
44 404 4 i
40 4004 4 i
44 405 4 i
4 i
My question will be something like:
"Configure a filter to only accept routes that contain any one instance of
AS 400 through 409 in their paths. Be efficient in the way you choose the
paths."
My current best answer includes the regex: _40._
Other, less "efficient" choices are:
_40[0-9]_
_40[0123456789]_
I'm sure there are plenty of other "less efficient" choices, but my concern
is whether my answer is the best answer according to my question. And does
the question itself make sense to you?
Thanks in advance
