I would contend that you would use 100$ as your regexp.
^ implies the beginning of the string so you would be looking for "100 ...."
Instead of ".... 100"

If the requirement is to match prefixes originated from AS 100 and after
looking at the routing table the only ones that originate in 100 get
directly sent to your AS. So a regexp of ^100$ would catch all
prefixes. So as a a best lab practice, Should I use this regexp or make
sure I cover the case of ASpath 500 400 100. It meets the requirement
to match b/c it originated in 100 but the regexp wont catch it. Would
proctors inject certain things into backbone routers while grading?
