question.........
if you wanted an as-path expression to account for an AS with a connected
neighbor and with any amount of additional hops - i.e. 54 100 200 236
2 what would that expression be?

i know that to get directly connected to AS 54 it would be ^54_[0-9]*$, but
what if you wanted to account for any number of additional hops <AS's>
weather they exist or not <zero or more>?

thanks!!
