Thx. I did not paly with all that different strings but nice to know. :-)
So in short "*" can include space in AS path string i.e. "_" and it covers "any multiples" too. thanks Date: Mon, 23 Nov 2009 09:57:43 -0700 Subject: Re: [OSL | CCIE_RS] Core Knowledge Quizzer Question 38 : BGP From: bbar...@ipexpert.com To: patelpr...@hotmail.com CC: lucho.ort...@usa.net; ccie_rs@onlinestudylist.com FWIW, If you only wanted one AS in the middle it could be something like this: AS#_[0-9]+_AS# On Mon, Nov 23, 2009 at 8:59 AM, pra pa <patelpr...@hotmail.com> wrote: Thx, I did not test it.
