Richard, You have a very valid point and to be honest we never found out - ironically this morning we lost a transit connection which is on a different EX4200 switch and I'm investigating a potentially similar MAC issue. I'm not sure yet but I've asked the upstream for detailed MAC information to see if it could be related.
If I find something concrete I'll be happy to share this back with the list - was hoping to find someone who had already deployed EX4200's towards exchange points possibly ... so I could see if they ran into any of this (which we're presuming most of it is just us learning more about Juniper) :) Paul -----Original Message----- From: Richard A Steenbergen [mailto:r...@e-gerbil.net] Sent: March-25-10 8:41 PM To: Paul Stewart Cc: 'jnsp' Subject: Re: [j-nsp] EX Switches - Internet Exchange Points On Thu, Mar 25, 2010 at 08:01:36PM -0400, Paul Stewart wrote: > Thanks Richard... > > The MAC filtering idea proposed earlier by another friendly person was > quite helpful and solved the issue.

The MAC filter is a fine workaround, but if your EX's are leaking things they shouldn't be I'd like to see that get addressed too. :) -- Richard A Steenbergen <r...@e-gerbil.net> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC) _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
