Inaki, what vendor, which switch? Do you have a URL for us? I still wonder: what is layer 2 PBR? What are its uses? How does it function? Can you give us a good example, or point us to a web site/document with a good example? We've heard a lot of speculation, originated by some people who were wondering themselves if such a thing was possible, used by anyone, and what uses they were making of it. So far, you are the only one to answer the original question! (other than me speculating that it is not possible, nobody is using it, and asking if anyone knows better.) Glad you spoke up! --p -----Original Message----- From: firewall-wizards-bounces () listserv icsalabs com [mailto:firewall-wizards-bounces () listserv icsalabs com]On Behalf Of Iñaki Arenaza Sent: Saturday, April 05, 2008 3:38 PM To: firewall-wizards () listserv icsalabs com Subject: [fw-wiz] Layer 2 (stealth) firewalls - PBR?

They usually deal with some Layer 2 protocols (use in special industrial environments), and they want to control where those Layer 2 packets go (output port) depending on several factors like being unicast/multicast/broadcast, coming/going to certain MAC addresses/addresses groups, etc. So while not widely used, there are people doing 'crazy' stuff like that.
