MPLS Multi-vrf and IP Multicast
by devang patel 18 Sep '09

18 Sep '09

Hello All, Any scenario where we are using MPLS between PE-CE when CE is multi-vrf router, any deployment in real word? Carrier supporting carrier CSC is one where you have MPLS between PE-CE link. If PE-CE running MPLS between them then what will be impact on MULTICAST between two site? If PE-CE connectivity is pure IP then i think multicast will work properly right? thanks, Devang Patel

You're seeing these failures on copper?! I've worked in some places with absolute cabling nightmares on the copper side of things in wiring closets but those were all enterprise situations and we still rarely had failures of ports and even less on the wiring itself. I'd never expect there to be frequent copper issues in a colo where you would not have anywhere near the volume of moving cables around that goes on in an enterprise. On the fiber side, your experience still seems high although obviously much easier to damage fiber cables. Perhaps they have a big mess of a fiber plant and have to fish tape new runs through it and like to snag adjacent cables, etc. It can only get worse if that's the problem and they don't clean it up.

You should be able to test the MTU theory by disabling path-mtu-discovery, which will cause MSS to fail back to the minimum 576. -- Richard A Steenbergen <ras(a)e-gerbil.net> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC)
