QinQ EoMPLS

Unanswered Question
Nov 9th, 2009

I have a SUP720(port based mpls) and a SUP2 (SVI based mpls.) I can get the VC to come up if I wanted to do one vlan accross my network.

I am having issues getting a port to trunk across my EoMPLS to a 7200 router.

Currently, I have a Flex-wan module for the SUP2 side, which supports this, but I am getting different views based off the QinQ.

Any ideas?

I have this problem too.

Hi,

Have you tried changing the MTU sizes to 9216?

Also, what do you mean by "but I am getting different views based off the QinQ."?

No I kept the MTU at 1500.

What I mean by that is that it seems everyone is doing it slightly different from another.

I've been all over Cisco's site and I cannot find any clear definite way that other engineers are setting this up.

Also, it seems that this topic is considered part of two different departments at Cisco, so not one department is able to go over the entire setup because they either know MPLS or they know dot1q.

I just wish there was a document that was like, "this is what you need to do this."
