I set up a vpls tunnel from AC1 to Core, but only on Core, the vpls interface is running.
Nothing happens on AC1, not running, no traffic over vpls.

I already tried different peer settings in VPLS (lsr-id, interface ip)

Is there any configuration issue in my network?

Re: VPLS Problem - Peer1 vpls running, peer2 not

Tue Apr 05, 2011 3:35 pm

Have you ever managed to find the cause of the problem / solution?

I have pretty much the same situation and I cannot find a fix. I have a couple of MT's running v.3.30 and the other ones running v.4.x. LDP and MPLS are OK, but i get VPLS running on just one side.

I disabled all filtering in firewall, but I get still the same: one side is running the other one is not.

Let me know if you found a solution and if you can pinpoint me to a solution

Tnx!

Got it solved.
For all of you having the same problem, set MPLS-MTU to specific interface ... not to all.
That solves the problem
