[c-nsp] ASR9k to Me3600x VPLS

[Pshem Kowalczyk]

Hi,

I hope that collective knowledge can help me here.
We're trying to build a simple VPLS between an ASR9k (IOS XR 4.2.3)
and ME3600x (IOS 15.3(1)S) using BGP autodiscovery and LDP for
signaling.

THe VPLS is not coming up,as the pseudowires are not up, I've located
the issue to the control word - the 9k runs with 'disabled' whilst the
ME3600x runs on autosense and that is failing as it results on
'control word on':

ME3600X:

Does anyone have it going between the 9k and ME3600x?
