[j-nsp] Problem with an lt- interface

[Sailendra Mahanty]

Hi Mircho,

I think it's the same issue that i was referring (when you see 
interfaces going down when added to instance).

You can always send me the detailed config for having a look, but i 
guess JTAC would be able to support you more then me.

Did you see the interface up before activating the L2VPN instance (may 
be you can just delete the pair of lt interfaces units and recreate) ?

thanks,
