[c-nsp] MPLS router-ID

[Mohammad Khalil]

Thanks Nick/James for the replies
Yes , I mean MPLS LDP router-id
I understand the simplicity of inter-as VPN options and I wish it was the case 
They requested BGP in order for future VPLS connections as well 
We are using BGP at the moment as we are advertising the router-ids (public loopbacks) and am sure we can replace that via static

What is werid for me till now , why the session is passive 
Meanwhile , I have tested it on Cisco and worked like a charm 

BR,
Mohammad
