[c-nsp] CsC IOS XR

[Darren O'Connor]

What does your MPLS config look like? You need /32 static routes on XR for labelled next-hops in certain cases as it's not automatic. 

In your topology, what is the customer PE and provider PEs? Does the XR box have a valid labelled next-hop to the correct PE?

Thanks
