[c-nsp] 4431 - L2TPV3 xconnect inside Service Instance

[Richard Clayton]

I actually got VXLAN working between 2 x 4431s in the end, regardless of
what the Cisco site said.  I guess what they mean is, "it will work on the
4431 but we will not support it".  It's actually a cool protocol/feature,
works well and fails over fast.
