[c-nsp] Dual Homed Site with L2 Backup

[Richard Clayton]

Hi Arie

I did encounter the MTU requirement and configured the lab to allow for
it.  VXLAN may be the future but this topology isn't really what it was
intended for, due to the loop it creates (same with OTV).  I was still able
to ceate a working design for both protocols regardless.

Would interesting to see how others would meet the requirement with this
particular set of constraints.

Thanks
Rick
