[c-nsp] Jumbo frames, MPLS, and Metro Ethernet

[F. David Sinn]

Keep in mind failures.  I had one incident where a provider had not 
accounted for FRR causing a double label encapsulation resulting in my 
path transparently failing over, but dropping my max MTU by the cost of 
a label.  So depending on your engineering decisions, you may need to 
support more then a single label, or suffer the consequences.
