[c-nsp] EoMPLS between 7600 & 7200 config clarification

[Justin Shore]

Bill,

I'm in a similar boat as Jose.  What options for EoMPLS do we people 
with 6700s have?  I'm trying physical to physical with no luck. 
Sub-interface isn't an option for a particular design that I'm working 
on either.

Thanks
  Justin
