[c-nsp] T1 to Ethernet Tunnel

[David Freedman]

Agree with Alex, L3VPN can be suitable for certain types of customers 
who request L2 service, when you speak to them and work out what they 
"actually" need.

A subject of contention here can be if you propogate customer IP TTL 
into MPLS shim and hence allow your P routers to issue TTL exceed 
messages back to the C/CE routers , in such case, with cisco you can 
only disable this behaviour wholly at each PE and not selectively which 
has been one of my long standing rants.
