[j-nsp] reusing loopback 0 ip address in vrfs

[Sean Clarke]

I would say common practice - if you're using VRF's in a multivendor 
environment with draft-rosen for instance, I believe you MUST use the 
same IP address in the lo0.x interface, as the "other" vendor expects 
the lo0.0 address (which the Juniper won't send). Of course all Juniper 
network won't have that issue and you're free to choose.
