[j-nsp] routing-instance interfaces

[Nelson, Brian]

I'm setting up multiple routing-instances for multiple customers. Routing-instance configuration uses the same interfaces in multiple places in the routing-instance config; and I am looking for block substitution method. I don't see groups as an effective way to minimize errors.
Suggestions would be appreciated.
