[c-nsp] Route Reflector Design

[Mike Johnson]

Tim,

Got that, now for a large network would you create a backbone area (OSPF)
for regionalization of routes
and make routers within the region into other areas? Its the underlying IGP
design that makes all the connector nets to POPs available my main concern.

thanx for your help,
