[j-nsp] Merging two OSPF area

The more important question is IP address space.  Is there conflicting IP
space at the two companies?  If so how can it be addressed?  If the
addresses can't be changed this pretty much guarantees that the topologies
will not merge.  If that's the case the choice of protocol BGP or ospf at
the edge really depends on the size of the tables.  BGP is more flexible but
it doesn't matter if you only have 50 routes.

If you can merge completely, I would just work on migrating the network to a
single ospf topology a few routers at a time.  Again what you do at the
edges during the interim depends on the size of the network and the exact
topology.
