[c-nsp] OSPF design (danger will)

[Keegan Holley]

Correct me if I'm wrong but I thought you also needed an IGP in order to use
traffic engineering features.  It I've never heard of mpls with BGP only in
a large network.  I have heard of running BGP only on the PE routers for
simplicity and running ospf everywhere else just to form the LSP's.
