Two GSR/12008s are the core routers for the POP.  Each 7507 has an FE to 
each GSR (bumped to a tag mtu of 1540).  The 6509 has 2xGE to each 
12008, bumped to an MTU of 2450 (the best I could get my Engine 2 3GE 
cards to accept).  So it's a two-hop path from 7507 to 7507 or from 7507 
to 6509.  Every router in question shows the two GSRs as LDP neighbors.
