PIM-SSM for the P Network, because we didn't want two sets of RPs, I felt 
that could get confusing, the fact that everything runs in an optimal tree, 
and 
since we are both the provider and the customer we have enough control 
over the total multicast state.  Also, many of our VRFs don't actaully need 
multicast, they have been created for specific applications or groups of 
application and most don't use multicast, so why turn it on.

However, given an opprtunity to redo things I might go with PIM-BIDIR for 
the P network, the campus network has a very simple and ridgid topology, a 
dual star, that sould work well for PIM-BIDIR.  The dual-star topology 
doesn't 
allow from much optimization anyway.
