[f-nsp] Redundant routes

[George B.]

The customer might have some kind of loop in their network and when
you shut down one interface, it allowed the loop to clear.  I don't
see anything wrong with your config but generally I like to use
different vlans for things like that just to prevent layer2 loops
though any of my stuff.

What I do is put the ports in separate vlans that have only  that one
port in them (yeah, I know that gets expensive if you have a lot of
customer handoffs) and turn spanning tree off on the ports,
