[j-nsp] Policy option for advertising full routes

[Doug Marschke]

If you do a show route receive-protocol bgp all <neighbor> you will see all
routes that are hidden due to next hop issues or import filtering.  If they
don't show up there, there are being dropped due to AS-Path loops.

The peer is receiving exactly zero routes as confirmed by a  
received-routes command on their router. As I understand it,  
received-routes are the number of routes being received prior to  
filtering. Please advice.
