The triggers/edge drop routers don't have to be meshed - just peer the  
triggers with each of the edge drop routers directly, using route- 
reflector-client.  Be sure to implement uRPF at your access edge if at  
all possible so that you get the antispoofing benefits, and if those  
same routers are your edge drop routers, you'll have S/RTBH  
capabilities, not just destination-based.

      History is a great teacher, but it also lies with impunity.
