Given that you assign unique RD per PE, RR out of the
forwarding path provides you with a neat trick for fast
convergence (and debugging purposes) when CE has
redundant paths to different PEs. Routes to those CEs
will be seen as different routes on RR.

Not having to dump routes into FIB *really* speeds up 
convergence. It's not even funny :-)...
