It seems that trading off the work that a PE has to do to parse the
routes that have been sourced by itself needs to be weighed against the
added complexity and additional work a RR must do to ensure that it does
not send the routes back to said PE. I would guess that the RR would
need to maintain multiple data structures associated with each client
peer, have multiple update groups etc... The main point is which network
device should do the work? My approach has always been to minimize the
work on the RR as it is most important to the viability of the entire
service/network.. The RR infrastructure is more critical and important
than any single PE...

Unless implementations change their behavior to support this,
which is why I keep associating it.  But yes, in general, I
agree.

Agreed..
