-> Depends on what your goals are. What do you want to achieve -> using BGP on these routers? Do you want the Branch A router -> to learn all the routes from Branch B and HQ and do path -> selection on its own? Should Branch B simply default route -> to Branch B and HQ and let those routers make the outbound -> transit decision? Do you want to prefer one exit path vs another? -> ...etc...etc...

I want router A to learn everything from both routers and do the path selection. The main concern right now is routes from the Exchange point are sent to Branch A from both branch B and the HQ. Both HQ and Branch B need to send a default route to Branch A because some routes to the larger internet are not on their routing tables.

So far the best way seems to be establishing two route reflectors at Branch B and the HQ this is especially going to be important if I ever need to connect other BGP speaking routers in the future.
