I want router A to learn everything from both routers and do the path selection.

Not sure I understand what you mean by 'everyting'. Do you mean full Internet routes, partial routes, whatever B and HQ have, IXP routes, e.t.c.?

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.

Okay, is this the way you have designed it, that you only have partial routes in B and HQ, or is this the problem you are trying to solve? What exactly do you need B and HQ to send to A?

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.

RR's are good, and it's great you're planning ahead, but it's still not clear what it is exactly you want out of A; unless I missed something.

The other thing, if A, B and HQ are all in your AS, why have you chosen to use private ASN's internally, yet you already have a public (12455) ASN?

Are you running any intelligent IGP, e.g., OSPF?
