Long,
Look at your routes again on R3. Determine which routes R3 has selected as it's best path (*>), then look at what the next hop is. From your list, I see only two routes coming from 204.12.1.254 which I'm guessing is from R3's eBGP connection to a backbone. R3 will advertise these to R5. Now look at your other best routes, most of them have a next hop of 54.1.1.254. If R3 is receiving these routes from R5, will he advertise them back to R5? Do this, sho ip bgp neighbor x.x.x.x (Ip address of R5) received-routes, to verify which routes you're receiving from R5. Also, for fun, shut the bgp peering session between R6 and the backbone router, then see how many routes R3 is advertising to R5.
