Task asks us to have R3 originate a default route into OSPF as long as it has an active connection to either BB2 or BB3. The solutions guide used a route-map which checked for the presence of the networks that BB2's or BB3's directly connected interface to R3 reside in as a means of determining whether the BBs would be accessible. What doesn't make sense is if I shutdown the BGP session between R3 (not the interface) and it's neighbors, the default route still gets originated. Correct me if I'm wrong, but the solution doesn't meet the task requirements.
The way I got this to work was to configure my prefix list to permit the BGP routes received from BB2 and BB3. Then, when I shutdown my BGP neighbors, all my BGP routes went away as did the default route. As soon as I added one of my BGP neighbors back, the default route came back as well. Also, I was able to get this to work whether I was using "default-information originate always" or just "default-information originate".
