I am going to take a "stab" at this one. IT seems to me that the only
routes that are being advertised from within area 3 are the directly
connected routes on s0/s1. Try to create additional loopback interfaces
on the other routers in area 3 (RIDs 172.16.20.1 and 172.16.30.1), make
sure they are placed in area 3 and look at the routing table on router a
and they should be there.
