I am new to OSPF.Can somebody tell me how OSPF multiple area concept works. As per the theory, multiple areas wont be having identical database. Each area will have a locally significant database giving more importance for local area networks. But when I connected 2 areas( say 1, 2) and connected them using area 0 I can see the routes of area 1 in area 2 . How is this possible? Will the area continue to have the routes of the other areas, but only difference is in LSA received ?
Thanks in Advance
