Hi, I am trying to figure out something. In OSPF, you have different areas, and you have area0 which is the backbone. does area0 know about every route possible in its routing table for the whole network or just its own area, area0. I know they require strict hierarchical network design, so that a network can be broken into smaller areas to reduce the size of the topology tables. I am just asking this because someone was telling me that the DR (designated router) and BDR (backup desiganted router) in area0, which is the backbone, know all of the routes in the whole network, but I am not sure if he is right.
edit: I also think that if it was a very large network and if it knew every single possible route, the router itself would not have enough RAM and processing power to handle such a large routing table.
Anyways thanks if you can help clarify this.
