These settings include the Hello Interval and Dead Interval. For networks using authorization for OSPF devices, the Authorization Type and Password or Key used must likewise be identical. OSPF Area Aggregation Settings Area Aggregation allows all of the routing information that may be contained within an area to be aggregated into a summary LSDB advertisement of just the network address and subnet mask. This allows for a reduction in the volume of LSDB advertisement traffic as well as a reduction in the memory overhead in the Switch used to maintain routing tables. There are no aggregation settings configured by default, so there will not be any listed the first accessing the window. To add a new OSPF Area Aggregation setting, click the Add button.
