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.
Click Configuration > Layer 3 IP Networking > OSPF > OSPF Area Aggregation Settings link to view the current
settings. There are no aggregation settings configured by default, so there will not be any listed the first accessing the menu.
To add a new
OSPF Area Aggregation setting, click the Add button. A new menu (pictured below) appears. To change
an existing configuration, click on the hyperlinked Area ID for the set to change. The menu to modify an existing

Delete column for the configuration being removed.
