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 you want to change. The menu to modify an existing configuration is
the same as the menu used to add a new one. To eliminate an existing configuration, click the in the
Delete column for the
configuration being removed.
