D-Link DES-3326S Layer 3 Switch
Area Aggregation Configuration
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 the 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 configure OSPF Area Aggregation on the switch, click the
Area Aggregation Configuration
link in the OSPF folder:
