D-Link DES-3326SR [191/240] Area aggregation configuration

D-Link DES-3326SR 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:
