NOTE:
For OSPF to function properly some settings should be identical on all
participating OSPF devices. 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. A new window (pictured below) appears. To change an existing configuration, click on
the corresponding
Modify
button for the set you want to change. The window to modify an existing configuration is the same as
the window used to add a new one.
