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.
To aggregate routing information contained within an OSPF area, highlight Area Aggregation
Configuration from the Setup OSPF menu and press Enter.
The following fields can be set:
