If you are not sure what address ranges to consolidate, first enable

external route redistribution via the Redistribute configuration screen,

view the routes imported into the routing table, and then configure one

or more summary addresses to reduce the size of the routing table and

consolidate these external routes for advertising into the local domain.

To summarize routes sent between OSPF areas, use the Area Range

Configuration screen (
