Usage
The area range command is used to summarize intra-area routes for an area. The single summary route is then advertised to other
areas by the Area Border Routers (ABRs). Routing information is condensed at area boundaries and outside the area. If the
network numbers in an area are assigned in a way such that they are contiguous, the ABRs can be configured to advertise a
summary route that covers all the individual networks within the area that fall into the specified range.
Examples
ospfd# configure terminal
ospfd(config)# router ospf 100
ospfd(config-router)# area 1 range 192.16.0.0/24
