Multiple area router configuration commands specifying the range option can be configured. Thus,
OSPF can summarize addresses for many different sets of address ranges.


Examples

The following example specifies one summary route to be advertised by the ABR to other areas for all
subnets on network 10.0.0.0 and for all hosts on network 192.168.110.0:
interface eth-0-1
ip address 192.168.110.201/24
!
interface eth-0-2
ip address 192.168.120.201/24
!
router ospf 201
network 192.168.110.0/24 area 0
area 10.0.0.0 range 10.0.0.0/8
area 0 range 192.168.110.0 255.255.0.0
