Configuring an Address Range for the NSSA
If you want the ABR that connects the NSSA to other areas to summarize the routes in the NSSA before
translating them into Type-5 LSAs and flooding them into the other areas, configure an address range. The ABR
creates an aggregate value based on the address range. The aggregate value becomes the address that the
ABR advertises instead of advertising the individual addresses represented by the aggregate. You can configure
up to 32 ranges in an OSPF area.
USING THE CLI
To configure an address range in NSSA 1.1.1.1, enter the following commands. This example assumes that you
have already configured NSSA 1.1.1.1.
HP9300(config)# router ospf
HP9300(config-ospf-router)# area 1.1.1.1 range 209.157.22.1 255.255.0.0
HP9300(config-ospf-router)# write memory
Syntax: area <num> | <ip-addr> range <ip-addr> <ip-mask>
The <num> | <ip-addr> parameter specifies the area number, which can be in IP address format.
The <ip-addr> parameter following range specifies the IP address portion of the range. The software compares
the address with the significant bits in the mask. All network addresses that match this comparison are
summarized in a single route advertised by the routing switch.
The <ip-mask> parameter specifies the portions of the IP address that a route must contain to be summarized in
the summary route. In the example above, all networks that begin with 209.157 are summarized into a single
route.
