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.
