Configure the Metric Type for an NSSA

If default summary routes are selected, you can configure the metric type for the default summary route that is sent to an NSSA.

This example configures the IP address 0.0.0.6 as an NSSA in SEFOS1 (router ID 10.0.0.1) and specifies that the metric type for the NSSA is Type-2 external cost (value 3).

1. Enter Global Configuration mode in SEFOS1.

   SEFOS# configure terminal
   

2. Enable OSPF globally in SEFOS1.

   SEFOS(config)# ipv6 router ospf
   

3. Configure the OSPF router ID.

   SEFOS(config-router)# router-id 10.0.0.1
   

4. Configure an area as an NSSA.

   SEFOS(config-router)# area 0.0.0.6 nssa
   

5. Configure the metric type as Type-2 external cost (value 3).

   SEFOS(config-router)# area 0.0.0.6 default-metric type 3
   SEFOS(config-router)# exit
   

6. Ensure that the correct metric type is set.

   SEFOS# show ipv6 ospf areas
