Configure the Stability Interval for NSSA

The stability interval is used when an elected translator determines that its services are no longer required and the translator continues its translation duties for additional time.

This example configures area 0.0.0.6 to be an NSSA with the stability interval set to 120 seconds.

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 the ASBR router status.

   SEFOS(config-router)# asbr router
   

5. Configure an area as an NSSA.

   SEFOS(config-router)# area 0.0.0.6 nssa
   

6. Configure the stability interval for the NSSA area.

   SEFOS(config-router)# area 0.0.0.6 stability-interval 120
   

7. Ensure that the stability interval is correct.

   SEFOS# show ipv6 ospf areas
