Configure the Stability Interval for NSSA

This procedure configures the number of seconds after which an elected translator determines that its services are no longer required, and that it must continue to perform its translation duties for NSSA.

  1. Enter Global Configuration mode in SEFOS1.
    SEFOS# configure terminal
  2. Enable OSPF globally in the switch SEFOS1.
    SEFOS(config)# router ospf
  3. Configure the OSPF router ID.
    SEFOS(config-router)# router-id 10.10.2.1
  4. Configure the ASBR router status.
    SEFOS(config-router)# asbr router
  5. Configure the OSPF interface.
    SEFOS(config-router)# network 10.10.2.1 area 0.0.0.6
  6. Configure the area 0.0.0.6 as an NSSA area.
    SEFOS(config-router)# area 0.0.0.6 nssa
  7. Configure the stability interval for the NSSA area 0.0.0.6 as 120 seconds.
    SEFOS(config-router)# area 0.0.0.6 stability-interval 120
  8. Configure the default stability interval for the NSSA area 0.0.0.6.
    SEFOS(config-router)# no area 0.0.0.6 stability-interval

    Note - The default value for stability-interval is 40 seconds and is configured using the command no area area-id stability-interval.
