## Configure an NSSA Translation Role

You can configure the translation role for an NSSA to ensure that Type-7 LSAs are always translated into Type-5 LSAs. Alternatively, the default setting simply identifies an NSSA border router as a candidate that can participate in the translator election process.

This example configures area `0.0.0.6` as an NSSA in SEFOS1 (router ID `10.0.0.1`) and specifies that the border router will always be able to translate Type-7 LSAs into Type-5 LSAs.

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 translator role.

       SEFOS(config-router)# area 0.0.0.6 translation-role always

7. Ensure that the translation role is correct.

       SEFOS# show ipv6 ospf areas
