N/A.
When configuring an OSPF area as an NSSA, the translate option should only be used on NSSA border routers, where translation is to be enforced. If translate is not used on any NSSA border router in a NSSA, one of the ABRs for that NSSA is elected to perform translation (as indicated in the NSSA specification). The option should not be used on NSSA internal routers. Doing so inhibits correct operation of the election algorithm.
The following command configures an OSPF area as an NSSA:
configure ospf area 10.1.1.0 nssa summary stub-default-cost 10 translate
