OSPFV3/3/NSSATRNSLTRSTSCHNG:OID [oid] The status of the NSSA translator has changed. (AreaId=[integer], RouterId=[gauge], State=[integer])
The translator role in the NSSA changed. A possible cause is that the status of the translator changed among Enabled, Elected, and Disabled.

ASE routes may flap for a short period in the following situations. The translator role of the NSSA ABR changes; Type 5 LSAs translated from Type 7 LSAs need to be flushed; or a new translator is translating Type 7 LSAs to Type 5 LSAs. In addition, the translator role changes without manual configuration mostly because the topology in the backbone area or the NSSA changes.
1. The parameter translator-always in the nssa command was manually configured or canceled on an ABR in the NSSA.
2. A new router ID was configured on an ABR in the NSSA and took effect.
3. A new switch joined the NSSA or a switch exited from the NSSA.
4. The OSPFv3 protocol was restarted or the master/slave switchover was performed on a switch in the backbone area or the NSSA. This resulted in topology instability in the NSSA.
5. The nssa command was manually configured or the parameters in the nssa command were manually modified, which caused the topology of the backbone area or the NSSA changes. For example, configuring or canceling the parameter no-summary or no-import-route in the nssa command will lead to the reestablishment of neighbor relationships between the local switch and a switch in the backbone area, and between the local switch and a switch in the NSSA.
6. The role of the local switch changed to an ABR or changed from an ABR to another role.
7. The topology of the backbone area or the NSSA changed. As a result, the local switch cannot reach another ABR with a greater router ID or with the parameter translator-always from the backbone area or the NSSA.
If the nssa translator-always command is configured, run the display ospfv3 area command to check whether the status of the NSSA translator is always. If so, go to Step 8. If not, go to Step 7.
If the configuration of the nssa translator-always command is canceled, run the display ospfv3 area command to check the status of the NSSA translator. If the status is disabled, go to Step 2. If the status is elected, go to Step 8.
If the Router-LSA of a specific ABR carries the N bit or other ABRs are configured with the nssa translator-always command, go to Step 8.
If the Router-LSA of a specific ABR does not carry the N bit or other ABRs are not configured with the nssa translator-always command, go to Step 3.
If so, go to Step 8.
If not, go to Step 4.
If so, go to Step 8.
If not, go to Step 5.
If the router ID of a specific ABR remains unchanged, go to Step 5.
If so, go to Step 8.
If not, go to Step 6.
If a non-ABR joins the NSSA, go to Step 6.
