When the NSSA border router is acting as a translator it sets the Nt bit in router
LSAs it originates into the NSSA.
An elected translator loses its translator role when another NSSA border router
with a higher router identifier is elected as translator or an NSSA router
configured to always translate gains border router status. When an elected
translator loses its translator role, it continues to translate Type-7 LSAs for an
additional period of time set by the nssastability parameter. This allows a
more stable transition to the newly elected translator and minimises excessive
flushing of translated Type-7 LSAs.
The nssatranslator and nssastability parameters are only valid when stubarea
is set to nssa.
You can display the current translator role for an area using the command:
show ospf area=area-number
You can display the current translator role for all areas using the command:
show ospf area full
