Specifies whether or not an NSSA border router will unconditionally translate
Type-7 LSAs into Type-5 LSAs. When set to always, an NSSA border router always
translates Type-7 LSAs into Type-5 LSAs regardless of the translator state of
other NSSA border routers. When set to candidate, an NSSA border router participates
in the translator election process. For non-NSSA border routers, this value is none.
