What translates Type 7 LSAs to Type 5 LSAs?

You have two ABRs in the same NSSA area. What translates Type 7 LSAs to Type 5 LSAs?

A.
The ABR with the highest RID.

B.
The ABR with the lowest RID.

C.
Both ABRs will translate.

D.
The ABR configured with the area-range statement.

Explanation:
Translating Type-7 LSAs Into Type-5 LSAs

This step is performed as part of the NSSA’s Dijkstra calculation after type-5 and type-7 routes have been calculated. If the calculating router is not an area border router this translation algorithm should be skipped. All reachable area border routers in the NSSA should now be examined noting the one with the highest router ID. If this router has the highest router ID, it will be the one translating type-7 LSAs into type-5 LSAs for the NSSA, otherwise the translation algorithm should not be performed.

Type 7 – Routers in a Not-so-stubby-area (NSSA) do not receive external LSAs from Area Border Routers, but are allowed to send external routing information for redistribution. They use type 7 LSAs to tell the ABRs about these external routes, which the Area Border Router then translates to type 5 external LSAs and floods as normal to the rest of the OSPF network.
