b. Candidate. Cause the router to participate in the translator election process when it
attains border router status.
10. In the Translator Stability Interval field, configure the translator of the NSSA.
The value is the period of time that an elected translator continues to perform its duties
after it determines that its translator status was deposed by another router.
The valid
range is 0 to 3600.
11. In the Redistribute Mode field, select to Enable or Disable.
This configures the NSSA ABR so that learned external routes are redistributed to the

The following table describes the nonconfigurable information that is displayed.
Table 141. Advanced OSPFv3 NSSA Area Configuration
Field Description
SPF Runs The number of times that the intra-area route table was calculated
using this area's link state database. This is typically done using
Dijkstra's algorithm.
Area Border Router Count The total number of area border routers reachable within this area.
This
is initially zero, and is calculated in each SPF pass.
Area LSA Count The total number of link state advertisements in this area's link state
database, excluding
AS external LSAs.
Area LSA Checksum The 32-bit unsigned sum of the link state advertisements' LSA
checksums contained in this area's link state database. This sum
excludes external (LSA type 5) link state advertisements.
The sum can
be used to determine if there was a change in a router's link state
database, and to compare the link state database of two routers.
Translator State The field tells you if and how the NSSA border router translates Type 7
into
T
ype 5. Possible values are as follows:
• Enabled.
The NSSA border router's translator role was set to
always.
• Elected.
The candidate NSSA border router is translating
Type 7
LSAs into Type 5.
• Disabled. The
candidate
NSSA border router is NOT translating
Type 7 LSAs into Type 5.
