b. Candidate. Cause the router to participate in the translator election process when it
attains border router status.
9. In the T
ranslator 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.
10. In the Redistribute Mode field, select to Enable or Disable.
This configures the NSSA ABR so that learned external routes are redistributed to the
NSSA.

Table 144. 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.
