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.

Table 132. OSPF 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 This field displays if and how the NSSA border router translates Type 7 into
T
ype 5. Possible options are as follows:
• Enabled.
The NSSA border router’s translator role is 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.
