Table 142. 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 Type 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.
