Table 31.
Field Description
SPF Runs The number of times that the intra-area route table
has been 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' LS checksums contained in this
area's link-state database. This sum excludes
external (LS type 5) link-state advertisements. The
sum can be used to determine if there has been 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:
• enabled: The NSSA border router's translator
role has been 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.
