Import External LSAs - Import and propagate external LSAs
Import No LSAs - Do not import and propagate external LSAs
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. This value is in hexadecimal.
NSSA Specific Parameters
Translator State - Translator State 'Enabled' means that the NSSA router OSPFv3 Area NssA
Translator Role has been set to always. Translator State of 'Elected' means a candidate NSSA
Border router is translating type-7 LSAs into type-5.' Disabled' implies tha a candidate NSSA Border
router is NOT translating type-7 LSAs into type-5.
