Table 143. Advanced OSPFv3 Stub 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 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.
Type of Service This field is the normal ToS associated with the stub metric.
