Table 113. Advanced OSPFv3 Stub Area Configuration
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 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

has been 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.
