Field SPF Runs Area Border Router Count Area LSA Count Area LSA Checksum Type of Service Description 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. The total number of area border routers reachable within this area. This is initially zero, and is calculated in each SPF Pass. The total number of link-state advertisements in this area's link-state database, excluding AS External LSAs. 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 field is the normal TOS associated with the stub metric. Routing 238
