M6100 Web Management User Guide Table 100. OSPF Common Area Configuration Field External Routing SPF Runs Area Border Router Count Area LSA Count Area LSA Checksum Flood List Length Import Summary LSAs Description A definition of the router's capabilities for the area, including whether or not AS-external-LSAs are flooded into/throughout the area. If the area is a stub area, then these are the possible options for which you may configure the external routing capability, otherwise the only option is Import External LSAs. • Import External LSAs - Import and propagate external LSAs. • Import No LSAs - Do not import and propagate external LSAs. 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 is the number of LSAs on this area's flood list. The summary LSAs will be enabled/disabled imported into this area.
