Table 112. Advanced OSPFv3 Common Area Configuration
New LSAs Originated In any given OSPFv3 area, a router will originate several LSAs. Each router
originates a router-LSA. If the router is also the Designated Router for any of
the area's networks, it will originate network-LSAs for those networks. This
value represents the number of LSAs originated by this router.
LSAs Received The number of LSAs received that were determined to be new instantiations.
This number does not include newer instantiations of self-originated LSAs.
Field Description
External Routing A definition of the router's capabilities for the area, including whether or not
AS-external-LSAs are flooded into or throughout the area.
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
database, excluding
AS External LSAs.
