Table 139.  Advanced OSPFv3 Common Area Configuration  
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 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. 
Import Summary LSAs  The summary LSAs are enabled or disabled imported into this area.
