ospfMultiProcessAreaLsaCksumSum — Edgecore MIB copies (Observium Community)
The 32-bit 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. The value should be treated as unsigned when comparing two sums of checksums.
