This object reports the count of link-local LSAs held in the link-local database associated with an OSPF virtual link, a logical adjacency tunneled through a transit area to connect an otherwise-disconnected area to the backbone, mirroring cospfIfLsaCount but for virtual rather than physical interfaces. It matters in the specific troubleshooting context of virtual-link-based area connectivity, where the transit-area path itself can introduce its own link-local LSA consistency concerns separate from the two endpoint areas. An admin diagnosing an OSPF virtual link that is up but behaving oddly would check this alongside the equivalent physical-interface counters on the two endpoint routers.
