The key attributes for OSPFVirtualLink are the same as those for OSPFNeighborEndpoint, except that the attribute names contain 1 or 2 to denote the attribute set for each of the two endpoints involved in the virtual link. The Endpoint1DisplayName and Endpoint2DisplayName attributes identify the OSPF endpoints for the attribute sets. “Attributes for OSPFNeighborEndpoint” on page 54 provides a list of the key attributes for OSPFNeighborEndpoint.

Network Protocol Manager for OSPF uses the two sets of OSPFVirtualLink attributes as well as other attributes to diagnose OSPF virtual link problems and to detect OSPF virtual link events.
