Network Manager Protocol view of its managed OSPF topology demonstrates how Network Protocol Manager for OSPF models (represents) its managed OSPF topology. The underlying physical-transport objects in the model, shown as white rectangles, are managed by IP Availability Manager. As such, Network Protocol Manager for OSPF receives the status of these objects from IP Availability Manager.
Not all of the underlying physical-transport objects that are understood by Network Protocol Manager for OSPF are shown in Figure 20. For example, Network Protocol Manager for OSPF also understands Cable and TrunkCable objects. In addition, the network cloud in Figure 20 represents various types of connections between the two physical interfaces that are underlying the OSPF neighbor relationship, including connections between ports on intermediate switches.
