A preproduction adjacency test reaches the intended OSPF state with the expected routes. Such an observation would verify a separate issue: A routing plan lists OSPF but omits area IDs, interface addresses and neighbor prerequisites. It would follow the distinct action: Define OSPF participating interfaces, areas, authentication policy and neighbor reachability in the implementation plan. Here the reported failure is A multicast application spans several routed VLANs but the design documents only a single VLAN IGMP setting. The decisive result for Northpoint Health must instead be: A test stream reaches intended subscribers on both sides of the routed boundary without flooding unrelated VLANs.

A link-failure test retains the required campus reachability without creating Layer 2 loops. Such an observation would verify a separate issue: The network has two data rooms and the plan provides only one unprotected uplink from each access layer. It would follow the distinct action: Specify redundant uplinks and an appropriate loop-safe high-availability topology for each failure domain.
