The management prefix is absent from unauthorized areas and desired production prefixes remain reachable. Such an observation would verify a separate issue: A multi-area OSPF design accidentally advertises a management subnet into the production area. It would follow the distinct action: Apply the intended interface participation and area advertisement policy rather than indiscriminate routing. Here the reported failure is A switch-to-router handoff requires a routed point-to-point connection, not a bridged access port. The decisive result for Dunhaven University must instead be: The two routed interfaces exchange IP packets across the point-to-point subnet.

A client reaches an authorized off-link IPv6 prefix through its correct default router. Such an observation would verify a separate issue: A new IPv6 VLAN has global addresses but no route beyond its link-local neighborhood. It would follow the distinct action: Configure IPv6 gateway routing and required neighbor-discovery/route advertisement behavior. Here the reported failure is A switch-to-router handoff requires a routed point-to-point connection, not a bridged access port. The decisive result for Dunhaven University must instead be: The two routed interfaces exchange IP packets across the point-to-point subnet.

OSPF neighbors reach Full where appropriate and relevant routes appear in routing tables. Such an observation would verify a separate issue: Two neighboring distribution switches see each other at IP level but OSPF never forms adjacency. It would follow the distinct action: Match required OSPF area and adjacency settings and confirm L3 interface state and neighbor discovery. Here the reported failure is A switch-to-router handoff requires a routed point-to-point connection, not a bridged access port.
