This alternative concerns svi addressing and inter-vlan routing; its associated risk is: Duplicate gateways or mismatched prefix lengths can make hosts reachable only locally or create asymmetric routing. The observed case A route is installed in the management VRF while client traffic is evaluated in the default VRF requires the more specific static route preference and default path control. The targeted action is: Define next hops and route preferences using the intended VRF and reachable paths, then check both forward and reverse reachability.

This alternative concerns ospf area and neighbor formation; its associated risk is: An OSPF neighbor mismatch can leave a physical link working while required prefixes never populate the routing table. The observed case A route is installed in the management VRF while client traffic is evaluated in the default VRF requires the more specific static route preference and default path control. The targeted action is: Define next hops and route preferences using the intended VRF and reachable paths, then check both forward and reverse reachability.
