The Dell OS10 out-of-band management (OOBM) gateway router must be configured to have separate Interior Gateway Protocol (IGP) instances for the managed network and management network.

| Description | ||||
| If the gateway router is not a dedicated device for the OOBM network, implementation of several safeguards for containment of management and production traffic boundaries must occur. Since the managed and management network are separate routing domains, configuration of separate IGP routing instances is critical on the router to segregate traffic from each network. | ||||

If the router does not enforce that IGP instances configured on the OOBM gateway router peer only with their own routing domain, this is a finding.
Fix Text (F-73797r1052433_fix)
Configure the router to enforce that IGP instances configured on the OOBM gateway router peer only with their own routing domain.
