The router must enforce that any interface used for OOBM traffic is configured to be passive for the IGP that is utilized on that interface.

Description
The OOBM access switch will connect to the management interface of the managed network elements. The management interface can be a true OOBM interface or a standard interface functioning as the management interface. In either case, the management interface of the managed network element will directly connect to the OOBM network. An OOBM interface does not forward transit traffic, thereby, providing complete separation of production and management traffic. Since all management traffic is immediately forwarded into the management network, it is not exposed to possible tampering. The separation also ensures that congestion or failures in the managed network do not affect the management of the device. If the device does not have an OOBM port, the interface functioning as the management interface must be configured so that management traffic, both data plane and control plane, does not leak into the managed network and that production traffic does not leak into the management network.

Check Text ( C-SRG-NET-000019-RTR-000014_chk )
Review the configuration to verify the management interface is configured as passive for the IGP instance for the managed network. If the management interface is not configured as passive for the IGP instance for the managed network, this is a finding.

Fix Text (F-SRG-NET-000019-RTR-000014_fix)
Configure the management interface as passive for the IGP instance configured for the managed network.
