The router must enforce that the managed network domain and the management network domain are separate routing domains and the Interior Gateway Protocol instances are not redistributed or advertised to each other.

Description
If the gateway router is not a dedicated device for the out-of-band management network, several safeguards must be implemented for containment of management and production traffic boundaries, otherwise, it is possible that management traffic will not be separated from production traffic. Since the managed network and the management network are separate routing domains, separate Interior Gateway Protocol routing instances must be configured on the router, one for the managed network and one for the out-of-band management network. In addition, the routes from the two domains must not be redistributed to each other.

Check Text ( C-56313r1_chk )
Verify the Interior Gateway Protocol instance used for the managed network does not redistribute routes into the Interior Gateway Protocol instance used for the management network, and vice versa. If the Interior Gateway Protocol instance used for the managed network redistributes routes into the Interior Gateway Protocol instance used for the management network, or vice versa, this is a finding.
