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

Description
If the gateway router is not a dedicated device for the OOBM network, several safeguards must be implemented for containment of management and production traffic boundaries. Since the managed network and the management network are separate routing domains, separate IGP routing instances must be configured on the router, --one for the managed network and one for the OOBM network. In addition, the routes from the two domains must not be redistributed to each other.

Check Text ( C-SRG-NET-000019-RTR-000013_chk )
Verify the IGP instance used for the managed network does not redistribute routes into the IGP instance used for the management network, and vice versa. If the IGP instance used for the managed network redistributes routes into the IGP instance used for the management network, or vice versa, this is a finding.

Fix Text (F-SRG-NET-000019-RTR-000013_fix)
Configure the IGP instance used for the managed network to prohibit redistribution of routes into the IGP instance used for the management network, and vice versa.
