The router must enforce IGP instances configured on the Out Of Band Management (OOBM) gateway router only peer with their own routing domain.

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.

Check Text ( C-SRG-NET-000019-RTR-000012_chk )
Verify that the OOBM interface is an adjacency in the IGP routing domain for the management network. If the OOBM interface is an adjacency for routing domains that are not for the management network, this is a finding.

Fix Text (F-SRG-NET-000019-RTR-000012_fix)
Configure multiple IGP instances on the OOBM gateway router to peer only with their own routing domain.
