The Juniper out-of-band management (OOBM) gateway router must be configured to have separate 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 Interior Gateway Protocol routing instances is critical on the router to segregate traffic from each network.

ℹ️ Check
This requirement is not applicable for the DoDIN Backbone. Verify that the OOBM interface is an adjacency in the IGP domain for the management network via separate VRF as shown in the example below. } protocols { ospf { area 0.0.0.0 { interface ge-2/0/0; interface ge-2/1/0; } } } routing-instances { VRF_MGMT { instance-type vrf; interface ge-1/0/0; interface ge-1/1/0; route-distinguisher 10.1.12.0:12; vrf-target { import target:1234:4567; export target:1234:4567; } routing-options { router-id 11.11.11.11; } protocols { ospf { area 0.0.0.0 { interface ge-1/0/0; interface ge-1/1/0; } } } } } If the router is not configured to have separate IGP instances for the managed network and management network, this is a finding.
