| 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. |
| ℹ️ Check |
|---|
| This requirement is not applicable for the DODIN Backbone. Verify the OOBM interface is an adjacency in the IGP routing domain for the management network. Verify the IGP instance used for the management network is configured in a separate VRF from that used for the managed networks. ! router ospf 1 vrf OOBM router-id 77.0.0.10 ... ! router ospf 2 vrf PROD router-id 88.0.0.88 ... ! If the router does not enforce that IGP instances configured on the OOBM gateway router peer only with their own routing domain, this is a finding. |
| ✔️ Fix |
|---|
| Configure the router to enforce that IGP instances configured on the OOBM gateway router peer only with their own routing domain.
