The Dell OS10 out-of-band management (OOBM) gateway router must be configured to not redistribute routes between the management network routing domain and the managed network routing domain.

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; 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 (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.

ℹ️ Check
This requirement is not applicable for the DODIN Backbone. 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. Examine the configuration to verify that routes configured to be redistributed into the management network do not originate in a managed network, and vice versa. ! router ospf 10 vrf OOBM redistribute bgp 4 route-map dell4 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
This requirement is not applicable for the DODIN Backbone. 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. Delete any inappropriate route redistribution commands using the "no redistribute" command. OS10(config)# router ospf 10 vrf OOBM OS10(config-router-ospf-10)# no redistribute bgp 4 route-map dell4
