CISC-RT-000420 - The Cisco out-of-band management (OOBM) gateway router must be configured to have separate IGP instances for the managed network and management network.

Warning! Audit Deprecated

This audit has been deprecated and will be removed in a future update.

Information

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.

NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.

Solution

This requirement is not applicable for the DODIN Backbone.

Configure the router to have a separate IGP instance for the management network as shown in the example below.

RP/0/0/CPU0:R2(config)#router ospf 2 vrf MGMT
RP/0/0/CPU0:R2(config-ospf-vrf)#area 0
RP/0/0/CPU0:R2(config-ospf-vrf-ar)#interface GigabitEthernet0/0/0/0.2
RP/0/0/CPU0:R2(config-ospf-vrf-ar-if)#exit
RP/0/0/CPU0:R2(config-ospf-vrf-ar)#exit
RP/0/0/CPU0:R2(config-ospf-vrf)#exit
RP/0/0/CPU0:R2(config-ospf)#exit
RP/0/0/CPU0:R2(config)#router ospf 3 vrf PROD
RP/0/0/CPU0:R2(config-ospf-vrf)#area 0
RP/0/0/CPU0:R2(config-ospf-vrf-ar)#interface GigabitEthernet0/0/0/0.3
RP/0/0/CPU0:R2(config-ospf-vrf-ar-if)#end
