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

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 IGP routing instances is critical on the router to segregate traffic from each network.

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:

R3(config)#router ospf 1 vrf MGMT
R3(config-router)#network 0.0.0.0 0.0.0.0 area 0
R3(config-router)#exit
R3(config)#router ospf 2 vrf PROD
R3(config-router)#network 0.0.0.0 0.0.0.0 area 0
R3(config-router)#end
