The Cisco ISR 4000 Series router must enforce that Interior Gateway Protocol instances configured on the out-of-band management gateway router only peer with their own routing domain.

Target Key

If the gateway router is not a dedicated device for the out-of-band management 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.

Fix Text

Ensure that multiple IGP instances configured on the OOBM gateway router peer only with their appropriate routing domain. Verify that the all interfaces are configured for the appropriate IGP instance.

Check Content

Verify that the OOBM interface is an adjacency only in the IGP routing domain for the management network. The following would be an example where EIGRP is run on the management network and OSPF in the managed network The network is the OOBM backbone and is the local management LAN connecting to the OOBM interfaces of the managed network (i.e., the private and service network) elements. interface Serial0/0 description to_OOBM_Backbone ip address ! interface FastEthernet 0/0 description Enclave_Management_LAN ip address ! interface FastEthernet 0/1 description to_our_PrivateNet ip address ! interface FastEthernet 0/2 description to_our_ServiceNet ip address ! router ospf 1 network ! router eigrp 12 network If the OOBM interface is not an adjacency only in the IGP routing domain for the management network, this is a finding.
