JUNI-RT-000450 - The Juniper router providing connectivity to the NOC must be configured to forward all in-band management traffic via an IPsec tunnel - IPsec
Information
When the production network is managed in-band, the management network could be housed at a NOC that is located remotely at single or multiple interconnected sites. NOC interconnectivity, as well as connectivity between the NOC and the managed network, must be enabled using IPsec tunnels to provide the separation and integrity of the managed traffic.Solution
This requirement is not applicable for the DoDIN Backbone.Ensure that all traffic from the managed network to the management network is secured via IPsec tunnel as shown in the configuration examples below.
Configure an IPsec tunnel to be used to transport the management traffic.

Configure a filter that will select which traffic to be forwarded via the IPsec tunnel by specifying the security association bound to the tunnel.
