Title

The enclave must be dual homed to two geographically diverse DISN SDNs and DISN WAN Service (NIPRNet or SIPRNet) Aggregation Routers (AR) or DISN Provider Edge (PE) routers.

Description

<VulnDiscussion>Redundancy and dual homing is used within the DISN core to provide for continuity of operations (COOP) if a piece of equipment, circuit path, or an entire service delivery node is lost. DOD policy also requires DOD enclaves that support command and control (C2) users for data services to be dual homed to the DISN core SDNs. This means there will be two physically separate access circuits from the enclave to two geographically diverse DISN SDNs. Once the access circuits arrive a...

Fix Text (Documentation Requirement)

If the VVoIP system connects to the DISN WAN for VVoIP transport between enclaves AND the system is intended to provide assured service communications to any level of C2 user (Special C2, C2, C2(R)), ensure the enclave is dual homed to two geographically diverse DISN SDNs and DISN WAN Service (NIPRNet or SIPRNet) routers. NOTES: - This means there are two DISN (or commercial) access circuits (many circuits will have a commercial component, typically the "last mile") from the site/enclave to the DISN SDNs. - This assumes the site/enclave is NOT collocated with a DISN SDN such that a direct Ethernet or optical connection can be made. - If a site is located at a DISN SDN and is able to directly connect to the SDN using Ethernet or optical connections, the site may be able to rely on the dual...
