Description
The ISSM will ensure Releasable Local Area Network (REL LAN) environments are documented in the SSAA.
ℹ️ Check
Interview the ISSM and review the SSAA. GRE tunnels found on a premise or edge SIPRNet router that have an endpoint within the REL IP address space must be documented in the SSAA. If the REL LAN has not been documented in the SSAA, this is a finding.
✔️ Fix
The ISSM will document GRE tunnels defined on a premise or edge SIPRNet router that have an endpoint within the REL IP address space.
