| Review the perimeter router configuration to verify filters are in place to restrict the IP addresses explicitly, or inexplicitly. Verify that ingress and egress filters for IPv6 have been defined to deny the 6bone address space and log all violations. If the ingress and egress filters do not deny the 6bone address space and log all violations, this is a finding. |
