STIGQter: STIG Summary: Router Security Requirements Guide Version: 4 Release: 2 Benchmark Date: 23 Apr 2021:

The PE router providing MPLS Virtual Private Wire Service (VPWS) must be configured to have the appropriate virtual circuit identification (VC ID) for each attachment circuit.

Fix Recommendation

Assign globally unique VC IDs for each virtual circuit and configure the attachment circuits with the appropriate VC ID.

Configure the same VC ID on both ends of the VC.

Check Contents

Review the ingress and egress PE router configuration for each virtual circuit that has been provisioned.

Verify that the correct and unique VCID has been configured for the appropriate attachment circuit.

If the correct VC ID has not been configured on both routers, this is a finding.

Note: Ethernet over MPLS in VLAN mode transports Ethernet traffic from a source 802.1Q VLAN to a destination 802.1Q VLAN over a core MPLS network. The VC ID must be unique and the same on each end as it is used to connect the endpoints of the VC.
