Question

A service provider offers an EVPL service to a customer using an IOS XR PE router. The customer sends frames tagged with an outer VLAN 100 and inner VLAN 200 (QinQ). The PE must match these double-tagged frames on the access interface, remove the outer service-delimiting VLAN 100 before forwarding across the VPWS pseudowire, and re-impose VLAN 100 toward the customer on egress. Which Ethernet flow point (EFP) configuration on the ingress attachment circuit achieves this behavior?
