Ethernet circuit cross-connect (CCC) encapsulation on pseudowire subscriber logical interface

CCC encapsulation is supported on the transport side of an MPLS pseudowire subscriber logical interface. This feature helps in migrating or deploying seamless MPLS architectures in access networks. Customers deploying either business edge or broadband residential edge access networks use this feature to configure interfaces over the virtual Ethernet interface similar to what is already available on physical Ethernet interfaces. You can define only one transport logical interface per pseudowire subscriber logical interface. Although the unit number can be any valid value, we recommend that unit 0 represent the transport logical interface. Two types of pseudowire signaling are allowed, Layer 2 circuit and Layer 2 VPN.
