MPLS Manager creates a VLAN instance for each discovered Ethernet-VLAN VPWS that is implemented on Cisco devices, and for each discovered VPLS. For each discovered Cisco-based Ethernet-VLAN VPWS, MPLS Manager uses the VLAN ID to map the associated customer VLAN to the VPWS. For each discovered VPLS, MPLS Manager uses the VLAN ID and VLAN MPLS-side interfaces to map the associated customer VLAN to the VPLS.
