6.13 Layer 2 over MPLS Configuration
Layer 2 over MPLS (also referred to as L2MPLS or Ethernet over MPLS) is a
solution for transporting Layer 2 packets over an MPLS network, allowing
service providers to use an MPLS network to provide connectivity between
customer sites over existing Layer 2 networks. Instead of using separate
networks for each customer, service providers can use a common MPLS
network to transport Layer 2 Ethernet traffic for different customers.
L2MPLS can provide customers with a virtual Ethernet link between remote
sites using the service provider's existing MPLS backbone. It also simplifies
service provider provisioning, since the edge switches on the service provider’s
network only need to support Layer 2 connectivity to the customer’s equipment.
L2MPLS encapsulates Ethernet frames in MPLS packets and uses label
stacking to forward them across an MPLS tunnel. Tunnel labels define the path
