Layer 2 Services over MPLS Implementation
When layer 2 services are configured over MPLS, layer 2 traffic is encapsulated in
MPLS frames and sent over MPLS tunnels. A virtual circuit (VC) label that indicates
a specific layer 2 connection, such as a Frame Relay data-link connection identifier
(DLCI), is pushed into the label stack between the tunnel label and the layer 2 data.
