This chapter covers the background and configuration of frame mode Multiprotocol Label Switching (MPLS). The following common configurations and features are discussed:
• 10-1: Configuring Basic MPLS—MPLS is a high-performance packet forwarding technology that is based on Layer 2 switching instead of relying only on Layer 3 routing. Routers use labels added between the Layer 2 and Layer 3 headers for forwarding decisions.
• 10-2: MPLS Traffic Engineering—Service providers can use traffic engineering on MPLS-enabled routers to route a customer’s network traffic based on throughput and delay. Tunnels are created for label switch paths (LSP) using the Resource Reservation Protocol (RSVP).
• 10-3: MPLS ...
