Chapter 2. Basic MPLS Configuration

In the first chapter, you were introduced to the MPLS forwarding model in which labels are used to forward packets for a certain destination network. You were also provided details on frame- and cell-mode MPLS operation.

In this chapter, the following topics are covered:

• Frame-mode MPLS configuration and verification

  - Basic frame-mode MPLS configuration and verification

  - Frame-mode MPLS over RFC 2684 (obsoletes RFC 1483) routed PVC

• Cell-mode MPLS over ATM configuration and verification

  - Basic cell-mode MPLS configuration and verification

  - Configuring cell-mode MPLS with and without virtual circuit merge (VC-merge)

  - MPLS over VP tunnels configuration and verification

  - Configuring MPLS over ATM using BPX ATM switch and 7200 as label switch controller (LSC)
