Chapter 4. MPLS Traffic Engineering

As of this writing, Virtual Private LAN Services (VPLS) and Ethernet over Multiprotocol Label Switching (EoMPLS) technologies are the most appropriate methods for extending a Layer 2 VLAN. In most cases, these technologies require enabling MPLS in the core network. In addition, correlated MPLS features such as traffic engineering (TE) and Fast Reroute (FRR) should be considered for improving network transport.

Understanding MPLS-TE

When IP or Label Distribution Protocol (LDP) is the transport mechanism, traffic always follows the Interior Gateway Protocol (IGP) shortest path and benefits from equal-cost multipath (ECMP) balancing.

MPLS Traffic Engineering (MPLS-TE) is based on a different approach. It relies ...
