13.6. CONCLUSION
Entire books are dedicated to the subject of managing the MPLS infrastructure and the services running over it; attempting to cover this subject in one chapter cannot do it justice. In fact, the topic is much broader than just the functionality defined in the standards bodies. An entire industry is built around tools that can aid in tasks such as performance monitoring for a service or an LSP, VPN provisioning, network visualization, offline path computation, event correlation or capacity planning.
Rather than attempting to provide a view of all management functions and tools, this chapter focused on router functionality developed specifically for troubleshooting and managing in an MPLS environment, such as LSPing, VCCV, ICMP tunneling and membership verification for VPNs. Although these topics constitute only a small part of the MPLS management story, they shed light on some of the unique issues that arise in MPLS environments.
