Chapter 10. MPLS TE Deployment Tips

This chapter covers the following topics:

• Bandwidth and Delay Measurements

• Fine-Tuning MPLS TE Parameters

• Migrating IS-IS from Narrow to Wide Metrics

• TE and Multicast

• Tunnel Identification Schemes

• Combining MPLS TE with MPLS VPNs

• Deployment Possibilities

By now, you've probably read Chapter 9, "Network Design with MPLS TE." So hopefully you have a grip on some of the different ways MPLS TE can be deployed and how it scales. This chapter takes a look not at the theoretical side of things, but at some of the real-world aspects of MPLS TE deployment. This chapter covers several things that are useful to understand when considering MPLS TE deployment in the real world. Here are the specific things that are covered:

• Bandwidth and delay measurements

• Tuning timers and tweaking knobs

• Migrating IS-IS from narrow to wide metrics

• TE and multicast coexistence

• Tunnel identification schemes

• Combining MPLS TE and MPLS VPNs

• Deployment possibilities

Consider this chapter an assortment of tools for your MPLS TE toolbox. You might not use all of them (if you don't run multicast, or MPLS VPNs, or IS-IS), so feel free to read only the parts that are of interest to you.
