CHAPTER 5. Internet Multicast and Multicast VPNs Based on MDLP In-Band Signa... - Pg. 323

CHAPTER Internet Multicast and Multicast VPNs Based on MDLP In-Band Signaling 5.1 INTRODUCTION 5 Chapter 4 introduced the building blocks of Label Switched Multicast, also referred to as Next- Generation Multicast, which is the enabler for Next-Generation Multicast VPNs. It provided a deep dive into the control plane infrastructure, which is built using BGP and also the various options for enabling the data plane, such as RSVP-TE, MLDP, and PIM-SM. Each of these is standards based and interoperable across vendors. In this chapter, we take a look at an implementation purely based on MLDP both from a control plane and data plane perspective (an MVPN application uses PIM for VPN specific multicast infor- mation; however, and this is the only exception). This implementation is based on the IETF draft
