Framework for IP Multicast in MPLS

摘要

This document offers a framework for IP multicast deployment in anMPLS environment. Issues arising when MPLS techniques are applied toIP multicast are overviewed. The pros and cons of existing IPmulticast routing protocols in the context of MPLS are described andthe relation to the different trigger methods and label distributionmodes are discussed. The consequences of various layer 2 (L2)technologies are listed. Both point-to-point and multi-accessnetworks are considered.
