Summary

This chapter discussed three main topics: basic multicast, managing multicast source and receivers across VRFs, and transport architectures.

A virtualized enterprise network is fully capable of carrying multicast traffic. The simplest case has source and recipients in the same VRF, in which case the design decision is whether to use p2p transport or mVPN.

The mVPN extranet solution addresses the case where source and receiver are not in the same VRF.

Standards work continues in this area. The references sections in Appendices C and D include texts for the interested reader to follow new developments.
