Summary
This chapter provided an overview of basic multicast operation, with a look at PIM Dense
Mode and PIM Sparse Mode. The foundation for interdomain multicast is provided by the
PIM-SM functionality. A protocol overview of MSDP and mBGP was also presented, with
emphasis on their interaction and dependencies. The chapter concluded with a case study
on deploying interdomain IP multicast in a service provider network.
This chapter focused on MSDP and mBGP from a deployment standpoint. A detailed
discussion of IP multicast and PIM protocol internals is outside the scope of this topic.
Further information on IP multicast deployment can be found in the Cisco Press
publication,
Developing IP Multicast Networks
, by Beau Williamson.
