Chapter 7. Large-Scale IP Multicast Routing

• Multicast Scoping ” This section examines the reasons for limiting the scope of IP multicast traffic, and the implementation of the two methods for multicast scoping: TTL scoping and administrative scoping.

• Case Study: Multicasting Across Non-Multicast Domains ” This case study introduces techniques for passing IP multicast traffic across routers that do not support IP multicast.

• Connecting to DVMRP Networks ” This section demonstrates strategies for connecting Cisco routers to DVMRP networks, and what parts of DVMRP are and are not supported by Cisco IOS Software.

• Inter-AS Multicasting ” This section introduces the issues and problems specific to routing IP multicast traffic between autonomous systems and discusses the operation of MBGP and MSDP as solutions to some of the problems.

• Case Study: Configuring MBGP ” This case study demonstrates the configuration of Multiprotocol BGP.

• Case Study: Configuring MSDP ” This case study demonstrates the configuration of MSDP.

• Case Study: MSDP Mesh Groups ” This case study demonstrates the configuration of MSDP mesh groups.

• Case Study: Anycast RP ” This case study demonstrates the configuration of Anycast RP.

• Case Study: MSDP Default Peers ” This case study demonstrates the configuration of MSDP default peers.

The preceding two chapters explained the present state of IP multicast routing protocols and the basics of configuring Cisco IOS Software for multicast routing. As with unicast protocols, however, you must take additional measures as your multicast domain grows to maintain stability, scalability, and controllability. This chapter examines some of the techniques and protocols available to you to accomplish those objectives.
