Lecture 1 - IP Multicast Basics and Addressing

This is the first video of a complete lecture series on IP Multicast and its implementation on both IOS and Junos routers with a focus on CCIE and JNCIE candidate requirements.

In this video we discuss the following topics:

- What is IP multicast and its relevance to CCIE and JNCIE
- How does IP multicast differ from broadcast and replicated unicast
- Why is multicast more efficient than broadcast and replicated unicast
- The addressing of an IP multicast packet, the class of IP space used, the packet structure and the flat nature of the Class D space
- The need to generate unique ethernet MAC addresses to use as destination multicast MACs
- The addressing of a layer 2 ethernet packet encapsulating IP Multicast
- How multicast IPs are mapped to multicast ethernet MAC addresses and how up to 32 IP multicast IPs can potentially map to a single MAC address
