Chapter 2. IMR Overview
Several protocols are required to enable IP multicast over multiple domains. These protocols, as well as their documentation, have been developed independently, and each has its own set of specific terms. The multiplicity of protocol development makes it challenging to create a workable, integrated multicast implementation.
The point of this chapter is to resolve the difficulty of implementation using these several protocols and to provide a working-level illustration of an interdomain multicast routing (IMR) system, end-to-end across multiple domains.
Figure 2-1 shows a simple network and serves as a reference for subsequent discussion in this chapter. The figure shows two interconnected autonomous systems (ASs) with fully ...
