You can configure separate ranges of addresses in the PIM or PIM6 domain using the multicast distribution modes described in Table 1-22.
Table 1-22 PIM and PIM6 Multicast Distribution Modes
Tables 1-23 through 1-25 describe the most-used multicast configuration commands. For the full list of commands, refer to the Nexus Multicast Routing Configuration Guide in the reference section at the end of this chapter.
Table 1-23 Multicast Global-Level Commands
Table 1-24 Multicast Interface-Level Commands
Table 1-25 Multicast Global-Level BGP Verification Commands
Figure 1-18 shows the network topology for the configuration that follows, which demonstrates how to configure Nexus multicast routing.
