Configuring Multicast (PIM and PIM6)

Protocol Independent Multicast (PIM), which is used between multicast-capable routers, advertises group membership across a routing domain by constructing multicast distribution trees. PIM builds shared distribution trees on which packets from multiple sources are forwarded, as well as source distribution trees on which packets from a single source are forwarded.

Cisco NX-OS supports PIM sparse mode for IPv4 networks (PIM) and for IPv6 networks (PIM6). In PIM sparse mode, multicast traffic is sent only to locations of the network that specifically request it. You can configure PIM and PIM6 to run simultaneously on a router. You can use PIM and PIM6 global parameters to configure rendezvous points (RPs), message packet filtering, and statistics. You can use PIM and PIM6 interface parameters to enable multicast, identify PIM borders, set the PIM hello message interval, and set the designated router (DR) priority.

For more information about PIM and PIM6, see the Cisco Nexus 9000 Series NX-OS Multicast Routing Configuration Guide.

This section contains payload examples and CLIs to demonstrate how to use the NX-API REST API to configure PIM on Cisco Nexus 3000 and 9000 Series switches and to show how the REST APIs correspond to the CLI commands.
