IP multicast does not support secondary IP addresses. Namely, multicast can be routed and forwarded
only through primary IP addresses even if secondary IP addresses are configured on the ports. For more
information about primary and secondary IP addresses, see "Configuring IPv4 address."

Configuring multicast routing and forwarding
This section describes how to configure multicast routing and forwarding.
Configuration prerequisites
Before you configure multicast routing and forwarding, complete the following tasks:
• Configure a unicast routing protocol so that all devices in the domain are interoperable at the
network layer.
• Enable PIM (PIM-DM or PIM-SM).
• Determine the maximum number of downstream nodes for a single multicast forwarding table entry.
• Determine the maximum number of entries in the multicast forwarding table.
Configuring static multicast routes
By configuring a static multicast route for a given multicast source, you can specify an RPF interface or an
RPF neighbor for multicast traffic from that source. If you want to remove a specific static multicast route,
