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 minimum TTL value required for a multicast packet to be forwarded.
• 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,
use the undo ip rpf-route-static command. If you want to remove all static multicast routes, use the delete
ip rpf-route-static command.
To configure a static multicast route:
