Configuring multicast routing and forwarding
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,
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.
When you configure a static multicast route, you cannot specify an RPF neighbor by providing the type
and number (interface-type interface-number) of the interface if the interface of the RPF neighbor is a
Layer 3 Ethernet interface, Layer 3 aggregate interface, Loopback interface, or VLAN interface. Instead,
you can specify such an RPF neighbor only by its address (rpf-nbr-address).
To configure a static multicast route:

No static multicast route is
configured by default.
