Configuring Multicast Routing and Forwarding
Configuration Prerequisites
Before configuring multicast routing and forwarding, complete the following tasks:
z
Configure a unicast routing protocol so that all devices in the domain are interoperable at the
network layer.
z
Enable PIM (PIM-DM or PIM-SM).
Before configuring multicast routing and forwarding, prepare the following data:
z
The maximum number of downstream nodes for a single multicast forwarding table entry
z
The maximum number of entries in the multicast forwarding table
Configuring Multicast Static Routes
By configuring a multicast static route for a given multicast source, you can specify an RPF interface or
an RPF neighbor for multicast traffic from that source.

No multicast static route
configured by default.
When configuring a multicast static route, you cannot specify an RPF neighbor by its interface type and
number (
interface-type interface-number
) if the interface type of the RPF neighbor is Ethernet, Layer 3
aggregate, Loopback, RPR, or VLAN-interface; instead, you can such an RPF neighbor only by its
address (
rpf-nbr-address
).
