DETAILED STEPS
PurposeCommand or Action
Enables privileged EXEC mode.enable
Step 1
Example:
Device> enable
•
Enter your password if prompted.
Enters the global configuration mode.configure terminal
Example:
Device# configure terminal
Step 2
Enables IP multicast routing.ip multicast-routing
Step 3
Example:
Device(config)# ip
IP multicast routing is supported with Multicast Forwarding Information Base
(MFIB) and Multicast Routing Information Base (MRIB).
multicast-routing
Specifies the Layer 3 interface on which you want to enable multicast routing,
and enters interface configuration mode.
interface interface-id
Example:
Device(config)# interface
Step 4
The specified interface must be one of the following:
• A routed port—A physical port that has been configured as a Layer 3 port
by entering the no switchport interface configuration command. You

will also need to enable IP PIM sparse-dense-mode on the interface, and
join the interface as a statically connected member to an IGMP static
group. For a configuration example, see Example: Interface Configuration
as a Routed Port, on page 95
• An SVI—A VLAN interface created by using the interface vlan vlan-id
global configuration command. You will also need to enable IP PIM
sparse-dense-mode on the VLAN, join the VLAN as a statically connected
member to an IGMP static group, and then enable IGMP snooping on the
