Enabling IP Multicast Routing Globally
You must enable IP multicast routing globally before you can enable IP multicast Layer 3 switching on
Layer 3 interfaces.
For complete information and procedures, refer to these publications:
•
•
To enable IP multicast routing globally, perform this task:
Command
Router(config)# ip multicast-routing
Router(config)# no ip multicast-routing
This example shows how to enable multicast routing globally:
Router(config)# ip multicast-routing
Router(config)#
Enabling IP PIM on Layer 3 Interfaces
You must enable PIM on the Layer 3 interfaces before IP multicast Layer 3 switching functions on those
interfaces.
To enable IP PIM on a Layer 3 interface, perform this task:
Command
Step 1
Router(config)# interface {{vlan vlan_ID} |
1
{type
slot/port}}
Step 2
Router(config-if)# ip pim {dense-mode |
sparse-mode | sparse-dense-mode}
Router(config-if)# no ip pim [dense-mode |
sparse-mode | sparse-dense-mode]
1.
type = ethernet, fastethernet, gigabitethernet, or tengigabitethernet
This example shows how to enable PIM on an interface using the default mode (sparse-dense-mode):
Router(config-if)# ip pim
Router(config-if)#
