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, use the following commands beginning in global configuration mode: Step 1 Step 2 Command Router(config)# interface vlan vlan-id slot/port Router(config-if)# ip pim {dense-mode | sparse-mode | sparse-dense-mode} Purpose Selects the interface to be configured. Enables IP PIM on a Layer 3 interface. The following example shows how to enable PIM on an interface using the default mode (sparse-dense-mode): Router(config-if)# ip pim Router(config-if)# The following example shows how to enable PIM sparse mode on an interface: Router(config-if)# ip pim sparse-mode Router(config-if)# Cisco IOS Release 12.2(2)XT, 12.2(8)T, and 12.2(15)ZJ 99

To enable IP multicast routing globally, Use the following command in global configuration mode:
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, use the following commands beginning in global configuration
mode:
The following example shows how to enable PIM on an interface using the default mode
(
sparse-dense-mode
):
Router(config-if)#
ip pim
Router(config-if)#
The following example shows how to enable PIM sparse mode on an interface:
Router(config-if)#
ip pim sparse-mode
Router(config-if)#
Command
Purpose
Router(config)#
ip multicast-routing
Enables IP multicast routing globally.
