Book Title
Enabling IP Protocol-Independent Multicast (PIM) on Layer 3 Interfaces
You must enable protocol-independent multicast (PIM) on the Layer 3 interfaces before enabling IP
multicast Layer 3 switching functions on those interfaces.
Beginning in global configuration mode, follow these steps to enable IP PIM on a Layer 3 interface.
SUMMARY STEPS
1. enable
2. configure terminal
3. interface vlan vlan-id
4. ip pim {dense-mode | sparse-mode | sparse-dense-mode}
DETAILED STEPS
Examples
The following example shows how to enable PIM on an interface using the default mode
(sparse-dense-mode):
Router(config-if)# ip pim sparse-dense mode
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
Step 1
enable
Example:
Router> enable
Enables privileged EXEC mode.
• Enter your password if prompted.
Step 2
configure terminal
Example:
Router# configure terminal
Enters global configuration mode.
Step 3
interface vlan vlan-id
Router(config)# interface vlan 1
Selects the interface to be configured.
Step 4
ip pim {dense-mode | sparse-mode |
sparse-dense-mode}
Example:
Router(config-if)# ip pim sparse-dense mode
Enables IP PIM on a Layer 3 interface.
