Enabling IP Protocol-Independent Multicast (PIM) on Layer 3 Interfaces

You must enable 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. interface vlan vlan-id

2. ip pim {dense-mode | sparse-mode | sparse-dense-mode}

DETAILED STEPS

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)#

Verifying IP Multicast Layer 3 Switching Summary

Note The show interface statistics command does not verify hardware-switched packets. It only verifies

packets switched by software.

The show ip pim interface count command verifies the IP multicast Layer 3 switching enable state on

IP PIM interfaces and the number of packets received and sent on the interface.

Use the following show commands to verify IP multicast Layer 3 switching information for an IP PIM

Layer 3 interface.

Step 1 Router#show ip pim interface count

State:* - Fast Switched, D - Distributed Fast Switched

Command Purpose

Step 1

interface vlan vlan-id

Example:

Router(config)#interface vlan 1

Selects the interface to be configured.

Step 2

ip pim {dense-mode | sparse-mode |

sparse-dense-mode}

Example:

Router(config-if)#ip pim dense-mode

Enables IP PIM on a Layer 3 interface.
