Quick Steps for Configuring PIM-DM

Note. PIM requires that IP Multicast Switching (IPMS) is enabled. IPMS is automatically enabled when

a multicast routing protocol (either PIM or DVMRP) is enabled globally and on an interface and when the

operational status of the interface is up. However, if you wish to manually enable IPMS on the switch, use

the ip multicast status command.

1Manually load PIM into memory by entering the following command:

-> ip load pim

2Create a router port (i.e., interface) on an existing VLAN by specifying a valid IP address. To do this,

use the ip interface command. For example:

-> ip interface vlan-2 address 178.14.1.43 vlan 2

Note. The ip interface command is not supported in Release 5.3.1. For this release, use the vlan router ip

command instead. See the OmniSwitch CLI Reference Guide for more information.

3Enable PIM on the interface using the ip pim interface command. For example:

-> ip pim interface vlan-2

Note. The interface on which the PIM is enabled must be an already configured IP interface on the switch.

4Map the PIM-Dense Mode (DM) protocol for a multicast group via the ip pim dense group command.

For example:

-> ip pim dense group 224.0.0.0/4

5Globally enable the PIM protocol by entering the following command. By default, PIM protocol status

is disabled.

-> ip pim sparse status enable

-> ip pim dense status enable
