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 admin-state command.
1 Manually load PIM into memory by entering the following command:
-> ip load pim
2 Create an IP router interface on an existing VLAN using the ip interface command. For example:
-> ip interface vlan-2 address 178.14.1.43 vlan 2
3 Enable PIM on the interface using the ip pim interface command. Note that the IP interface on which
PIM is enabled must already exist in the switch configuration. For example:
-> ip pim interface vlan-2
4 Map the PIM-Dense Mode (DM) protocol for a multicast group using the ip pim dense group
command. For example:
-> ip pim dense group 225.0.0.0/24
5 Globally enable the PIM protocol by entering the following command.
-> ip pim dense admin-state enable
6 Save your changes to the Working directory’s boot.cfg file by entering the following command:
-> write memory
Note. Optional. To verify PIM interface status, enter the show ip pim interface command. The display is
similar to the one shown here:
-> show ip pim interface

To verify global PIM status, enter the show ip pim sparse or show ip pim dense command. The display
for sparse mode is similar to the one shown here:
-> show ip pim sparse
