Chapter 1 Configuring IP Multicast Routing
Configuring IP Multicast Routing
Enabling PIM Stub Routing
Beginning in privileged EXEC mode, follow these steps to enable PIM stub routing on an interface. This
procedure is optional.
To disable PIM stub routing on an interface, use the no ip pim passive interface configuration command.
In this example, IP multicast routing is enabled, Switch A PIM uplink port 25 is configured as a routed
uplink port with
spare-dense-mode enabled. PIM stub routing is enabled on the VLAN 100 interfaces
and on Gigabit Ethernet port 20 in Figure 1-2 :
Switch(config)# ip multicast-routing distributed
Switch(config)# interface GigabitEthernet3/0/25
Switch(config-if)# no switchport
Switch(config-if)# ip address 3.1.1.2 255.255.255.0
Switch(config-if)# ip pim sparse-dense-mode
Switch(config-if)# exit
Switch(config)# interface vlan100
Switch(config-if)# ip pim passive
Switch(config-if)# exit
Switch(config)# interface GigabitEthernet3/0/20
Switch(config-if)# ip pim passive
Switch(config-if)# exit
Switch(config)# interface vlan100
Switch(config-if)# ip address 100.1.1.1 255.255.255.0
Switch(config-if)# ip pim passive
Switch(config-if)# exit
Switch(config)# interface GigabitEthernet3/0/20
Switch(config-if)# no switchport
Switch(config-if)# ip address 10.1.1.1 255.255.255.0
Switch(config-if)# ip pim passive
Switch(config-if)# end
To verify that PIM stub is enabled for each interface, use the show ip pim interface privileged EXEC
command:
Switch# show ip pim interface

Command Purpose
Step 1 configure terminal Enter global configuration mode.
Step 2
interface interface-id Specify the interface on which you want to enable PIM stub routing, and
enter interface configuration mode.
Step 3
ip pim passive Configure the PIM stub feature on the interface.
Step 4 end Return to privileged EXEC mode.
Step 5 show ip pim interface Display the PIM stub that is enabled on each interface.
Step 6
show running-config Verify your entries.
Step 7
copy running-config startup-config (Optional) Save your entries in the configuration file.
