Configuring IP Multicast Routing
Configuring IP Multicast Routing
EXAMPLE
This example enables IP multicast distributed switching and specifies the PIM mode:
Switch# configure terminal
Switch(config)# ip multicast-routing distributed
Switch(config)# interface Gigabitethernet 1/0/0
Switch(config-if)# ip pim sparse-dense-mode
Switch(config-if)# end
Configuring PIM Stub Routing
The PIM Stub routing feature supports multicast routing between the distribution layer and the access layer. It supports
two types of PIM interfaces, uplink PIM interfaces, and PIM passive interfaces. A routed interface configured with the PIM
passive mode does not pass or forward PIM control traffic, it only passes and forwards IGMP traffic.
This procedure is optional.
BEFORE YOU BEGIN
 You must have IP multicast routing configured on both the stub router and the central router.
 You must have PIM mode (dense-mode, sparse-mode, or dense-sparse-mode) configured on the uplink interface
of the stub router.
 You must configure EIGRP stub routing to assist the PIM stub router behavior.
DETAILED STEPS
To disable PIM stub routing on an interface, use the no ip pim passive interface configuration command.
EXAMPLE
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 86 on page 679:
Switch(config)# ip multicast-routing distributed
Switch(config)# interface GigabitEthernet0/25
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
Command Purpose
1. configure terminal Enter global configuration mode.
2. interface interface-id Specify the interface on which you want to enable PIM stub
routing, and enter interface configuration mode.
3. ip pim passive Configure the PIM stub feature on the interface.
4. end Return to privileged EXEC mode.
5. show ip pim interface Display the PIM stub that is enabled on each interface.
6. show running-config Verify your entries.
7. copy running-config
startup-config
(Optional) Save your entries in the configuration file.
