Example for Configuring PIM-SM
Networking Requirements
In the following topology, a multicast Source sends the multicast traffic to the Receiver through Switch C, Switch B and Switch A.
- Configure ge-1/1/2 as an IGMP interface on Switch A which is connected to the Receiver.
- In this example, the static route will be used to make the switches in PIM-SM domain can communicate with each other.

Procedure
Switch A
Step1 Configure VLAN.
admin@XorPlus# set vlans vlan-id 2 l3-interface vlan-2 admin@XorPlus# set vlans vlan-id 3 l3-interface vlan-3 admin@XorPlus# set interface gigabit-ethernet ge-1/1/1 family ethernet-switching native-vlan-id 2 admin@XorPlus# set interface gigabit-ethernet ge-1/1/2 family ethernet-switching native-vlan-id 3 admin@XorPlus# set l3-interface vlan-interface vlan-2 address 10.10.1.1 prefix-length 24 admin@XorPlus# set l3-interface vlan-interface vlan-3 address 10.10.3.1 prefix-length 24
Step2 Enable IP routing.
admin@Xorplus# set ip routing enable true
Step3 Enable IGMP on the L3 VLAN interfaces of the PIM router connected to the receiver.
admin@XorPlus# set protocols igmp interface vlan-3
Step4 Enable PIM-SM on the L3 VLAN interfaces.
admin@XorPlus# set protocols pim interface vlan-2 sm admin@XorPlus# set protocols pim interface vlan-3 sm
Step5 Configure the VLAN interface vlan-2 on Switch A as the static RP.
admin@XorPlus# set protocols pim rp 10.10.1.1 group 224.0.0.0/8
Step6 Configure static routes to other switches.
admin@XorPlus# set protocols static route 10.10.2.0/24 next-hop 10.10.1.2 admin@XorPlus# set protocols static route 10.10.4.0/24 next-hop 10.10.1.2
Step7 Commit the configurations.
admin@Xorplus# commit
Step8 Verify the configuration.
- Run run show pim interface command to show information about all interfaces on which PIM-SM is enabled.
admin@XorPlus# run show pim interface Interface State Address PIM Nbrs PIM DR FHR IfChannels vlan-2 up 10.10.1.1 1 local 0 1 vlan-3 up 10.10.3.1 2 local 0 0
- Run run show igmp interface command to show IGMP interface information.
admin@XorPlus# run show igmp interface Interface State Querier Timeout Version Groups ------------ -------- --------------- --------- --------- -------- vlan-2 DISABLED 10.10.1.1 None 2 0 vlan-3 UP 10.10.3.1 None 2 3 Interface State Address V Querier Query Timer Uptime vlan-2 up 10.10.1.1 3 local 00:00:40 02:13:12 vlan-3 mtrc 10.10.3.1 3 other --:--:-- 00:36:29
Switch B
Step1 Configure VLAN.
admin@XorPlus# set vlans vlan-id 2 l3-interface vlan-2 admin@XorPlus# set vlans vlan-id 3 l3-interface vlan-3 admin@XorPlus# set interface gigabit-ethernet ge-1/1/1 family ethernet-switching native-vlan-id 2 admin@XorPlus# set interface gigabit-ethernet ge-1/1/2 family ethernet-switching native-vlan-id 3 admin@XorPlus# set l3-interface vlan-interface vlan-2 address 10.10.1.2 prefix-length 24 admin@XorPlus# set l3-interface vlan-interface vlan-3 address 10.10.2.2 prefix-length 24 admin@XorPlus# set l3-interface loopback lo address 7.6.5.3 prefix-length 32
Step2 Enable IP routing.
admin@Xorplus# set ip routing enable true
Step3 Enable PIM-SM on the L3 VLAN interfaces.
admin@XorPlus# set protocols pim interface vlan-2 sm admin@XorPlus# set protocols pim interface vlan-3 sm
Step4 Configure the VLAN interface vlan-2 on Switch A as the static RP.
admin@XorPlus# set protocols pim rp 10.10.1.1 group 224.0.0.0/8
Step5 Commit the configuration.
admin@Xorplus# commit
Switch C
Step1 Configure VLAN.
admin@XorPlus# set vlans vlan-id 2 l3-interface vlan-2 admin@XorPlus# set vlans vlan-id 3 l3-interface vlan-3 admin@XorPlus# set interface gigabit-ethernet ge-1/1/1 family ethernet-switching native-vlan-id 2 admin@XorPlus# set interface gigabit-ethernet ge-1/1/2 family ethernet-switching native-vlan-id 3 admin@XorPlus# set l3-interface vlan-interface vlan-2 address 10.10.2.1 prefix-length 24 admin@XorPlus# set l3-interface vlan-interface vlan-3 address 10.10.4.1 prefix-length 24
Step2 Enable IP routing.
admin@Xorplus# set ip routing enable true
Step3 Enable PIM-SM on the L3 VLAN interfaces.
admin@XorPlus# set protocols pim interface vlan-2 sm admin@XorPlus# set protocols pim interface vlan-3 sm
Step4 Configure the VLAN interface vlan-2 on Switch A as the static RP.
admin@XorPlus# set protocols pim rp 10.10.1.1 group 224.0.0.0/8
Step5 Configure static routes to other switches.
admin@XorPlus#set protocols static route 10.10.1.0/24 next-hop 10.10.2.2 admin@XorPlus#set protocols static route 10.10.3.0/24 next-hop 10.10.2.2
Step6 Commit the configuration.
admin@Xorplus# commit
Step7 Verify the configuration.
- Run run show pim interface command to show information about all interfaces on which PIM-SM is enabled.
admin@XorPlus# run show pim interface Interface State Address PIM Nbrs PIM DR FHR IfChannels vlan-2 up 10.10.2.1 0 local 0 1 vlan-3 up 10.10.4.1 0 local 0 0
