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 C-BSR and C-RP on Switch B to utilize PIM BootStrap Router mechanism to accomplish dynamic RP election.
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
admin@XorPlus# set protocols pim interface vlan-3

Step5 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

Step6 Commit the configurations.

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 Mode V PIMstate Priority DRaddr Neighbors
---------- -------- ------ - -------- -------- --------------- ---------
vlan-2 UP Sparse 2 DR 1 10.10.1.1 0
vlan-3 UP Sparse 2 DR 1 10.10.3.1 0
register_vif UP Sparse 2 DR 1 10.10.1.1 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

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
admin@XorPlus# set protocols pim interface vlan-3

Step4 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
admin@XorPlus# set protocols pim interface vlan-3

Step4 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

Step5 Commit the configuration.

admin@Xorplus# commit

Step6 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 Mode V PIMstate Priority DRaddr Neighbors
---------- -------- ------ - -------- -------- --------------- ---------
vlan-2 UP Sparse 2 DR 1 10.10.2.1 0
vlan-3 UP Sparse 2 DR 1 10.10.4.1 0
register_vif UP Sparse 2 DR 1 10.10.2.1 0
