Networking Requirements

As shown in Figure 1, Host B wants to receive multicast data from Host A (Source) through the Pica8 Switch.

Figure1. User Configuration Topology of PIM-SM

 

 

 

 

 

 

 

Follow the configuration roadmap below to complete the configuration on PICA8 Switch.

  1. Create the L3 VLAN interfaces.

  2. Enable IGMP on the L3 VLAN interfaces.

  3. Enable PIM-SM on L3 VLAN interfaces.

Procedure

Host A (Source)

•  Add route on Host A to reach Host B.

    For example, use the following command on Linux system,

    sudo route add default gw 10.10.60.10 eth1

•  Run iPerf on Host A. 

Host B (Receiver)

•  Add route on Host B to reach Host A.

    For example, use the following command on Linux system,

    sudo route add default gw 10.10.61.10 eth1

•  Run iPerf on Host B. 

PICA8 Switch

Step1         Create the L3 VLAN interfaces and assign VLAN to ports.            

admin@Xorplus# set vlans vlan-id 2 l3-interface vlan2 admin@Xorplus# set l3-interface vlan-interface vlan2 address 10.10.60.10 prefix-length 24 admin@Xorplus# set interface gigabit-ethernet ge-1/1/2 family ethernet-switching native-vlan-id 2 admin@Xorplus# set interface gigabit-ethernet ge-1/1/2 family ethernet-switching port-mode trunk admin@Xorplus# set interface gigabit-ethernet ge-1/1/2 family ethernet-switching vlan members 3 admin@Xorplus# set vlans vlan-id 3 l3-interface vlan3 admin@Xorplus# set l3-interface vlan-interface vlan3 address 10.10.61.10 prefix-length 24 admin@Xorplus# set interface gigabit-ethernet ge-1/1/3 family ethernet-switching native-vlan-id 3 admin@Xorplus# set interface gigabit-ethernet ge-1/1/3 family ethernet-switching port-mode trunk admin@Xorplus# set interface gigabit-ethernet ge-1/1/3 family ethernet-switching vlan members 2

Step2         Enable IP routing.

admin@Xorplus# set ip routing enable true

Step3         Enable IGMP on the L3 VLAN interfaces.

admin@Xorplus# set protocols igmp interface vlan2 admin@Xorplus# set protocols igmp interface vlan3

Step4         Enable PIM on the L3 VLAN interfaces and assign the group ID.

Step5         Configure the log level.

Step6         Commit the configurations.

Verify the Configuration


•     Run the run show igmp interface command to check the IGMP interface configuration.     

•  Run the run show pim interface command to check the PIM configuration and status.

• •  Run the run show l3-interface brief command to check the VLAN interface configuration.

•  Run the run show igmp group command to show information about multicast group member ports.

 

Verify End to End Connectivity between Host A and Host B

•  Connectivity between Host A and Host B.

•  IPerf result from Host A to Host B.

•  IPerf result from Host B to Host A.
