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.

admin@Xorplus# set protocols pim interface vlan2 sm admin@Xorplus# set protocols pim interface vlan3 sm admin@Xorplus# set protocols pim rp 10.10.60.10 group 226.0.0.0/8 admin@Xorplus# set protocols pim rp 10.10.61.10 group 226.0.0.0/8

Step5         Configure the log level.

admin@Xorplus# set protocols pim traceoption trace admin@Xorplus# set protocols igmp traceoption trace admin@Xorplus# set system log-level trace

Step6         Commit the configurations.

admin@Xorplus# commit

Verify the Configuration


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

admin@XorPlus# run show igmp interface Interface State Address V Querier QuerierIp Query Timer Uptime vlan2 up 10.10.60.10 3 local 10.10.60.10 00:00:14 00:04:28 vlan3 up 10.10.61.10 3 local 10.10.61.10 00:00:14 00:04:28

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

admin@Xorplus# run show pim interface Interface State Address PIM Nbrs PIM DR FHR IfChannels pimreg up 0.0.0.0 0 local 0 0 vlan2 up 10.10.60.10 0 local 0 0 vlan3 up 10.10.61.10 0 local 0 0

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

admin@XorPlus# run show l3-interface brief Interface Vlan ID Status Addr Description --------------- ------- ------ ------------------------------------------- ---------------------------------------- vlan2 2 UP 10.10.60.10/24 fe80::e81:3e20:15c:0/64 vlan3 3 UP 10.10.61.10/24 fe80::e81:3e20:25c:0/64

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

admin@XorPlus# run show igmp groups Interface Group Mode Timer Srcs V Uptime vlan2 224.0.0.2 INCL --:--:-- 1 2 01:33:28 vlan2 224.0.0.13 INCL --:--:-- 1 2 01:33:28 vlan2 224.0.0.22 INCL --:--:-- 1 2 01:33:25 vlan3 224.0.0.2 INCL --:--:-- 1 2 00:33:12 vlan3 224.0.0.13 INCL --:--:-- 1 2 00:33:12 vlan3 224.0.0.22 INCL --:--:-- 1 2 00:33:09

 

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.
