Example for Configuring Basic PIM-SM
- Tracy Yang
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.
- Create the L3 VLAN interfaces.
- Enable IGMP on the L3 VLAN interfaces.
- 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 Query Timer Uptime vlan2 up 10.10.60.10 2 local 00:00:40 02:13:12 vlan3 up 10.10.61.10 2 other --:--:-- 00:36:29
• 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 vlan2 up 10.10.60.10 0 local 0 1 vlan3 up 10.10.61.10 1 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
--------- ------- ------ ------------------
vlan2 2 UP 10.10.60.10/24
fe80::4a6e:73ff:202:49a/64
vlan3 3 UP 10.10.61.10/24
fe80::e207:1b20:8c9:209b/64
• Run the run show igmp group command to show information about multicast group member ports.
admin@XorPlus# run show igmp groups Interface Address Group Mode Timer Srcs V Uptime vlan2 10.10.60.10 224.0.0.2 INCL --:--:-- 1 2 01:33:28 vlan2 10.10.60.10 224.0.0.13 INCL --:--:-- 1 2 01:33:28 vlan2 10.10.60.10 224.0.0.22 INCL --:--:-- 1 2 01:33:25 vlan3 10.10.61.10 224.0.0.2 INCL --:--:-- 1 2 00:33:12 vlan3 10.10.61.10 224.0.0.13 INCL --:--:-- 1 2 00:33:12 vlan3 10.10.61.10 224.0.0.22 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.
