Configuring MVR
Configuring MVR
Step1Â Â Â Â Â Â Â Â Â Configure VLANs for upstream port and access port respectively.
                  set interface gigabit-ethernet <interface-name> family ethernet-switching port-mode <port-mode>
                  set interface gigabit-ethernet <interface-name> family ethernet-switching vlan members <vlan-id>
Step2 Â Â Â Â Â Â Â Enable IGMP snooping globally.
                  set protocols igmp-snooping enable true
Step3 Â Â Â Â Â Â Â Configure mrouter port.
                  set protocols igmp-snooping vlan-id <vlan-id> mrouter interface <interface-name>
Step4 Â Â Â Â Â Â Â Configure MVR source group.
                  set protocols igmp-snooping vlan-id <vlan-id> mvr source group <multicast-network-address>/<prefix-length>
Step5 Â Â Â Â Â Â Â Configure receiver VLAN list.
                  set protocols igmp-snooping vlan-id <vlan-id> mvr receiver vlan-list <vlan range string>
Step6 Â Â Â Â Â Â Â Commit the configuration.
                  commit
Step7 Â Â Â Â Â Â Â View the configuration information of MVR.
                  run show igmp-snooping mvr mvlan <vlan-id>
                  run show igmp-snooping mvr receiver-vlan <vlan-id>
Configuration ExampleÂ
Networking Requirements
Switch B is one node of the ERPS ring, of which VLAN 100 is the ring instance member (Please refer to ERPS section for how to configure the ERPS ring and instance). The two ports, te-1/1/1/1 and te-1/1/2 are ring port0 and port1, both are mrouter ports as well.
Figure 1. MVR Configuration Example
Port te-1/1/10, te-1/1/11 and te-1/1/12 are the access ports with VLAN ID as 101, 102 and 103 respectively.
Procedure
Switch B
Step1Â Â Â Â Â Â Â Â Â Enable IGMP snooping globally.
admin@SwitchB# set protocols igmp-snooping enable true
Step2 Â Â Â Â Â Â Â Configure upstream mrouter ports.
admin@SwitchB# set interface gigabit-ethernet te-1/1/1 family ethernet-switching native-vlan-id 100Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â admin@SwitchB# set interface gigabit-ethernet te-1/1/2 family ethernet-switching native-vlan-id 100 admin@SwitchB# set protocols igmp-snooping vlan-id 100 mrouter interface te-1/1/1 admin@SwitchB# set protocols igmp-snooping vlan-id 100 mrouter interface te-1/1/2
Step3 Â Â Â Â Â Â Â Configure MVLAN and source groups.
admin@SwitchB# set protocols igmp-snooping vlan-id 100 mvr source group 225.0.0.1/32
Step4 Â Â Â Â Â Â Â Configure access ports.
admin@SwitchB# set interface gigabit-ethernet te-1/1/10 family ethernet-switching port-mode trunk admin@SwitchB# set interface gigabit-ethernet te-1/1/10 family ethernet-switching vlan members 101 admin@SwitchB# set interface gigabit-ethernet te-1/1/11 family ethernet-switching port-mode trunk admin@SwitchB# set interface gigabit-ethernet te-1/1/11 family ethernet-switching vlan members 102 admin@SwitchB# set interface gigabit-ethernet te-1/1/12 family ethernet-switching port-mode trunk admin@SwitchB# set interface gigabit-ethernet te-1/1/12 family ethernet-switching vlan members 103
Step5 Â Â Â Â Â Â Â Configure MVR receiver VLAN IDs.
admin@SwitchB# set protocols igmp-snooping vlan-id 100 mvr receiver vlan-list 101-103
Step6 Â Â Â Â Â Â Â Commit the configurations.
admin@SwitchB# commit
Verifying the Configuration
- The command run show igmp-snooping mvr mvlan <vlan-id> can be used to check the MVLAN(s) of the MVR.
admin@SwitchB# run show igmp-snooping mvr mvlan 100 Mvlan    Receiver-vlan -------- ------------------ 100    101, 102, 103
- The command run show igmp-snooping mvr receiver-vlan <vlan-id> will show the receiver VLAN and MVR VLAN information.
admin@SwitchB# run show igmp-snooping mvr receiver-vlan 101 Receiver-vlan  Mvlan ------------- ---------- 101       100
- You can use the run show igmp-snooping groups command to show information about multicast group member ports which is used for Layer 2 forwarding, namely, the Layer 2 forwarding table.  Port List shows the egress ports for multicast packets.
admin@SwitchB# run show igmp-snooping groups Vlan     Group           Port List         Type -------- ------------------      -----------------  ---------------------- 100      225.0.0.1       te-1/1/10          Dynamic                                      te-1/1/11          Dynamic te-1/1/1          MrouterÂ
