2. Overview

  • IGMP snooping can forward multicast traffic only in the same VLAN. If multicast traffic needs to be forwarded to different VLANs, the multicast source must send multicast traffic to different VLANs. To save uplink bandwidth and reduce the burden on multicast sources, Multicast VLAN Registration (MVR) was developed. MVR can copy multicast traffic received from an MVR VLAN and forward it to the VLAN where the user resides.
  • It corresponds to IGMP Snooping Functions in SVGL mode on RG-CS series switches.
3. Configuration Procedure

3.1 Configuration Requirements

In the multicast network shown in Figure 1, the router (Device A) connects to the user network through the switch (Device B). IGMP snooping is enabled on Device A,which is directly connected to the multicast source. The multicast source sends data to the multicast group 225.0.0.10. Host A, Host B, and Host C are in VLAN 101, VLAN 102, and VLAN 103, respectively, and all three hosts have joined the multicast group 225.0.0.10. As a result, Host A, Host B, and Host C can receive multicast data sent by the multicast source to this group.
3.2 Topology


3.3 Configuration Notes

  • Configure basic IGMP snooping functions on Device B.
  • Configure the IP addresses, VLANs, and unicast routing protocols of the network nodes to ensure reachability of the network nodes using unicast routing.
  • Enable multicast routing and PIM-SM related functions on Device A.
  • Enable IGMP snooping and run the SVGL mode on Device B.
  • Configure the multicast groups associated wit the IGMP snooping SVGL mode on Device B and specify the shared VLAN and sub VLANs.
3.4 Configuration Examples

1. Configure the IP addresses, VLANs, and unicast routing protocols of the network nodes to ensure reachability of the network nodes using unicast routing. Configure the IP address and unicast routing protocol on Device A.
