Huawei quidway s7700 - Example for Configuring Multicast VLAN Replication Based on User Vlans

3.5.1 Example for Configuring Multicast VLAN Replication Based
on User VLANs
Networking Requirements
As shown in Figure 3-4, RouterA is connected to the multicast source. GE1/0/0 of RouterA is
connected to GE1/0/0 of SwitchA. GE1/0/0 of SwitchA belongs to VLAN 10. HostA, HostB,
and HostC are connected to GE1/0/1, GE1/0/2, and GE1/0/3 of SwitchA and belong to VLAN
100, VLAN 200, and VLAN 300 respectively.
To save network bandwidth, you can configure multicast VLAN replication based on user
VLANs on SwitchA. RouterA then only needs to send one copy of multicast data to the multicast
VLAN, and SwitchA distributes multicast data to user VLANs.

Configuration Roadmap
The configuration roadmap is as follows:
1. Enable IGMP snooping globally.
2. Create a multicast VLAN and enable IGMP snooping in the multicast VLAN.
3. Create user VLANs.
4. Bind the user VLANs to the multicast VLAN.
5. Add the network-side interface and user-side interfaces to VLANs as hybrid interfaces.
