Hi, dear user.
You can refer to the following steps:
Create a virtual local area network (VLAN) profile 3 (assume that the VLAN ID is 3), set the VLAN forwarding mode to vlan-connect, and set the forwarding policy for unknown multicast packets to forward (direct forwarding). The commands are as follows:
huawei(config)#vlan service-profile profile-id 3
huawei(config)#forwarding vlan-connect
huawei(config)#packet-policy multicast forward
huawei(config)#commit
Bind the VLAN profile to the upstream VLAN to make the configuration take effect. Assume that the upstream VLAN ID is 3999. The configuration command is as follows:
huawei(config)#vlan bind service-profile 3999 profile-id 3
You are advised to disable the multicast traffic suppression function on the user port. Assume that the user port is 0/1/3. The configuration command is as follows:
huawei(config)#interface eth 0/1
huawei(config-if-eth-0/1)#undo traffic-suppress 3 multicast
Hopes can help you.
