Configure the subtending multicast service.

In the MSTP ring network, MA5600-1 is subtended with Huawei MA5600, and MA5600-3 is subtended with MA5600-4. According to the data plan, MA5600-4 provides the multicast service. In this manner, it is necessary to configure the multicast subtending on MA5600-1 first.

Add the upstream port.

The upstream port is already added in 11.c. It is unnecessary to configure it again.

Configure the IGMP proxy.

The IGMP proxy is already configured in 11.c. It is unnecessary to configure it again.

Configure the program library.

The program library is already configured in 11.c. It is unnecessary to configure it again.

Configure the multicast for the subtending port.

Specify a subtending port.

huawei(config-btv)#igmp cascade-port 0/7/1

huawei(config-btv)#igmp cascade-port 0/7/2

Modify the subtending port.

huawei(config-btv)#igmp cascade-port modify 0/7/1 static enable

huawei(config-btv)#igmp cascade-port modify 0/7/2 static enable

Add programs to the static subtending port.

huawei(config-btv)#igmp static-join cascade-port 0/7/1 ip 224.1.1.1 sourceip 192

.168.1.2

huawei(config-btv)#igmp static-join cascade-port 0/7/1 ip 224.1.1.2 sourceip 192

.168.1.2

huawei(config-btv)#igmp static-join cascade-port 0/7/1 ip 224.1.1.3 sourceip sourceip 192.168.1.2

huawei(config-btv)#igmp static-join cascade-port 0/7/2 ip 224.1.1.1 sourceip sourceip 192.168.1.2

huawei(config-btv)#igmp static-join cascade-port 0/7/2 ip 224.1.1.2 sourceip 192.168.1.2

huawei(config Huawei MA5683T -btv)#igmp static-join cascade-port 0/7/2 ip 224.1.1.3 sourceip 192.168.1.2
