Configuring a Static Router Port
In a network where the topology is unlikely to change, you can configure a port on the device as a static
router port, so that the device has a static connection to a multicast router and receives IGMP
messages from that router.

Configuring a Port as a Simulated Group Member
Generally, hosts running IGMP respond to the IGMP query messages of the multicast device. If hosts
fail to respond for some reason, the multicast device may consider that there is no member of the
multicast group on the local subnet and remove the corresponding path.
To avoid this from happening, you can configure a port of the VLAN of the device as a multicast group
member. When the port receives IGMP query messages, the multicast device will respond. As a result,
the port of the VLAN can continue to receive multicast traffic.
Through this configuration, the following functions can be implemented:
