Configuring a port as a simulated member host
Generally, a host that runs MLD can respond to MLD queries. If a host fails to respond, the multicast router
might deem that the IPv6 multicast group has no members on the subnet, and removes the corresponding
forwarding path.
To avoid this situation, you can configure a port on the switch as a simulated member host for an IPv6
multicast group. A simulated host is equivalent to an independent host. For example, when a simulated
member host receives an MLD query, it gives a response separately. Therefore, the switch can continue
receiving IPv6 multicast data.
A simulated host acts like a real host in the following ways:
•
When a port is configured as a simulated member host, the switch sends an unsolicited MLD report
through the port, and can respond to MLD general queries with MLD reports through the port.
•
When the simulated joining configuration is canceled on the port, the switch sends an MLD done
message through that port.
