Configuring simulated joining
Generally, an MLD-enabled host can responds to MLD queries that the MLD querier sends. If a host fails
to respond, the multicast router deems that no member of this IPv6 multicast group exists on the network
segment, and removes the corresponding forwarding path.
To avoid this situation, you can enable simulated joining on a port of the access controller. Namely, you
configure the port as a simulated member host for an IPv6 multicast group. When the simulated member
host receives an MLD query, it gives a response. Therefore, the access controller 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 access controller 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 function is disabled on a port, the access controller sends an MLD done
message through that port.
