Configure simulated joining
Each simulated host is equivalent to an independent host. For example, when
■
receiving an MLD query, the simulated host corresponding to each
configuration responds respectively.
Unlike a static member port, a port configured as a simulated member host will
■
age out like a dynamic member port.
The fast leave processing feature allows the switch to process MLD done messages
in a fast way. With the fast leave processing feature enabled, when receiving an
MLD done message on a port, the switch immediately removes that port from the
outgoing port list of the forwarding table entry for the indicated IPv6 multicast
group. Then, when receiving MLD done multicast-address-specific queries for that
IPv6 multicast group, the switch will not forward them to that port.
In VLANs where only one host is attached to each port, fast leave processing helps
improve bandwidth and resource usage.
