For example, when receiving an MLDquery, the simulated host corresponding to each configuration responds respectively.z Unlike a static member port, a port configured as a simulated member host will age out like adynamic member port.Configuring Fast Leave ProcessingThe fast leave processing feature allows the switch to process MLD done messages in a fast way. Withthe fast leave processing feature enabled, when receiving an MLD done message on a port, the switchimmediately removes that port from the outgoing port list of the forwarding table entry for the indicatedIPv6 multicast group. Then, when receiving MLD done multicast-address-specific queries for that IPv6multicast 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 bandwidthand resource usage.Configuring fast leave processing globallyFollow these steps to configure fast leave processing globally:To do...
