R2511-HP MSR Router Series IP Multicast Command Reference(V5)

279
undo fast-leave
Default
MLD fast-leave processing is disabled. That is, the MLD querier sends multicast-address-specific queries
or multicast-address-and-source-specific queries after receiving an MLD done message from a host,
instead of sending a leave notification directly to the upstream.
Views
MLD view
Default command level
2: System level
Parameters
acl6-number: Specifies a basic IPv6 ACL in the range of 2000 to 2999. The fast-leave processing
function is effective only on the IPv6 multicast groups that match the permit statement in the ACL. If you
do not include this option in your command, this command takes effect on all IPv6 multicast groups.
Usage guidelines
This command cannot be used in VLAN interface view.
You can use either the fast-leave (MLD-snooping view) command or the mld-snooping fast-leave
command to configure fast leave on Layer 2 ports.
The fast-leave (MLD-snooping view) command or the mld-snooping fast-leave command are both
effective on VLANs with MLD-enabled VLAN interfaces.
Examples
# Enable MLD fast-leave processing globally.
<Sysname> system-view
