Caution
The Multicast Group Access Control is associated with Extended ACL. When
the MLD report message received is (S1,S2,S3…Sn,G), this command will
perform the corresponding ACL based check of (0,G) information. Therefore,
an explicit entry of (0,G) shall be configured for extended ACL to allow the
normal filtering of (S1,S2,S3…Sn,G). This (0,G) mentioned herein refers to all
sources of the specific group.
4.2.10 Configure Immediate Leave Group
In MLD, this command can reduce the leave latency. When there is only one host
on the attached link needs to receive group information, after the host sends out
the leave message, it can leave immediately without the need for the querier to
device to send group-specific query. This command is used when one interface
has only one receiver host.
