mld group-policy

Syntax
mld group-policy acl6-number [ version-number ]
undo mld group-policy
View
Interface view
Default Level
2: System level
Parameters
acl6-number: Number of a basic or advanced IPv6 ACL, in the range of 2000 to 3999. The source
address or address range specified in the advanced IPv6 ACL rule is the IPv6 multicast source
address(es) specified in MLDv2 reports, rather than the source address in the IPv6 packets. The
system assumes that an MLDv1 report or an MLDv2 IS_EX or TO_EX report that does not carry an IPv6
multicast source address carries a IPv6 multicast source address of 0::0.
version-number: MLD version number, 1 or 2. If you do not specify an MLD version, the configured
group filter will be effective for MLD reports of both version 1 and version 2.
Description
Use the mld group-policy command to configure an IPv6 multicast group filter on the current interface
to limit access to the IPv6 multicast group.
Use the undo mld group-policy command to remove the configured IPv6 multicast group filter.
By default, no IPv6 multicast group filter is configured by default, that is, a host can join any valid IPv6
multicast group.
Examples
# Configure an IPv6 ACL so that hosts on the subnet attached to Vlan-interface1 can join the IPv6
multicast group FF03::101 only.
