NOTE:
•
The reset mld-snooping group command works on only an MLD snooping–enabled VLAN, but cannot
work on a VLAN with MLD enabled on its VLAN interface.
• The reset mld-snooping group command cannot remove the static group entries of MLD snooping
groups.
• For more information about the display mac-address multicast command, see the IP Multicast
Command Reference.

IPv6 group policy and simulated joining configuration example
Network requirements
• As shown in Figure 24 , Router A connects to the IPv6 multicast source through Ethernet 1/0/2 and
to Switch A through Ethernet 1/0/1. Router A is the MLD querier on the subnet.
• MLDv1 runs on Router A, MLDv1 snooping runs on Switch A, and Router A acts as the MLD querier
on the subnet.
• The receivers, Host A and Host B, attached to Switch A can receive IPv6 multicast traffic addressed
to IPv6 multicast group FF1E::101 only.
• IPv6 multicast data for group FF1E::101 can be forwarded through Ethernet 1/0/3 and Ethernet
1/0/4 of Switch A even if Host A and Host B accidentally, temporarily stop receiving IPv6 multicast
data.
