MLD snooping configuration examples
IPv6 group policy and simulated joining configuration example
Network requirements
As shown in Figure 70, Router A runs MLDv1 and serves as the MLD querier, and Switch A runs MLDv1
snooping.
Configure the group policy and simulate joining to meet the following requirements:
• Host A and Host B receive only the IPv6 multicast data addressed to the IPv6 multicast group
FF1E::101.
• IPv6 multicast data can be forwarded through GigabitEthernet 2/1/3 and GigabitEthernet 2/1/4
of Switch A uninterruptedly, even though Host A and Host B fail to receive the multicast data.
• Switch A will drop unknown IPv6 multicast data instead of flooding it in VLAN 100.
