MLD snooping configuration examples
IPv6 group policy and simulated joining configuration
example
Network requirements
As shown in
, Router A runs MLDv1 and acts 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 IPv6 multicast group
FF1E::101. IPv6 multicast data can be forwarded through GigabitEthernet 1/0/3 and
GigabitEthernet 1/0/4 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.
