Verifying the configuration
# Send MLD reports from Host A and Host B to join the IPv6 multicast groups FF1E::101 and FF1E::202.
(Details not shown.)
# Display information about the dynamic MLD snooping forwarding entries in VLAN 100 on Switch A.
[SwitchA] display mld-snooping group vlan 100
Total 1 entries.
VLAN 100: Total 1 entries.
(::, FF1E::101)
Host slots (0 in total):
Host ports (2 in total):
GE2/1/3 (00:03:23)
GE2/1/4 (00:04:10)
The output shows the following information:
• Host A and Host B have joined the IPv6 multicast group FF1E::101 through the member ports
GigabitEthernet 2/1/4 and GigabitEthernet 2/1/3 on Switch A, respectively,.
• Host A and Host B have failed to join the multicast group FF1E::202.
Static port configuration example
Network requirements
As shown in Figure 71:
• Router A runs MLDv1 and serves as the MLD querier, and Switch A, Switch B, and Switch C run
MLDv1 snooping.
• Host A and Host C are permanent receivers of the IPv6 multicast group FF1E::101.
Configure static ports to meet the following requirements:
• To enhance the reliability of IPv6 multicast traffic transmission, configure GigabitEthernet 2/1/3
and GigabitEthernet 2/1/5 on Switch C as static member ports for the IPv6 multicast group
FF1E::101.
