MLD snooping querier configuration example 
Network requirements 
As shown in Figure 70, in a Layer-2-only network environment, two multicast sources (Source 1 and 
Source 2) send IPv6 multicast data to multicast groups FF1E::101 and FF1E::102 respectively, Host A and 
Host C are receivers of multicast group FF1E::101 and Host B and Host D are receivers of multicast group 
FF1E::102.  
MLDv1 runs on all the receivers and MLDv1 snooping runs on all the switches. Switch A, which is close 
to the...

Configure an IP address and prefix length for each interface as per  Figure 71. (Details not 
 shown.) 
2. Configure Router A:

GigabitEthernet 1/0/1.

After the configuration is completed, Host A and Host B send MLD join messages addressed to 
group FF1E::101. When receiving the messages, Switch A sends a join message for the group out 
of port GigabitEthernet 1/0/1 (a router port) to Router A. Use the  display mld-snooping group 
command and the display mld group  command to display information about MLD snooping 
groups and MLD multicast groups. For example:  
# Display information about MLD snooping groups on Switch A.
