Fig 2-3 Switch as MLD Querier Function figure
Configuration of switch B is the same as the switches in case 1, and here the switch
1 replaces the Multicast Router in case 1. Assume the vlan 60 configured on it contain
s port 1, 2, 10 and 12, amongst port 1 is connected to multicast server, port 2 to swit
ch2. To send Query periodically, global MLD Snooping has to be enabled while executi
ng the mld snooping vlan 60 l2-general-querier, setting the vlan 60 to a Level 2 Gener
al Querier.
Configuration procedure is as follows:
SwitchA#config
SwitchA(config)#ipv6 mld snooping
SwitchA(config)#ipv6 mld snooping vlan 60
SwitchA(config)#ipv6 mld snooping vlan 60 l2-general-querier
SwitchB#config
SwitchB(config)#ipv6 mld snooping
SwitchB(config)#ipv6 mld snooping vlan 100
SwitchB(config)#ipv6 mld snooping vlan 100 mrouter interface ethernet 1/0/1
Multicast configuration:
Same as scenario 1
MLD Snooping interception results:
Same as scenario 1
Scenario 3: To run in cooperation with layer 3 multicast protocols
SWITCH which is used in Scenario 1 is replaced with ROUTER with specific config
urations remains the same. And multicast and IGMP snooping configurations are the sa
me with what it is in Scenario 1. To configure PIM-SM6 on ROUTER, and enable PIM-
SM6 on vlan 100 (use the same PIM mode with the connected multicast router)
The configurations are listed as below:
switch#config
switch(config)#ipv6 pim multicast-routing
switch(config)#interface vlan 100
switch(config-if-vlan100)#ipv6 pim sparse-mode
MLD snooping does not distribute entries when layer 3 multicast protocol is enable
d. It only does the following tasks.
 To remove the layer 2 multicast entries.
 To provide query functions to the layer 3 with vlan, S, and G as the parameters.
 When layer 3 MLD is disabled, re-enable distributing layer 2 multicast entries.
