MLD Snooping interception results:
The multicast table on vlan 100 shows: port1, 2 and 6 are in (Multicasting Server 1, Group1), port1, 10 are
in (Multicasting Server 1,Group2), and port1, 12 are in (Multicasting Server 2, Group3)
All the four hosts successfully receive programs they are interested in. port2, 6 receives no traffic from
program2 and 3; port10 receives no traffic from program 1 and 3, and port12 receives no traffic from
program1 and 2.
Scenario 2: MLD L2-general-querier
Figure 22-2 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 contains port 1, 2, 10, 12, amongst port 1 is connected
to multicast server, port 2 to switch2. To send Query periodically, global MLD Snooping has to be enabled
while executing the mld snooping vlan 60 l2-general-querier, setting the vlan 60 to a Level 2 General 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
