Fig 18-4 Switches as MLD Querier Function figure
As shown above, the vlan 100 configured on the switch consists of ports 1, 2, 6, 10, 12.
Four hosts are respectively connected to 2, 6, 10, 12 while the multicast router on port 1.
Suppose we need mld snooping on vlan 100, however by default, the global mld
snooping as well as the mld snooping on each vlan are, therefore first we have to enable
the global mld snooping at the same time enable the mld snooping on vlan 100,
furthermore we need to set the port 1 of vlan 100 as a mrouter port.
Configuration procedure is as follows.
Switch#config
Switch (config)#ipv6 mld snooping
Switch (config)#ipv6 mld snooping vlan 100
Switch (config)#ipv6 mld snooping vlan 100 mrouter-port interface ethernet 0/0/1
Multicast configuration
Assume there are two multicast servers: the Multicast Server 1 and the Multicast Server
2, amongst program 1 and 2 are supplied on the Multicast Server 1 while program 3 on
the Multicast server 2, using group addresses respectively the Group 1, Group 2 and
Group 3. Concurrently multicast application is operating on the four hosts. Two hosts
connected to port 2 and 5 are playing program 1 while the host connected to port 10
