SNR S2940-8G-v2 Switch Configuration Guide
IPv6 Multicast Protocol
program 1 while the host connected to port 10 playing program 2, and the one to port 12 playing
program 3.
MLD Snooping interception results:
The multicast table on vlan 100 shows: port 1, 2, 6 are in (Multicasting Server 1, Group1),
port1, 10 are in (Multicasting Server 1, Group2), and port1, 121, 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 41.2: 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 and
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)#ipv6 mld snooping
SwitchA(config)#ipv6 mld snooping vlan 60
SwitchA(config)#ipv6 mld snooping vlan 60 l2-general-querier
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
