STEP 7 Ensure that an IGMP Mrouter interface has been configured for this VLAN (or all
VLANs). See Configuring IGMP Multicast Router Interfaces.
Configuring MLD Snooping
MLD is a protocol used by IPv6 multicast routers to discover the presence of
multicast listeners (nodes wishing to receive IPv6 multicast packets) on its
directly-attached links and to discover which multicast packets are of interest to
neighboring nodes. MLD is derived from IGMP, which performs a similar function
for IPv4 multicast traffic (see Configuring IGMP Snooping).
When MLD snooping is enabled, the switch selectively forwards IPv6 multicast
packets to a list of ports that want to receive the data instead of flooding the
packets to all ports in the VLAN. This list is constructed by snooping IPv6 multicast
control packets.
NOTE The switch supports MLD snooping of MLD version 1 and version 2 packets. The
switch can be configured to perform MLD snooping and IGMP snooping
simultaneously.
MLD snooping can be enabled or disabled separately on each VLAN. Although
MLD is based on IPv6 addresses, the switch performs the actual multicast
forwarding based on the equivalent MAC addresses.
To enable and configure MLD snooping:
STEP 1 Click Multicast > MLD Snooping in the navigation window.
The MLD Snooping Table lists each VLAN on which this feature is enabled.
STEP 2 Select Enable for the MLD Snooping Status.
STEP 3 Click Add in the MLD Snooping Table.
