Overview
An IPv6 router uses the MLD protocol to discover the presence of multicast listeners on the directly
attached subnets. Multicast listeners are nodes wishing to receive IPv6 multicast packets.
Through MLD, the router can learn whether any IPv6 multicast listeners exist on the directly connected
subnets, put corresponding records in the database, and maintain timers related to IPv6 multicast
addresses.
Routers that run MLD use an IPv6 unicast link-local address as the source address to send MLD messages.
MLD messages are ICMPv6 messages. All MLD messages are confined to the local subnet, with a hop
count of 1.
The term "router" in this document refers to both routers and routing-capable firewalls and UTM devices.
MLD can be configured only at the CLI.
1014BMLD configuration task list
For the configuration tasks in this section, the following rules apply:
• In MLD view, the configuration is effective globally. In interface view, the configuration is effective
on only the current interface.
• The configurations made in interface view take precedence over those in MLD view. If you do not
make a configuration in interface view, the global configuration in MLD view applies to that
interface.
Complete these tasks to configure MLD:
