Task
Remarks
Optional
Configuring IPv6 multicast forwarding on a
downstream interface
Optional
NOTE:
•
In MLD view, the configuration is effective globally. In interface view, the configuration is effective on
only the current interface.
•
A configuration made in interface view always has priority over the same configuration made in MLD
view. If no configuration is made in interface view, the global configuration in MLD view applies.
Configuring basic MLD functions
Configuration prerequisites
Before you configure the basic functions of MLD, complete the following tasks:
•
Enable IPv6 forwarding and configure an IPv6 unicast routing protocol so that all devices in the
domain can be interoperable at the network layer.
•
Configure IPv6 PIM-DM or IPv6 PIM-SM.
•
Determine the MLD version.
•
Determine the IPv6 multicast group address and IPv6 multicast source address for static group
member configuration.
•
Determine the ACL rule for IPv6 multicast group filtering.
•
Determine the maximum number of IPv6 multicast groups that an interface can join.
Enabling MLD
Enable MLD on the interface on which IPv6 multicast group memberships will be created and
maintained.
