• 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.
To enable MLD:

For more information about the multicast ipv6 routing-enable command, see IP Multicast Command
Reference.
Configuring the MLD version
Because MLD message types and formats vary with MLD versions, the same MLD version should be
configured for all routers on the same subnet before MLD can work properly.

Configuring static joining
After an interface is configured as a static member of an IPv6 multicast group or an IPv6 multicast source
and group, it will act as a virtual member of the IPv6 multicast group to receive IPv6 multicast data
addressed to that IPv6 multicast group for the purpose of testing IPv6 multicast data forwarding.
