The multicast ipv6 routing-enable command enables IPv6 multicast.
The undo multicast ipv6 routing-enable command restores the default configuration.
By default, IPv6 multicast is not enabled. If IPv6 multicast is not enabled, the router cannot forward IPv6 multicast packets.
Usage Scenario
Other IPv6 multicast-related commands can be run only after the IPv6 multicast function is enabled.
Precautions
Running the undo multicast ipv6 routing-enable command will clear all IPv6 multicast configurations and terminate the running IPv6 multicast services. To restore the IPv6 multicast services, you need to reconfigure the deleted commands.
