NOTE

In this example, an MLDv1 group is in EXCLUDE mode with a source of 0. The group excludes traffic from the 0 (zero) source list, which actually means that all traffic sources are included.

To display detailed MLD group information, enter the following command.

Device#show ipv6 multicast group ff0e::ef00:a096 detail Display group ff0e::ef00:a096 in all interfaces in details.
