Output format:

kuznet@alisa:~ $ ip maddr ls dummy
2:  dummy
    link  33:33:00:00:00:01
    link  01:00:5e:00:00:01
    inet users 2
    inet6 ff02::1
kuznet@alisa:~ $

The first line of the output shows the interface index and its name. Then the multicast address list follows. Each line starts with the protocol identifier. The word link denotes a link layer multicast addresses.

If a multicast address has more than one user, the number of users is shown after the users keyword.

One additional feature not present in the example above is the static flag, which indicates that the address was joined with ip maddr add. See the following subsection.
