Each line shows one (S,G) entry in the multicast routing cache,
where S is the source address and G is the multicast group. Iif is
the interface on which multicast packets are expected to arrive.
If the word unresolved is there instead of the interface name,
it means that the routing daemon still hasn't resolved this entry.
The keyword oifs is followed by a list of output interfaces, separated
by spaces. If a multicast routing entry is created with non-trivial
TTL scope, administrative distances are appended to the device names
in the oifs list.
