For example, it's the normal way multicast applications work; see
IPV6_MULTICAST_IF in ip6(7D).
I was actually expecting the interface index to be tied in
(somehow) with the IPv6 scope identifier but I couldn't
easily find anything in Solaris to join those two concepts,
so I put that idea aside. But I'm not in the least bit
surprised to see it show up here.
But this isn't exactly what I'd call "mainstream" - there
isn't a hell of a lot of either IPv6 or multicast use today,
so I imagine that the multicast IPv6 use is an even
smaller set.
That said, there should be a comment added to ip6(7p)
for IPV6_MULTICAST_IF, mentioning that the interface
index for an interface can change and if an application
is interested in this event, it should be on the lookout
with a routing socket. See 6430864.
