I think this has been discussed a bit earlier with reference to multicast
solutions and multiple maps pointing to the same DLCI. I would likely have
to sit on a network with a sniffer to give you a 100% answer, but I can tell
you easily enough that IPv6 works with a lot of multicast operations.
Everything I have seen (at least what I've paid attention to) uses the
link-local address as the source, so with that in mind, I would say it would
be necessary to put the "broadcast" parameter on that one map.
I have not noticed any multicasts originated with the global unicast
addresses to this point, so I don't believe that would be necessary.
Other than being inefficient (which in the lab we generally don't care)
there is no harm in putting it on multiple maps if you are unsure. But
since multicasts are a destination anyway, I would feel confident in putting
the parameter only on my link-local map for a particular DLCI.
Don't just take my word for it though, lab it up and run some debugs/show
commands. See what happens! Perhaps we'll all learn something and it'll be
fun!

Subject: L3 to L2 Frame-relay Map IPV6 LLAddress and Global IPV6 Address
Dears,
Do I need to use a Broadcast parameter in frame-relay map ipv6 between 2
routers that are in a multipoint interface using the ipv6 add and the Link
Local Add? or it's just enough to put the broadcast parameter in the
frame-relay map Link Local Address ?
Thanks
Zuke.
