hi Matt.
mappings to the remote link local, are needed when you are running a dynamic
routing protocol.
I mean if you are running ipv6 over frame relay and you are using static
routes .. there is no need for mapping. Contrary if you arr running ospv3
where you need mapping.
Now broadcast option can be set in remote link local, or remote ipv6
address, both ways work. I have tested and both ways work for the dynamic
routing to work sending multicast depending the dynamic routing protocol you
are using.
Try using broadcast option, unless otherwise specified.
