The broadcast to multicast conversion is designed to be done on the
multicast edge router going to hosts. So it SHOULD occur on a router
directly attached to the LAN where the hosts are. I haven't ever tried
implementing it on a hop-by-hop idea before though... The commands don't
appear to be structured in a fashion that would allow for that scenario.

Hi Scott,
When configuring multicast to broadcast. If multiple routers are
involved do we destination broadcast address or next hop broadcast address.
Thanks
