One way is a pair of daemons that accept and retransmit multicast from
one network to another through a tunnel while ideally excluding the just
bridged traffic from retransmission. Maybe it could be done with socat
or some other fancy network proxy, though the one I dealt with ~15 years
ago was custom written inhouse. Also if the bridge causes network
weirdness, good luck. Also you may need to worry about missed or delayed
multicast due to latency or the bridge or daemons being down? Pretty
sure most of the issues were due to the (complicated, Enterprise)
software that used multicast and not the custom multicast bridge.
