multicast

[admin]

If the switch has multicast groups enabled and the switch was restarted it can lose the group table and multicast won't work. Try connecting to the nearest switch of any LM and check if multicast is passed there or not.

For multicast to work correctly on Mikrotik you need to enable both "IGMP snooping" and "Multicast Querier". This way the switch will periodically send multicast group queries and will update internal tables correctly.
