I think he's talking about the multicast helper which is in the Wireless (and CAPSMAN) system which does multicast to unicast conversion at the radio interface. It's needed to make things like mDNS and DHCP more reliable and also allow for use of VLANs with wireless clients. I am surprised it doesn't exist in WifiWave2.
Search for it in https://help.mikrotik.com/docs/display/ ... +Interface
So yeah, FTOMs what's the go with multicast to unicast conversion in WifiWave2? Does it exist in some other form?
- wireless driver: "multicast-helper: When set to full, multicast packets will be sent with a unicast destination MAC address, resolving multicast problem on the wireless link." https://help.mikrotik.com/docs/display/ ... +Interface
- wifi driver: "multicast-enhance: With the multicast-enhance feature enabled, an AP will convert every multicast-addressed IP or IPv6 packet into multiple unicast-addressed frames for each connected station." https://help.mikrotik.com/docs/display/ROS/WiFi
Layer 2 is implied as they use the keyword "frame" in the multicast-enhance description. And they imply layer 3 (IP) as they use "packet" in multicast-helper description. So according to the docs it should IMHO do the same.
