Wireless Multicast Forwarding – Everything You Need to Know
The Wireless Multicast Forwarding feature forwards the multicast traffic in wireless devices. It helps the users to overcome the multicast transmission issues on the network. WMF uses IGMP technology to keep track of all the participants in the group.
This feature is enabled in situations when the hosts need to receive a multicast. You can boost the Wi-Fi performance using Wireless Multicast Forwarding (WMF). However, you must set up the WAP device before enabling this wireless feature. Otherwise, the device can’t forward traffic on the Wi-Fi network.
Now, let’s get to know more about the wireless multicast forwarding (WMF) feature:
Why Should You Use the Wireless Multicast Forwarding Feature?
WAP device users can transfer data safely over the internet when WMF is on because frames are sent as unicast in this wireless mode.
