Enable Wireless Multicast Forwarding (WMF) on a Wireless Access Point (WAP)


Wireless Multicast Forwarding (WMF) is an efficient way to forward traffic on the wireless network. It overcomes transmission issues by transmitting traffic only to the targeted members of the multicast. WMF uses Internet Group Management Protocol (IGMP) to keep track of the participants of the group. It is commonly enabled in situations when there only interested hosts need to receive a multicast. Enabling this feature is useful to improve wireless connectivity in your network.

This article aims to show you how to enable wireless multicast forwarding on a wireless access point (WAP).
