Abstract: Presented herein are techniques to address a lack of path maximum transmission unit discovery in the context of, e.g., the control and provisioning of wireless access point (CAPWAP) protocol for multicast communications. In one embodiment, IPv4-IPv6-IPv4 network address translation is used to avoid a conservative maximum transmission unit size. In another embodiment, unicast and multicast path maximum transmission unit discovery techniques are executed to set the maximum transmission unit size for multicast communications.
