Static Multicast MAC
Address Overview
Address Overview
The concept of "static multicast MAC address" is proposed to fulfill the feature of
static Layer 2 multicast. When some network users need some specific
information, the multicast information sender (the multicast source) sends the
information only once, and the multicast packets are sent to the specified port
with the help of the configured static multicast MAC address.
