In embodiments in which one or more multicast packets are utilized to transmit network security information, the network security information is included in media access control (MAC) header(s) of the one or more multicast packets, e.g., in information elements (IE) included in the MAC header(s). In embodiments in which one or more multicast packets are utilized to transmit network security information, the device 22 generates the one or more multicast packets to have one or more multicast addresses that the device 32 is configured to recognize as corresponding to packets having network security information. For example, in some embodiments, the device 32 is configured to determine whether the multicast packet(s) has address(es) in a range that the device 32 is configured to recognize as corresponding to corresponding to packets having network security information. In an embodiment, when the device 32 determines that the multicast packet(s) has an address(es) corresponding to packets having network security information (e.g., is determined to be within a particular range of addresses, is determined match one or more particular addresses, etc.), the device 32 then goes forward with extracting network security information from the packet(s). On the other hand, in an embodiment, when the device 32 determines that the multicast packet(s) does not have an address(es) corresponding to packets having network security information, the device 32 ignores the packet(s).
