A network device determines that a frame priority of a received frame is a value corresponding to an audio video bridging (AVB) communication protocol. When the network device determines that a destination address of the frame is not included in a forwarding database, the network device prevents the frame from being enqueued in any of one or more egress queues of the network device that are reserved for packets to be transmitted via the AVB communication protocol. When the network device determines, based on determining that the destination address is included in the forwarding database, that the frame is permitted to be enqueued in one of the one or more egress queues reserved for frames that are to be transmitted according to the AVB communication protocol, the network device enqueues the frame in one of the one or more egress queues for transmission via the AVB communication protocol.
