A network device includes processing circuitry and multiple ports. The multiple ports are configured to connect to a communication network. The processing circuitry is configured to select a first port among the multiple ports to serve as an egress port for a packet, and to forward the packet to the first port, irrespective of whether or not the first port is usable as the egress port. The processing circuitry is further configured to, when the first port is usable as the egress port, transmit the packet to the communication network via the first port, and when the first port is unusable as the egress port, forward the packet from the first port to a second port among the multiple ports and transmit the packet to the communication network via the second port.
