Traffic routing

A traffic routing device capable of acting as a member device of a stacking system, wherein the device comprises:

• a memory and a processor to execute instructions stored in the memory to:
• receive, by a member device of a stacking system, traffic destined for a destination node;
• if there is at least one valid Equal-cost multi-path (ECMP) path associated with an address of the destination node in a forwarding table, route the received traffic to the destination node through the at least one valid ECMP path;
• otherwise, select at least one other member device of the stacking system for routing the received traffic, update an ECMP path associated with the address of the destination node in the forwarding table to a stacking link connecting the member device with the selected at least one member device, and transmit the received traffic to the selected at least one member device.
