Abstract
A system for facilitating loop-free traffic forwarding is provided. During operation, the system can operate a switch as a tunnel endpoint for a plurality of tunnels with corresponding remote endpoints. The system can determine a tunnel network identifier (TNI) associated with a respective virtual local area network (VLAN) configured at the switch. The system can then enable the TNI for a first tunnel among the plurality of tunnels for carrying traffic of the VLAN. Here, traffic of the VLAN is only forwarded over the first tunnel. Therefore, the system can prevent the rest of the plurality of tunnels from looping the traffic of the VLAN back to the switch. The system can select a second tunnel as a standby tunnel for the TNI from the rest of the plurality of tunnels. If the first tunnel is unavailable, the system can enable the TNI for the second tunnel for traffic forwarding.
