Methods and systems for fast and reliable network recovery from multiple link failures. In accordance with one example of the method, a master node receives a request from a transit node having a blocked port to open the blocked port for data forwarding, wherein the blocked port is associated with a restored link. The master node starts a health-check timer and transmits a health-check message on its primary port to determine that all failed links of the network are restored. Upon determining that the health-check message is received at its secondary port, the master node transmits a message to each transit node indicating that all failed links are restored. Upon determining that the health-check message is not received at its secondary port before the health-check timer lapsed, the master node transmits a message to the transit node to open the blocked port associated with the restored link for data forwarding.
