The invention provides a network disaster tolerance method for information synchronization. A first controller and a second controller between which information synchronization can be carried out are included. By using a characteristic of a GRE tunnel, the GRE tunnel is configured on a network with intact connectivity and the highest temporary weight, the IP address couple of the GRE tunnel can be kept unchanged, and the purposes of switching the network but not influencing information synchronization and heartbeat data transmission can be achieved. 本发明提供了种用于信息同步的网络容灾方法,包括相互之间可信息同步的控制器1及控制器2，本发明利用GRE隧道的特性，在连通性完好并且暂时权重最高的网络上配置GRE隧道，可保持GRE隧道的IP地址对不变,达到切换网络而不影响信息同步以及心跳数据传输的目的。
