I. Overview:
In actual work, it is estimated that two ISP lines, such as China Telecom and China Netcom, are often connected using ASA, and there is not enough budget to buy load balancing equipment, however, we want to achieve load sharing and automatic switching of links. We want to return traffic from China Telecom, from China Telecom to China Telecom, and from China Netcom to China Telecom. When one of the lines fails, all traffic never goes throu
