Moreover, the servo motor has the characteristics of strong adaptability, high stability and good dynamic performance, which is suitable for the high-speed and precise reaction o

Two-line access technology for Cisco Routers

Two-line access technology for Cisco Routers In some cases, we need to implement dual-line access to ensure stable operation of the network and ensure reliable service quality. The following steps can be taken: 1. Configure the IP address of the Internet access interface, which is generally from China Telecom or China Netcom. 2. Configure the access control list 3. Configure the NAT address pool 4. Configure the route-map table 5. Configure NAT 6. Set the default route Step 1: Configure the
