For the Cisco router security configuration command family, the following are 10 configuration commands, which are expected to be good for everyone. When talking about configuring a new Cisco router, most configurations depend on the type of the router and the purpose of the service. However, each administrator has his/her own command list for configuring each
Router is the bridge of computer network, is the core device of connecting IP network. It can not only connect different networks, but also choose the path of data transmission, and can block illegal access. Routers are data packet forwarding devices that work in the third layer of the OSI Reference Model-the network layer, and routers implement network interconnection by forwarding packets. For beginners, routers are not easy to configure. This paper
First, Introduction HSRP (hot Standby Router Protocol Thermal Backup Router protocol) is a proprietary protocol of Cisco. HSRP makes up a "hot backup group" of multiple routers, forming a virtual router. Only one router in this group is active (active), and it forwards the packets, and if the active
At present, PE routers are widely used. They are one type of VPN routers. So I have studied the explanations and principles of PE routers and will share them with you here, I hope it will be useful to you. VPNVirtual Private Network (VPNVirtual Private Network) is a virtual Private Network based on public networks. It uses tunneling, encryption, and other technologies to provide users with a sense of direct connection to the Private LAN.

When information needs to be transferred between two networks, the interconnection device of common routers is responsible for the transmission of data. The main work of the router is: The decision of the path and the forwarding of the packet (from the router an interface input, and then select the appropriate interface output); Maintenance path by the table.The way the
