This article mainly introduces how to make clever configuration to make the router more convenient for us when we use the Huawei router. This article is of great help to the first contacts of the Huawei router. Huawei routers and foreign brands of the same grade have completely the same functional features and

Cisco single-ARM routing configuration One-arm routing, which is to set up multiple logical subinterfaces on the router, one VLAN for each sub-interface. The data on each sub-interface is passed on the physical link to be labeled encapsulated. Cisco devices support ISL and 802.1q (dot1q) protocols. Huawei only support

With the development of the international interconnection Network, some enterprises have established their own intranet and connected with the Internet through a dedicated line. In order to ensure the security of intranet, it is necessary to use dedicated firewall computer to prevent illegal intrusion. The router firewall can only be used as a filter and cannot hide the internal network structure from the intruder's eyes. As long as a computer on the

Abstract: This article describes the first time that the author personally contacts the Cisco PIX Firewall and summarizes ten basic configurations of the firewall. A hardware firewall is a wall between networks to prevent illegal intrusion and filter information. In terms of structure, it is simply a PC-type computer host with Flash) and firewall operating systems. Its hardware is similar to the common control machine, which is suitable for 24 hours

reason why ConfigMaker is no longer used is that this tool can only generate static configurations. The basis is that you tell it what to configure and what to configure), and then download these static configurations to the vro. However, over time, users began to want to have a network management tool that provides much more functionality than ConfigMaker. They want to get more real-time status and interface information from the vro. They want the software to create a more suitable

Introduction: like the standard OSPF protocol, the is-is protocol is a link-state dynamic routing protocol, but it is much optimized than OSPF, reducing the routing type and LSA flooding, it is also widely used in the current network.
