The OSPF routing protocol is a classic link-state routing protocol typically used within the same routing domain. In this context, a routing domain refers to an Autonomous System (AS), which is a group of networks that exchange routing information with each other through a unified routing policy or routing protocol. Within this AS, all OSPF routers maintain a …
For wireless networks today, the biggest impact undoubtedly comes from wireless interference, which severely degrades network stability and transmission speed. As the use of wireless networks continues to expand in daily life, instances of wireless interference are also constantly occurring. First, large-scale WLAN networks generally adopt a thin AP architecture. For wireless interference…
This article introduces two network connection methods for Huawei routers: bridge mode and routing mode. If you’re unfamiliar with these concepts, by the end of this guide you’ll know exactly how to configure both types of network connections. 1. Bridge Mode 1. The formal, professional term for bridge mode is RFC 1483 Bridging. …

If you’re not familiar with IP and router concepts, this article will teach you something new. When a router receives a data packet with an unknown router IP address, it will attempt to send an ARP broadcast to resolve it. If a target host responds to this ARP broadcast, the router will forward the data packet to that target host …
The following is an experiment using the SSH protocol to manage a router, a small but very practical technique in real-world work. The network topology consists of an SSH server R1 connected to an SSH client router R2, with an SSH client PC bridged in between. 1. Telnet is very simple; just set up a password, then lo …
When building networks with routers, a DNS server is an essential public service. Today, we鈥檒l walk you through the installation and configuration of a DNS server on a Linux system. The network topology consists of three DNS servers (acting as the primary DNS, subordinate DNS, and secondary DNS) and one DNS test client, connected by a router.
When setting up a new broadband connection or adding a new device to your network, you often run into “IP address conflict” or DNS issues. These are not hardware failures of the router or the computer’s network card, but rather problems with IP address configuration and subnet segmentation. In a simple network, as long as you…
Whether at school, home, or the office, encountering ISP blocks on router sharing can cause major obstacles to everyday internet access. As the saying goes, while the devil climbs a foot, the priest climbs ten 鈥?skilled experts have still found ways to bypass these restrictions. Below, we share several methods to crack ISP router sharing limits. Already …
VPN may not be common in home networks, but for an enterprise network, VPN is a critically important component 鈥?it ensures the security and stability of corporate data transmission. This article uses Huawei routers as an example to introduce VPN knowledge. Currently, VPN generally uses two connection methods …
