impact of topology changes reduces network instability. Problems in one region do not affect other regions. OSPF neighbor and Neighbor Relationship: • The OSPF router establishes a neighbor relationship with its directly connected neighbor. • The OSPF router only transmits the LSA to the router that establishes an adjacent relationship. • A

RIP and IGRP are commonly used router configuration protocols. What problems should we pay attention to when configuring RIP and IGRP? What should we do? The following configuration steps provide detailed answers. RIP Protocol RIP (Routing information Protocol) is an Internal Gateway Protocol (IGP) that is widely used earlier and is suitable for small-sized similar networks, is a typical distance-vector protocol. For more information, see RFC1058 an

For wireless network users, it is important to know that no matter how secure the wireless network is, unless end-to-end encryption technology has been deployed, otherwise, there is no real security. Although wireless technology has many advantages in availability, wireless security cannot be compared with wired network security. DHCP-automatically obtain an IP address or a fixed IP address? DHCP (Dynamic Host Configuration Protocol) allows you to set the Protocol for a Dynamic Host to automatic

The development of wireless LAN is now very complete, and the speed is getting faster and faster. The current mainstream products not only achieve the speed of common wired Ethernet, but also have basic security assurance. More importantly, no cabling is required for wireless networking. Therefore, it is the best choice for domestic users of the consumer type. In addition to the popularity of the Chinese version, it is time for most users to purchase a wireless

, we assume that there is such a simple network. Assume that four terminal devices are connected together in the same CIDR block, and the IP addresses of each device in this CIDR block are assumed to be: a1, A2, A3, and A4. A Router connected to this CIDR block is used to connect to other CIDR blocks. the IP address of the port connecting the router to CIDR Block A is A5. Similarly, when a

In a home or small office network, a wireless router is usually directly used to achieve centralized connection and Internet sharing tasks, because the wireless router also has a collection of Wireless AP connection functions. This article will introduce the TP-LINK of a wireless router TL-WR541G in the home wireless network configuration method. A wireless

with neighboring routers, system configuration, and system management. In the past few years, the development of vrouters has continued. In the middle of 1990s, traditional routers became the bottleneck restricting the development of the Internet. Instead, the ATM switch becomes the core of the IP backbone network, and the vro becomes a secondary role. In the end of 1990s, the Internet scale was further expanded, and traffic doubled every six months. The ATM network became a bottleneck, and the
