There are many things worth learning about in the configuration of a Cisco Wireless Router. Here we mainly introduce how to use a vro to set up a PC to share the Internet, including knowledge about DHCP, security, TCP/IP network protocols, and so on.
As a product designed specifically for broadband Internet sharing, a Broadband Router has the advantages of simple and convenient Internet sharing, high security, flexibility and reliability, more and mor
Cisco, as a leader in the routing industry, has a high demand for its products in the market. Here we will explain how to effectively reinforce the security of Cisco routers. According to the barrel theory, how much water a bucket can hold depends on the shortest piece of wood in the bucket. The same is true for information system security. The security level of the entire information system depends on the
At present, there are many users using CISCO routers, so today we will introduce in detail the main steps for configuring the CISCO Router password and what we need to pay special attention to. I hope this will help you, I hope you will learn more after reading the article. In CISCO router products, we usually need to restrict the access of general users during i
Many people may not have a special understanding of Cisco router configuration, so I have studied the detailed knowledge of Cisco router configuration. I will share it with you here, hoping it will be useful to you. Have you ever encountered a situation where you have modified the Cisco router or vswitch and need to remove the modifications? There are many ways t

Cisco router security-TCP connections are common attacks on the network. In fact, most attacks are based on TCP connections, and a large amount of request data is sent to cause Server Denial of Service, is a connection attack. Next, I will take a Cisco router as an example to introduce how to intercept illegal TCP connections. In the so-called three-way handshake of TCP connection, the first packet sent by
As we all know, to obtain a high network duration, you need to use a master router and a backup router with a hot fault recovery function and different network paths. But this is not enough. Routers themselves, especially those on insecure WAN edges, should be equipped with internal redundant hardware components, such as switching matrices, line cards, power supplies, and Route Processor RP ). High-availability routers must also support fast software recovery technology.
