Comments: This article describes the basic configurations of Cisco routers. The configuration process of Cisco routers is still complicated, and there are many factors to consider, especially in terms of security. In fact, there is no need to make the router think so complicated. In fact, the router is a computer with multiple ports, but it plays a different role in the network than the general PC. How can

CISCO has become a leader in the switch industry, so I have studied the comprehensive performance of CISCO switch 2950. I would like to share it with you here, hoping it will be useful to you. Fixed installation of wire speed fast Ethernet desktop CISCO switch 2950, can provide excellent performance and functionality for LAN. These independent, 10/100 adaptive
The experiences of successful users are undoubtedly very important to us, because they not only know the road to success, but also know the road to failure, these experiences are of great reference value to latecomers. Friends who have already passed ccna are very willing to share their experiences with you.
Some netizens collected some experiences and sorted them out, hoping they could help those who are preparing for the ccna exam.

At present, Cisco routers have a very high market demand. Here we mainly introduce the use of OSPF to solve the defects of the RIP route information protocol, including the OSPF Authentication Method. OSPF is also an open version of The Link Status Protocol.
In practice, OSPF is often used in some large and hybrid networks. In the previous article, I talked about the defects of the RIP Protocol. The reason why network experts develop the OSPF protocol
How to configure IP address and MAC address on a Cisco switch binding Content Summary: at present, many of the company's internal network, has adopted the MAC address and IP address binding technology. Here we will introduce the configuration of IP address and MAC address bindings for Cisco switches. Description: at present, many of the company's internal network, has adopted the MAC address and IP
We know that there are four types of firewalls: integrated firewall capabilities of the router, integrated firewall capabilities of the proxy server, a dedicated software firewall and dedicated hardware and software combined with the firewall. Cisco's firewall solution includes the first and fourth of the four types: the integrated firewall feature router and the dedicated hardware and software combination firewall.
