This video is the second part of the ninth episode of the Network part of the Linux system engineer training course. The main content is IP interconnection between Cisco switches and routers, configuration Backup recovery, and IOS Backup Recovery and upgrade of switches. At work, I found that many Linux O M personnel encounter bottlenecks due to lack of basic network knowledge, and it is still a common phenomenon thanks to the inapplicable education system in China ). From the perspective of

This video is the tenth video course for the Network part of the Linux system engineer training. The main content is the working principle, STP Spanning Tree Protocol, and basic configuration of Cisco switches. At work, I found that many Linux O M personnel encounter bottlenecks due to lack of basic network knowledge, and it is still a common phenomenon thanks to the inapplicable education system in China ).

receive the broadcast frame. Broadcast domains and conflicting domains are particularly confusing concepts. We can distinguish them as follows: all devices connected to the two hubs constitute a conflict domain and a broadcast domain; the devices connected to each port on a vswitch without VLAN division belong to different conflict domains (each exchange port constitutes a conflict domain), but belong to the same broadcast domain. Bridging The so-called "bridging" mainly refers to transparent b

And the n

This video is the first video course of some network-related training courses for Linux System Engineers. The main content is the IP routing principle and the RIP Protocol.

many people, a software developer does not understand Cisco, which is also a fact! The gap between software development and Cisco is really deep and deep in China. If you say that you are engaged in software development and program writing, when facing a ccnp, you will be faced with a lot of problems in the cloud, such as OSPF, route injection, BGP, and frame relay... when you say socket, the segment is wrong... you have been frustrated before...Why? Only because the network and software develo

The dynamic routing protocol is also an important part of the routing protocol. Many people may not know the detailed knowledge of RIP, OSPF, and VPN in the dynamic routing protocol, after reading this article, you must have gained a lot. I hope this article will teach you more things. We have already briefly introduced three types of Dynamic Routing Protocol algorithms: Distance Vector Algorithm, link state algorithm, and balanced hybrid algorithm. Let's take a look at the types of these algori

Linux is divided into several stages-general Linux technology-Linux technology and application information. The following is a detailed description. According to my current understanding of linux, several specific subjects are subdivided in each phase, hoping to dismember the entire system into a small piece of things to digest.
