“N-Study” is a network technology explanation site that helps you to better understand how networks are connected, a fact that we now take for granted.
The content is mainly focused on Cisco, and is also useful for studying for certification exams such as Cisco CCNA/CCNP/CCIE.
We hope that it will be of interest to IT engineers and everyone else who uses networks on a daily basis to learn more about how networks are connected.
|How the OSPF works||OSPF (Open Shortest Path First) is the most commonly used routing protocol in enterprise networks. It is important to understand how it works in order to use OSPF effectively. This section explains how the OSPF works.|
|How the EIGRP works||EIGRP (Enhanced Interior Gateway Routing Protocol) is a Cisco proprietary routing protocol. When determining the optimal route, you can also determine the available backup routes. This gives you the advantage of being able to switch routes quickly in the event of a failure.|
|How the BGP works||BGP (Border Gateway Protocol) is a routing protocol mainly used by Internet Service Providers (ISPs) to provide Internet access services. A key feature of BGP is its ability to scale to handle vast amounts of Internet route information, allowing for flexible control over optimal route decisions.|
|Advanced IP routing||We will discuss more advanced IP routing technologies such as filtering route information to be advertised by routing protocols, adjusting metrics, and redistributing when using multiple routing protocols.
These advanced technologies allow you to create router/layer 3 switch routing tables the way you want them to be. It allows you to control the routes that IP packets are forwarded.
|Cisco Basic||Cisco networking device has a large share of the enterprise network. Many non-Cisco devices also have a Cisco-like command system. Learning the basics of working with Cisco device, such as the contents of Cisco’s device configuration files and the command system, is the foundation of networking.|
|How to Use GNS3||GNS3 is a free software that can emulate various devices including Cisco routers, etc. With GNS3, you can virtually configure and verify the operation of various systems on a PC. It’s also very useful for studying CCNA/CCNP/CCIE etc.|
