routing protocols

The routing information protocol, that is, the RIP Protocol. This protocol is one of the earliest in the routing protocol family. It plays a fundamental role in the development of some subsequent protocols. So let's compare several protocols. The Routing Information Protocol

(usually a user process, used to exchange route information with other routers through the routing protocol), and ICMP redirect messages change the route table. there is also an ICMP route discovery message, which can be used to update the default route entry through the solicited message of the machine that is started with advertisement and the new boot. this route discovery function is usually implemented by a user daemon. 5. the widely used IGP in

Many people may not have a special understanding of Static Routing and dynamic routing protocols. Here we mainly introduce the RIP and OSPF routing protocols. Static Routing is a fixed route table configured on the router. The sta

network topology changes. Dynamic Routing is suitable for networks with large networks and complex network topologies. Of course, various dynamic routing protocols occupy network bandwidth and CPU resources to varying degrees. Static Routing and dynamic routing have their o

IP route selection protocols can be divided into classless routing and classless routing. Route Selection Updates sent by the classless Routing Protocol do not contain subnet mask information, such as r12001; Route Selection Updates sent by the classless routing protocol inc

In practical applications routers are often connected to many different networks, to achieve communication between multiple networks, routing protocols are configured on routers, and in some large network topologies, there are situations where multiple routing protocols are common, and new technologies are used to---ro

This article describes the basic working principles of routers in TCP/IP networks and introduces several functions of IP routers, the static and dynamic routing protocols, as well as the concepts of the internal gateway protocol and the external gateway protocol are given, at the same time, the most common RIP, OSPF, BGP and BGP-4 routing

Before we talk about routing protocols, let's look at the structure of the routers:A router is a dedicated computer with multiple input ports and multiple output ports whose task is to forward groupings.The core of the routing part is the routing processor, which can construct a way out of the table according to the se

infrastructure or central device. In this system, all nodes can be moved randomly, and can maintain contact with other nodes, that is, each mobile node acts as both a router and a terminal at the same time. When two user terminals cannot communicate directly, communication is usually achieved by means of the routing function of other nodes ｡ The routing protocol is the basis for communication between mobil

The use of routing protocols plays an incomparable important role in network operation. We know that it is divided into many small types. Today, we will introduce the dynamic routing protocol. Dynamic Routing Protocol is the main method used by routers in network layer forwarding groups. The network is a very complex s

With the development of the Internet in China, the connection between ISP service providers and Internet is also changing. On a network connection, from a single connection to the Internet via multiple telecommunications companies, in terms of routing protocols used, from the use of static routing protocols to the use

When it comes to routing, users generally understand its role. However, as IT workers, IT is not enough to simply understand its role. We also need to understand the routing protocol and its classification. Now let's take a detailed summary of the classification of this routing protocol. First, let's take a look at its basic content. Classification of

Route information protocol (RIP) The routing information protocol was originally designed for Xerox PUPPARC universal protocol. In 1981, the Xerox network system protocol was collectively referred to as "GWINFO" and defined as RFC 1988 in 1058 ". The routing information protocol is easy to configure and works very well in small networks. However, in large networks, the
