routing protocols

main function is to exchange network accessibility information with other BGP systems. BGP is an external Gateway Routing Information Protocol that enables non-loop exchange of routing information between autonomous systems. Based on classless Inter-Domain Routing (CIDR), BGP has been developed to support aggregation and reduction of

may depend on the number of forwarding times between nodes, the current network running status, data transmission rate, and topology. To find the optimal path, Each router needs to communicate with each other through the routing protocol. The routing protocol is only used to collect data about the current status of the network and find the optimal transmission path. Based on the data, the router can creat

backbone network, people connected to it through the IPIP (IP Encapsulation IP) tunnel. The Unix program mrouted can understand the DVMRP and IGMP protocols, but the Internet Router cannot. Many customers who want to adopt Multicast technology are still asking their ISP why some protocols do not work. DVMRP refers to the distance vector multicast routing protoco

There are many small details about the routing protocol, which deserves our attention. There are also many categories that indicate the different functions of different routing protocols. Now we will talk about the routing information protocol. For more information about the specific functions and features of this prot

Many of you know about the dynamic routing protocol. It also includes vector routing protocol and link status routing protocol. I don't know whether you have mastered these two features. Now let's take a closer look. Dynamic Routing Dynamic Routing

Before we start, let's start by thinking about several questions. What is a route? What are OSPF and BGP? What are their purposes? What are their application scenarios? What are the advantages of the two routing protocols in OpenBSD compared with hardware routers such as Cisco/Huawei? How to Use OpenBSD to reduce network costs? 1. What is a route? Simply put, a route is like a sign at a crossroads, a

communicate between the two. The internet enables any autonomous (Non-core) gateway to send "accessible" information to other systems, at least to a core gateway. If there is a larger autonomous network, it is often assumed that there is a gateway to handle these accessible information. Like GGP, EGP uses a query process to let the gateway know its neighboring gateways and continuously exchange Routing and state information with its neighbors. EGP i

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

Metric ). In RIP, the number of hops from a router to a directly connected network is 0, and the number of hops from one router to another is 1. To limit the convergence time, RIP requires the metric value to be 0 ~ An integer between 15 and 16. The number of hops greater than or equal to 16 is defined as Infinity, that is, the destination network or host is inaccessible. AD = 120) To improve performance and prevent the generation of routing loops, R

This article mainly introduces the self-organizing network routing protocols used in the self-group network. This article gives some specific instructions on these protocols, I believe that reading this article will help you. The cluster head gateway switch routing (CGSR) protocol is designed based on the DSDV protocol

Analysis plan of RIP routing protocols V1 and V2 is as follows: R1 connects to the Internet through a port and uses loopback to simulate the IP address of the host carrying the router R1: lo 0: 10. 1.1.1/24 f0/0: 192.168.0.1 www.2cto.com R2: lo 0: 10. 1.2.1/24 f0/0: 192.168.0.2 configuration: R1 R1 (config) # int lo 0R1 (config-if) # ip add 10.1.1.1 255.255.255.0R1 (config-if) # int f0/0R1 (config-if) # ip

Managing network bandwidth is becoming more and more important. On a network with no other routers, it makes no sense to route the broadcast traffic that flows out of the network interface. This is very inefficient for your router resource usage. Let's take a look at how to better bandwidth control by using the Passive-interface command. To properly configure the routing protocol, the Passive-interface command must not be unknown. However, if you are

For various reasons, many networks adopt multi-route protocols. This phenomenon is usually caused by merger and acquisition activities, or temporary occurrence during the migration. Many vro hardware manufacturers may use a variety of proprietary protocols to connect with standard protocols. Some routers will run more than one protocol and inevitably receive the

It is very important to know about dynamic routing protocols. Here we mainly introduce how dynamic routing protocols save network bandwidth and manage network bandwidth. In a network without other routers, it is meaningless to route the Broadcast Communication outbound from the network interface. This is very inefficie

In a network structure, the functions supported by the routing protocols in various network forms are different, and the connotation protocols are also different. Now we will introduce some features of the wireless communication routing protocol. And the Routing Protocol in

The RIP Routing protocol (Routing Information Protocols) is the most widely used distance vector protocol. It was developed by Xerox in 1970s. At that time, RIP was part of the Xerox Network Service (Xerox Network Service) protocol cluster. The TCP/IP version of RIP is the license version of Xerox protocol. The biggest feature of RIP is that the implementation pr
