Dynamic and robust routing is extremely important for Internet networks. Therefore, any network engineer who is first involved in this field must not only understand the concept of routing, but also be able to control it in a real environment. However, the products provided by high-end network equipment suppliers such as Cisco in the routing field are all over the world. This means that most people can only learn routes in school or laboratory environments, it also has to be plagued by practical

Previous: static Router DynamicRouting ProtocolFeatures 1) the dynamic routing protocol can automatically update its route table and send updated messages to other dynamic routing protocols it knows. 2) the purpose is to manage the work of the network administrator. 3) There must be a routing protocol suchRIPOrOSPF.

I will not talk about the software framework. I have explained it in detail on the official zebra website. To put it simply, Zebra serves as a daemon to maintain Linux routing information, and rip is used by other modules, BGP and the daemon update and obtain route inform

LVS: Linux Virtual Server Layer-4 Switching (Routing): forwards request packets to a server in the backend host Cluster Based on the target IP address and target PORT (based on Scheduling Algorithm ); Load Balancing at the application layer cannot be achieved Lvs (also known as ipvs) is implemented based on the firewall netfilter in the kernel. 2. lvs cluster terminology: Vs: Virtual Server

RIP (Routing Information Protocols) Routing Information Protocol OSPF (Open Shortest Path First) Open Path First (Enhanced Interior Gateway Routing Protocol) Enhanced Internal Gateway Routing Protocol Static Routing: static Routing is only applicable to small networks or small to medium-sized networks with only a small scale. Manual Input and manual management are required. Management overhead is a huge burden for dynamic routing. Advantages: Excellen

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. L

I. Lab Objectives Master the configuration of Integrated routes; View the routes generated by route redistribution; Familiar with Wan cable connection methods; Ii. Lab background Assume that a company connects to the egress router R1 through a layer-3 switch, and router R1 is connected to another router R2. Layer 3 and R1 run the r12002 routing protocol, while R1 and R2 run the OSPF routing protocol. Now, we need to make proper configuration to implement communication between the company's

0, R2 and R3 belong to the ospf region 1, R3 and R4 belong to the ospf Region 2, and R2 and R5 adopt the rip Protocol; 2. use virtual connection to connect area2 and area0 through area1. 3. route table reduction is achieved by setting a remote route and a full remote route. 4. achieve network-wide interconnection. Note: device models: R1, R2, R3: R2661; R4, R5: S35265E. Experiment configuration: for example, the ip address planned in the experiment t

, IPX, and appletalk. IP is the cornerstone of Internet. In the TCP/IP protocol system, other third-level auxiliary protocols include ARP (Address Resolution), RARP (Reverse Address Resolution), and ICMP (internet packet control) and IGMP (Group Management Protocol. Because all network interconnection devices have the path selection function, we often discuss the rip, OSPF, and other routing protocols at this layer. Exchange When talking about exchang

reporting and handling error situations. The ICMP protocol has multiple functions. In addition to sending route error messages to data senders, it can also detect the accessibility of network nodes (using icmpecho and reply information ), improve routing efficiency (icmpredirect information is used), and remind the sender that the packet exceeds the survival time (icmptimeexceeded information is used. In short, the ICMP protocol is an essential part of the entire IP network, especially for thos

The request message and the response message must be forwarded by the Director, the director is easy to become

1, the following conditions as long as there is an unsatisfied, you need to use a dynamic routing protocol: 1) network size is small, 2) only one connection point for connecting to other networks, 3) No redundant routers (typically used as backup)2, the so-called dynamic routing is each router and its own adjacent routers to exchange the information of their connected networks, so that their own routing table is always up-to-date, and different communication update mode, called different dynamic

OSPF Protocol principle 1. ospf (Open Shortest Path First) is an Internal Gateway Protocol (IGP) used for decision-making routing in a single autonomous system (. Ospf runs directly on the IP protocol and uses protocol number 89. ospf is a link-State routing protocol, which is generally used in the same routing domain. A routing domain is an autonomous system. It refers to a group of networks that exchange route information through a unified routing policy or routing protocol. In this AS, all os
