Comparison between dynamic routing protocol RIP and OSPF: Three criteria for dynamic routing (IGP): good routing, fast convergence and less link resources Dynamic routing protocolRoute selectionconvergenceOccupied resources RIPThe number of hops is used as the overhead value in routingThe convergence rate is based on the timerLess occupation ...

preface Recently, I was accidentally isolated, had a holiday to think about it, and decided to start in the handwritten sequence. This sequence had an idea when looking at the source code of Nacous and gateway, but it has not been implemented. Take advantage of isolation. Introduction to essential knowledge Serializable and Deserialize Ser ...

Example: Requirement: R1-R2-R3-R4-R5 runs RIPV2, R6-R7 runs RIPV1 1. Use reasonable addresses to plan the network and create loopback interfaces for each 2, R1 Create Loop 172.16.1.1/24 172.16.2.1/24 172.16.3.1/24 3, requiring R3 to access R1 loops using R2 4. Reduce the number of routing entries and increase routing delivery security 5 ...

Experimental content There are 15 experiments in this part, which need to be completed by Cisco packet tracker software. Preparation stage 1. Understand the concepts of VLSM, CIDR, RIP, OSPF, VLAN, STP, NAT and DHCP, so as to be able to plan and configure the network. 2, Understand the basic use of CPT Experimental content Connect two ...

Into modern communication Shannon Weaver model A linear and unidirectional framework is constructed to describe the information dissemination process of the generalized communication system. This mode includes six parts: source, transmitter, channel, noise, receiver and sink. Source and sink: source is the source of information; The destinat ...

1. Related concepts of network 1.1 network communication (1) Concept: data transmission between two devices is realized through network (2) Network communication: transfer data from one device to another through the network (3)java.net package provides a series of classes and interfaces for programmers to complete network communication 1. ...

Simulate BGP group attribute policy configuration instance using eNSP Problem elicitation As shown in the figure There are two user network segments in AS 300 When users in AS 100 access these two network segments It is hoped to realize traffic sharing on R2 and R3 When AS 200 accesses these two network segments It is hoped that traf ...
