How to Configure RIP on Juniper in GNS3 1.1 In this article i will show you how to run the RIP ( Routing Information Protocol ) among juniper routers. when you configure the RIP on junos by default it will enable RIP v2 & this is one of the difference from Cisco where you need to configure version2 manually. I have simulated this lab on gns3 which is one famous network simulator. For juniper simulation i have used junos olive  only for study purpose  and  junos olive  is not suitable for any type of commercial use.  Gns3 Labs detail are as mention below but you can use  any versions of these software. Gns3 version= Gns3 1.1 Junos version=    JunOS Olive 12.1 VM image VM VirtualBox version=    4.2.4  If you want learn more about the configuration of junos in gns3 you can visit how to configure junos on gns3 . Lab Requirements: There are three Junos routers in given topology which are connected with each other and already configured with correct IP address

Wide Area Networks Wide Area Networks can be seen as connection pipes that interconnect Local Area Networks. Usually WANs in contrast to LANs are not owned by the public; they are owned by service providers and their functionality-infrastructure is leased in order for LANs to be able to extend their expandability and make use of distant-remote services. A number of different WAN connection types exist today. Choosing the right WAN connection type is up to you, but the information in this article will make your decision process much easier. WAN Connection Types Leased Line: This is considered to be a dedicated point-to-point connection type where a permanent communication path exists between a Customer Premise Equipment (CPE) on one site and a CPE at the remote site communicating through a Data Communicating Equipment (DCE) within the providers’ site. Synchronous serial lines are used for this connection and the most frequent protocols observed in these lines are HD

The Transmission Control Protocol/Internet Protocol (TCP/IP) suite was created by the U.S. Department of Defense (DoD) to ensure that communications could survive any conditions and that data integrity wouldn’t be compromised under malicious attacks. The Open Systems Interconnection Basic Reference Model (OSI Model) is an abstract description for network protocol design, developed as an effort to standardize networking. In this article, I will present the differences between the DoD and the OSI models and then provide details about the DoD’s version of TCP/IP. I will also describe the protocols used at the various layers of the DoD model and provide you with the details of TCP and UDP protocols. Throughout this article you will find useful information concerning the protocol suite of the century: TCP/IP. So if you’re preparing for your CCENT or CCNA exams, or if you’re just interested in networking, this is one article you don’t want to miss! Fasten your s
