In this project we have three sites and they are connected together by a frame-relay environment and also we want to run EIGRP on our routers. After configuration, each client should be able to ping others. Our clients configuration are as follows: {C1} IP Address: 192.168.1.2/30 {C2} IP Address: 192.168.2.2/30 {C3} IP Address: 192.168.3.2/30 In this step we’ll configure a router as a frame relay switch: {Interface Serial 1/0} FR(config)#frame-relay switching FR(config)#int s1/0 FR(config-if)#no ip add FR(config-if)#no shut FR(config-if)#encapsulation frame-relay FR(config-if)#clock rate 64000 FR(config-if)#frame-relay intf-type dce FR(config-if)#frame-relay route 102 interface s1/1 201 FR(config-if)#frame-relay route 103 interface s1/2 301   {Interface Serial 1/1} FR(config)#int...

In computer networking, network address translation (NAT) is the process of modifying IP address information in IP packet headers while in transit across a traffic routing device. In this case we want to make an internal network that our clients can communicate with outside of our network such as an ISP.   Because we have just one IP, we must use dynamic NAT and also PAT. In PAT bandwidth shares between clients. Our internal network contains the below devices: One router. One switch. Two clients. And on other hand, ISP network have the below devices: One router. One client. ISPClient is like a web server, ftp server or any devices...

Frame Relay is a standardized wide area network technology that specifies the physical and logical link layers of digital telecommunications channels using a packet switching methodology. Originally designed for transport across Integrated Services Digital Network (ISDN) infrastructure, it may be used today in the context of many other network interfaces. In this project we will simulate a frame-relay switch by a router.We will use hub-and-spoke standard for connect sites together. We need to the below devices:   One router as a frame-relay switch. Three routers for our sites. Three clients for testing connectivity (You can use loop-back). Our network is like the below figure: We start with our frame-relay switch, for...

A log, maybe this term means for you to trashy files, unless information and …, maybe you’re right but sometimes a line even a word of these, can help you to resolve your problem, so I think logs are necessarily items for troubleshooting! In this project, we have 3 clients in a simple network and we want to control incoming and outgoing traffic and also send logs to a syslog server. I’ll use TFTPD32 as a syslog server, it’s very simple and suitable for small projects and for simulating my network I’ll use GNS3. Our goals are as follows: Run RIP protocol. Control ICMP protocol...

  Overview of Network Packet Tracer File We have two sites in a city or in two different cities, we need connect them by a fast, secure and low cost solution, Frame Relay is most common solution for it. Our goals in this project are as follows: Working with WAN emulation object. Configure serial ports for connect to a WAN emulation. Set Frame Relay as encapsulation protocol. Send and receive RIP packets over Frame Relay. [quotes_and_tips]

  Overview of Network   Packet Tracer File In this project we need to configure RIP routing in our corporate network and also we need to connect our network to the Internet. We have three sites Tehran, Shiraz and Isfahan. Tehran site is default gateway for our network. Other sites should be connected to Tehran for send or receive data to Internet. We set a static route between Tehran and ISP for connect to Internet. Our goals are as follows: Configure RIP protocol. Comparison RIPv1 and RIPv2 Set a “Gateway of last resort” for our network.

Packet Tracer File We have three routers that two of them connected directly by Serial port, goals in this project are as follows: Use classless IP address for each segment. Add static routes to each router. Configure Serial ports on Router1 and Router2. Test connectivity by Ping tool from each client in each segment. [quotes_and_tips]

Packet Tracer File   In this case we have two Cisco routers (2811) and two Cisco switches (2960) and also two PCs that each of them connected to one segment with different IP addresses.   We have one static route on each router: Router0: 192.168.2.0/30 via 192.168.3.1 Router1: 192.168.1.0/30 via 192.168.3.2 [quotes_and_tips]

Some times we need use a physical drive in our virtual machine, for it first we must login to our ESXi 5 server by a network protocol such as SSH or Telnet, after logon: You must check name of your device in this path: /dev/disks     for example my device name is:t10.ATA_____ST3500418AS_________________________________________9VMQSWK On previous path you must run this command: vmkfstools -z /vmfs/devices/disks/”Your device name” “VMDK file address” After run command, a VMDK file is made under the above path, you can add this file as a new hard disk drive to your virtual machine.
