GNS3 on Network

1. The layout of a network is from the data given from project 3. The aim of this is to assign the IP and MAC address for 3 hosts and add one host. The following are the step how the computer network works and the host pass data through switch –router –switch.

2. Each host has identified according to their IP address. This configuration is delivered by right-click the host icon and then choose console. Type IP [address] [netmask] [gateway]. The data is given and assigned to each host. The netmask is 255.255.255.0.

3. Each router has connected. Router Engineer, Montebello, and CEBIS are routers which its connect each other so the configuration on each ethernet has defined actually, to access IP address on each router connected, are numbered 3 like Engineer router to Montebello router and CEBIS router and to the switch.

4. The output is shown on a ping from PC2 to PC1. Actually, a ping has 4-6 times display passes through the network. Timeout not delivered or received data. The bytes there is the size of ping packet pass through the network. Packet means a mode of transmission which a message is in part make small and sent through a network on destination through route. The icmp_seq a fragmented request sent by router. TTL is the number of hop of packets how long takes these packets to a destination. It depends on number TTL.

5.Router IP Route and ARP
Engineering IP Route and ARP

Montebello IP Route and ARP

CEBIS IP Route and ARP

ARP or address resolution protocol is a protocol that representing IP address of hardware addresses of the remote and IP addresses set at the local endpoint. The router handles the IP connection to it, for example, PC1 is connected to Engineer Router so its show IP address of PC1 through Ethernet. However, IP route on the router can display the routes that network flows. Each terminal displays its IP address. This terminal can be kinds of ethernets, switches, and hubs.


6. PC1 its IP address is 10.1.1.1
PC2its IP addrees is 10.1.2.1
PC3 its IP address is 10.1.3.1
There is no arp on hosts.

7. PC1 MAC: 00:50:79:66:58:00
PC2 MAC: 00:50:79:66:58:01
PC3 MAC: 00:50:79:66:58:02
MAC address has been configured by type on console on host show ip.
8. There capture on other GNS3, the Wireshark can detect the map data from a network so that can be seen ff:

Each column has assigned as No. Time, source, destination, protocol, length, and info. It was captured on a network and this is a packet list to one packet that is in the capture file.Wireshark shows level of a protocol of high levels. The column No. is the number of the pockets and not change. Time is the timestamp. The source which packets are gathered from. A destination where the data or address where the packet is going to, Protocol, its name of protocol like TCP, or IP, length also included in each packet, the information is also given on info column.

9.
The new host is added on Montebello Router. The gateway of this host must same to the gateway to its network family on Montebella Router. The Ip configuration must different in level 10.1.2.x, the x range from 0 to 255 but its different to assigned at 10.1.2.1. same with the configuration on IP. Ping has been successfully configured.

10. OSI layers or as known as open system interconnection which defines as a model for management in a network that implements protocol on a computer has 7 layers. The transmission through this is a definition of encapsulation and decapsulation of data which received and transmitted thought OSI layers. levels of OSI arrangement are application presentation session transport network datalink physical.For encapsulation, there is a movement of data from OSI layers from Presentation to Physical. Data packets containing headers and data from upper layers are converted into data to be repacked at the next lower level in the lower layer header. The header is supplementary information placed at the beginning of the data block at the time of transmission. This supplemental data is used at the receiving side to extract data from the encapsulated data packet. Packaging this data in each layer is known as data encapsulation. The reverse process of encapsulation (or decapsulation) occurs when data is received at the destination computer. When the data passes from the Physical of the TCP / IP protocol stack (input transmission), each layer decompresses the corresponding header and delivers the packet to the network application using the information contained in the header exactly the data waited for on the Application layer.
