Activity 2: IP and routing This is a group activity. Therefore, you need to form a group of four (4)~ five (5) people. At your table (or in MS team chat) discuss the following questions with your group members. Remember to take notes as they will help you prepare your task submissions and complete other activities. 1. Assume you are sending a present to a friend in another country. Can you list the various places and steps that your parcel would go in the postal system before it reaches your friend? Ans: 1. Package transported from home to the post office 2. Then post office processed the package and get it ready for shipment 3. Packet then transported from post office to distribution centre 4. Then it transported to the airport 5. Package is loaded to the plane 6. Then plane goes to the destination address 7. At destination country, package is unloaded and sent to distribution centre 8. Then the distribution centre sends it to the destination address and assigns delivery 9. Delivery driver drops transports package to destination address 2. How this analogous to a situation where you want to send a message to a friend in another country over the computer networks? Ans: When sending a message to a friend on a different network, the message is packaged up and sent through different protocols. At each stage the protocols read the information and route the message to the appropriate stage until the message is delivered. 3. Assume we need to build the following network with two LANs (LAN1 and LAN2). Each group member has a role to play. One group member can be the router and four other group members could be PCs (PC1 and PC2 belong to LAN1 and PC3 and PC4 belong to LAN2). Each device needs to set their own network configuration. The Router needs to set its interfaces/port and PCs need to set its IP address and gateways to be able to make a communication between two LANs. Discuss the configurations of your own device with your group members. Ans: PC1-10.1.1.2 PC2: 10.1.1.3 PC3:192.168.1.2 PC4: 192.168.1.3 SUBNET FOR ETHERNET 0/0: 255.255.255.0 SUBNET FOR ETHERNET 0/1: 255.255.255.0 DEFAULT GATEWAY FOR PC1 AND PC2: 10.1.1.1 DEFAULT GATEWAY FOR PC3 AND PC4: 192.168.1.1 4. Assume PC1 needs to send a packet to PC3, discuss the steps that the packet needs to go through to reach to PC3. LAN1 10.1.1.0/24 PCKS Switch 1 PC2 Router PC3 LAN2 192.168.1.0/24 Switch 2 PC4 Ans: PC-1 will calculate its subnet and see that PC-3 is out of the local network so it will send an ARP request to get the MAC address of the gateway. The router has received a packet on interface fa0/0 from pc-1 so it will first check DST-IP which is PC-3 and match this IP with a network-ID in its routing table. Router-3 has received the packet so now it will again do the same thing which router-1 did upon receiving packet from PC-1. PC-3 has received this packet so first it will compare Dst-Mac received in packet with its own Mac and if it matches then it will match Dst-IP from same packet to its own IP and if both things matches then it will accept the packet and process it towards application layer. Activity 3: Implementing what you learnt. 1. Implement the above-mentioned network in Cisco Packet Tracer. You need to determine the IP addresses of all PCs depending on the LAN that they belong to (you have done this in Activity 2). 2. Once all the devices are configured and connected properly, verify the connectivity using command prompt "ping" in one of the PCs (ex: if PC3's IP address is 192.168.1.5 then from PC1's command prompt we can type "ping 192.168.1.5" to verify the connection) C:\>PING 192.168.1.2 Pinging 192.168.1.2 with 32 bytes of data: Reply from 192.168.1.2: bytes=32 time <1ms TTL=127 Reply from 192.168.1.2: bytes-32 time-1ms TTL-127 Reply from 192.168.1.2: bytes=32 time-1ms TTL-127 Reply from 192.168.1.2: bytes=32 time <1ms TTL-127 Ping statistics for 192.168.1.2: Packets: Sent - 4, Received 4, Lost 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = Oms, Maximum = 1ms, Average = Oms C:\> 3. Use the simulation mode to verify the steps that you have discussed in Activity 2 Step 4.

Connecting more devices to the network you built in Activity 3. 1. PC1 in the above diagram now wants to send a message to another PC (PC5) with the IP address of 198.168.2.4. 2. Discuss how PC5 is connected to the current network. 3. Add PC5 and other devices (if necessary) to the network you built in Activity 2 and verify the connectivity using "Ping" in one of the PCs.
