Background Subnetting is an important technique to conserve the IPs. Classful Subnetting allow you to divide a full range of a network (e.g. 192.168.0.0/24) to subnetworks equally. This still does not conserve IPs fully as some companies might need smaller networks in some branches/ departments than other their branches/departments. Classless Subnetting uses Variable Length Subnet Mask (VLSM) technique that allow you to divide the network to different sizes compared to Classful Subnetting. In this lab, you will be guided to compute Classless Subnetting to networks from a given requirement. Then, you will use the computed Subnets in the topology shown in Figure 1. In addition, Routing Information Protocol (RIP) is a commonly used routing protocol in small to medium TCP/IP networks. It is a stable protocol that uses a distance-vector algorithm to calculate routes. In this lab, you will use Packet Tracer to configure the small topology shown in figure 1 using RIP protocol. You will be guided to record down all the IPS and RIP commands for this exercise.
Build the below network topology (10 Marks): Q1. Classless Subnetting (20 Marks): Given (192.168.0.0/21), use the VLSM Subnetting technique to find suitable Subnets for the topology shown in figure 1. Use table 1 to generate the Subnetting table. Assume: 1000 Hosts for Muharraq Network, 200 Hosts for Hamad Town Network, 100 Hosts for Budaya Network and 16 hosts for Saar Network.

Q2. PCs configuration (5 Marks): 1. Connect the topology shown in figure 1 using Packet Tracer. 2. Use table 1 to assign IPs in table 3 to all PCs including the Default Gateway. IP address Device PC 1 PC 2 PC 3 PC 4 PC 5 PC 6 PC7 Web Server Device R1 Q3. Routers configuration (5 Marks): 1. Use table 1 and table 2 to assign IPS to Routers' interfaces. 2. Make sure you enable the interface (no shutdown) R1 2222 R2 R2 R3 R3 R4 222 22 R4 RO RO Subnet Mask Table 3 IP addressing for PCs using Classless Subnetting. 3 Interface $0/0/0 GO/1 50/0/0 GO/1 50/0/1 G0/1 50/0/1 GO/1 $0/0/0 50/0/1 50/1/0 50/1/1 Default Gateway IP address Subnet Mask Table 4 IP addressing for Routers using Classless Subnetting.
Q4. Testing (2 Marks): 1. Test the connections using PING between the PCs in one LAN and their Default Gateway 2. Test the connections using PING across the LAN networks. Is it successful? Q5. Use RIP protocol to bridge the LAN networks (15 Marks): 1. Apply RIPv2 in all routers. Use table 4 to show all the codes you plan to use. 2. Once all codes are applied in the routers, use "show ip route to make sure all networks are known to the Routers. Resolve any issue if not all networks are known.
