Topology

Task 1: IP addressing Step 1. Consider the network requirements:

The 192.168.x.0/24 network must be subnetted to provide addresses for the three LANs. Each LAN requires 60 addresses. The subnet-mask /30 must be used for the serial connections between the three routers. The loopback address representing the link between the HQ router and the ISP will use the

200.200.200.200/32 network. Step 2. List the subnets used in the network in above topology. Subnet 1: 192.168.83.0/26 Subnet 2: 192.168.83.64/26 Subnet 3: 192.168.83.128/26 Subnet 4: 192.168.83.192/30 Subnet 5: 192.168.83.196/30 Subnet 6: 192.168.83.200/30

Task 2: Perform Basic Router Configurations. Perform basic configuration of the R1, R2 and R3 routers according to the following guidelines:

1. Configure the router hostname. 2. Disable DNS lookup. 3. Configure an EXEC mode password. 4. Configure a password for console connections.

Task 2: Configure and Activate Serial and Ethernet Addresses. Step 1. Configure interfaces of R1, R2, and R3. Configure the interfaces on the routers with the IP addresses from the addressing table. Step 2. Verify IP addressing and interfaces. Output of show ip interface brief command:

Step 3. Configure Ethernet interfaces of PC1, PC2, and PC3. Configure the Ethernet interfaces of PC1, and PC2 with the IP addresses and default gateways and test the PC configuration by pinging the default gateway.

Task 3: Configure RIP. Step 1. Enable RIP routing on three router. Show your RIP routing configuration?
