TROUBLESHOOTING A SMALL NETWORK

        In this scenario, you will design and configure a small network and verify connectivity across multiple network devices. This requires creating and assigning two subnetwork blocks, connecting hosts and network devices, and configuring host computers and one Cisco router for basic network connectivity. Switch 1 has a default configuration and does not require additional configuration.

      Use COPPER CROSS-OVER between Host 1 and Router Fa0/0 while COPPER STRAIGHT-THROUGH between Switch1 and Host 2 same cable type from Switch1 and Host2.

      After cabling the network devices, verify the connections.

The given IP address block of 192.168.30.0/27, design an IP addressing scheme that satisfies the number of hosts. The subnet A requires 7 host while the subnet B needs 17 hosts.

      The host computers will use the first IP address in the subnet. The network router will use the last IP address in the subnet.

Configure the Static IP address, subnet mask, and gateway for each host computer. After configuring each host computer, display and verify the host network settings with the ipconfig/all command.

Configure the first host. The IP address is 192.168.30.1 with its subnet mask 255.255.255.248 and default mask is 192.168.30.6. The Subnet A needs 7 hosts so the number of bits in the subnet is 3 its maximum number of usable subnets including the 0 is 8 while the number of usable hosts per subnet is 6. And the IP subnetwork address would be 192.168.30.0.

      After that configure the second host. The IP address 192.168.30.1 with its subnet mask 255.255.255.240 using the prefix /29 and its default gateway 192.168.30.14. The Subnet B needs 17 hosts and the number of bits in the subnet is 4 and the maximum number of usable subnets including the 0 subnet is 16 and the number of usable hosts per subnet is 14. The IP subnetwork address is 192.168.31.0.

Now let us configure the Router 1 with the use of CLI ( IOS Command Line Interface).

Set the router name to Router1 and then set the Encrypted privileged exec password class  the console access password cisco and the telnet access password is cisco.

And then configure the port interface fa0/0, its ip address is 192.168.30.6 255.255.255.248 then PRESS ENTER and type no shutdown then type END.

Then configure the port interface fa0/1, its ip address is 192.168.31.14 with its subnet mask 255.255.255.240 then PRESS ENTER and type NO SHUTDOWN then type END.

Verify the network connectivity using the PING command through COMMAND PROMPT.
