TopologyAddressing Table
Blank Line – no additional information ObjectivesPart 1: Set Up the Topology Part 2: Configure Devices and Verify Connectivity Part 3: Display Device Information Background / ScenarioThis is a comprehensive activity to review the IOS commands you have learned. In this Packet Tracer Physical Mode (PTPM) activity, you will cable the equipment as shown in the topology diagram. You will then configure the devices to match the addressing table. After the configurations have been saved, you will verify your configurations by testing for network connectivity. After the devices have been configured and network connectivity has been verified, you will use IOS commands to retrieve information from the devices to answer questions about your network equipment. This activity provides minimal assistance with the commands necessary to configure the router. Test your knowledge by trying to configure the devices without referring to the course content or the previous activities. Instructions
In this part, you will set up the network topology and configure basic settings, such as the interface IP addresses, device access, and passwords. Refer to the Topology and Addressing Table at the beginning of this activity for device names and address information. Step 1:Assign static IP information to the PC interfaces.
Question:Why were the pings not successful? Type your answers here. The router interfaces (default gateways) have not been configured yet so Layer 3 traffic is not being routed between subnets. Step 2:Configure the router.

Note: If pings are not successful, the Windows Firewall may need to be turned off. Question:Were the pings successful? Explain. Type your answers here. Yes. The router is routing traffic across the two subnets. The default settings for the 2960 switch will automatically turn up the interfaces that are connected to devices. Step 3:Configure the switch.In this step, you will configure the hostname, the VLAN 1 interface, and its default gateway. Open configuration window
Switch> enable
Switch# config terminal
Switch(config)# hostname S1
S1(config)# interface vlan 1 S1(config-if)# ip address 192.168.1.2 255.255.255.0 S1(config-if)# no shutdown S1(config-if)# exit

Step 4:Verify connectivity end-to-end connectivity.
All the pings should be successful. Close configuration window Part 3:Display Device InformationIn Part 3, you will use show commands to retrieve interface and routing information from the router and switch. Step 1:Display the routing table on the router.

Step 3:Display a summary list of the interfaces on the router and switch.There are several commands that can be used to verify an interface configuration. One of the most useful is the show ip interface brief command. The command output displays a summary list of the interfaces on the device and provides immediate feedback about the status of each interface.

Type your answers here. R1(config-if)# no shutdown
Type your answers here. PC-A would not be able to ping PC-B. This is because PC-B is on a different network than PC-A, which requires the default-gateway router to route these packets. PC-A is configured to use the IP address of 192.168.1.1 for the default-gateway router, but this address is not assigned to any device on the LAN. Any packets that need to be sent to the default-gateway for routing will never reach their destination. |
