Cisco Packet Tracer 7.3.0

Part 1: Initialize Devices and Set Up the Topology (Name: Student id:

)

Step 1: Initialize and reload the router and switch a. Add two PC, a 2960 switch and an 1841 router in Cisco Packet Tracer b. Initialize and reload the switch/router following instructions in Appendix A

Step 2: Cable the network as shown in the topology. a. Attach the devices as shown in the topology diagram

Step 3: Attach your screenshots

Part 2: Configure Devices and Verify Connectivity (Name:

Student id:

)

Step 1: Configure the PC interfaces. a. Configure the IP address, subnet mask, and default gateway settings on PC-A. b. Configure the IP address, subnet mask, and default gateway settings on PC-B. c.

Ping PC-B from a command prompt window on PC-A. Why were the pings not successful? There was no ip address assigned into router 1 (R1). 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. a. Console into the router and enable privileged EXEC mode. b. Enter into global configuration mode. c.

Assign a device name to the router.

d. Disable DNS lookup to prevent the router from attempting to translate incorrectly entered commands as though they were hostnames. e. Assign cisco as the privileged EXEC encrypted password. f.

Assign ciscoconpass as the console password, establish a timeout, enable login, and add the logging synchronous command. The logging synchronous command synchronizes debug and Cisco IOS software output and prevents these messages from interrupting your keyboard input.

g. Encrypt the clear text passwords. h. Create a banner that warns anyone accessing the device that unauthorized access is prohibited. i.

Configure an IP address and interface description. Activate both interfaces on the router.

j.

Save the running configuration to the startup configuration file.

Step 3: Verify network connectivity. a. Ping PC-B from a command prompt on PC-A. Note: It may be necessary to disable the PCs firewall. Were the pings successful and why? Yes, the router has been configured therefore the gateways to these have been routed so that PC-A can successfully ping PC-B.

Part 3: Show Router Information (Name: Student id:

)

In Part 3, you will use show commands to retrieve information from the router. (attach your screenshot)

Step 1: Display the routing table on the router. What do codes “C” mean? Connected How many route entries are coded with a C code in the routing table? 2

Step 2: Display interface information on the router. What is the operational status of the Fa0/0 and Fa0/1 interfaces? FastEthernet0/1 is up, line protocol is up What is the IP and MAC addresses of Fa0/0 and Fa0/1 interface? Fa0/0: IP: 192.168.5.1/24

MAC: 0060.70a5.8c01

Fa0/1: IP: 192.168.11.1/24 MAC: 0060.70a5.8c02

Step 3: Display a summary list of the interfaces on the router and switch. 1. If the Fa0/1 interface showed administratively down, what interface configuration command would you use to turn the interface up? R1(config-if)#no shutdown 2. What would happen if you had incorrectly configured interface Fa0/1 on the router with an IP address of 192.168.1.2? 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.

Part 4: Analyse Network Traffic Step 1: Retrieve PCs’ interface addresses. (attach your screenshot)

PC-A: IP: 192.168.11.5

MAC: 00E0.F747.9100

PC-B: IP: 192.168.5.9

MAC: 0003.E49B.1A68

Step 2: Answer the questions. a. For the ping request data sent from PC-A while PC-A ping PC-B, what the source IP and MAC addresses and destination IP and MAC addresses? Source IP: 192.168.11.5 Source MAC: : 0060.70a5.8c01 Dest

IP: 192.168.5.9 Dest

MAC: 0060.70a5.8c02

Does the Source MAC address match PC-A’s interface? No Which interface is the Destination MAC address? VLAN1

b. For the ping request data arrived at PC-B while PC-A ping PC-B, what the source IP and MAC addresses and destination IP and MAC addresses? Source IP: 192.168.5.9 Source MAC: 0060.708c.5046 Dest

IP: 192.168.11.5 Dest

Week12 Networking Hands-on Assessment Does the destination MAC address match PC-B’s interface? No Which interface is the source MAC address? VLAN1

Demonstration Questions: 1. which command do we use to retrieve the Mac address for the interfaces in the router? Show interface fa0/1

Name: Sid: 2. which command do we use to retrieve the Mac address for the interfaces on the switch? Show interface fa0/6

Name: Sid: 3. which command do we use to retrieve the ip address for the interfaces in the router?

Show ip route

Week12 Networking Hands-on Assessment Done some steps forgot to screenshot, here is a screenshot of pinging from A to B and B to A

Appendix A: Initializing and Reloading a Router and Switch

Step 1: Initialize and reload the router. a. Console into the router and enable privileged EXEC mode. Router> enable Router# b. Type the erase startup-config command to remove the startup configuration from NVRAM. Router# erase startup-config Erasing the nvram filesystem will remove all configuration files! Continue? [confirm] [OK] Erase of nvram: complete Router#

c.

Issue the reload command to remove an old configuration from memory. When prompted to Proceed with reload, press Enter to confirm the reload. (Pressing any other key aborts the reload.) Router# reload Proceed with reload? [confirm] *Nov 29 18:28:09.923: %SYS-5-RELOAD: Reload requested by console. Reload Reason: Reload Command.

Note: You may be prompted to save the running configuration prior to reloading the router. Type no and press Enter. System configuration has been modified. Save? [yes/no]: no

Week12 Networking Hands-on Assessment d. After the router reloads, you are prompted to enter the initial configuration dialog. Enter no and press Enter. Would you like to enter the initial configuration dialog? [yes/no]: no

e. You are prompted to terminate autoinstall. Type yes and then press Enter. Would you like to terminate autoinstall? [yes]: yes

Step 2: Initialize and reload the switch. a. Console into the switch and enter privileged EXEC mode. Switch> enable Switch# b. Use the show flash command to determine if any VLANs have been created on the switch. Switch# show flash c.

If the vlan.dat file was found in flash, then delete this file. Switch# delete vlan.dat Delete filename [vlan.dat]? Delete flash:/vlan.dat? [confirm] Switch#

d. Use the erase startup-config command to erase the startup configuration file from NVRAM. You are prompted to confirm removing the configuration file. Press Enter to confirm to erase this file. (Pressing any other key aborts the operation.) Switch# erase startup-config Erasing the nvram filesystem will remove all configuration files! Continue? [confirm] [OK] Erase of nvram: complete Switch#

e. Reload the switch to remove any old configuration information from memory. You are prompted to confirm reloading the switch. Press Enter to proceed with the reload. (Pressing any other key aborts the reload.) Switch# reload Proceed with reload? [confirm]

Note: You may be prompted to save the running configuration prior to reloading the switch. Type no and press Enter. System configuration has been modified. Save? [yes/no]: no
