Subnetting Tutorial & Reference

Router Configuration Checklist

  • Identify the interfaces to be used.
  • Identify the directly connected networks.
  • Determine the network address of each network.
  • Configure the IP address and subnet mask on only those interfaces to be used.
    • Double check you’re adding the correct IP address to the proper interface.
  • Enable the interface(s) : no shutdown
  • Add the routing protocol
    • Add only the network address of each “directly connected” network.

RIP Routing Protocol

Troubleshooting & Verifying Networks

Hands-on Lab-03: 

Configuring Router interfaces, and the RIP Routing Protocol

  • You’ll need a USB Flash drive with at least 200MB of free space to save your labs.
  • You must be in class this day, and submit a working simulation file, to receive full credit for completing this lab.
  • When saving, always increment the version number at the end of the filename every time you save. And, save often.
    • Starting Filename: CST3607 Lab-<##> YourLastName, YourFirstName v01
  • Download Lab-03 Assets zip from the Downloads page, containing:
    • Packet Tracer Template
    • Instructions (PDF)
    • Network Diagram (PDF)
    • The lab must be done in the current version of Cisco Packet Tracer
  • Note: Substitute the # within an IP address with the number assigned to you in class. Use all other octets/digits, as written.
  • After you’ve verified that all of your configurations are complete and accurate, and you’re able to ping from host A to B and from B to A, and the routing tables on both routers are correct, only then e-mail your completed simulation file and configuration text file to me for grading.
    • E-mail Subject: CST3607 Lab-03 YourLastName, YourFirstName
  • Note: Do not use “version 2” when configuring RIP
  • Important: A fully functional & accurate Lab-03 is required, as it is the starting point/baseline for future labs.

Document the configuration of each router in your lab

  • Save the output from diagnostic commands for each router
  • Create a new TXT file with the same filename as the simulation file you’re documenting.
    syntax: CST3607 Lab-<##> LastName, FirstName v<version #>.txt
  • At the top of the TXT file, type your CST3607 Lab-<##> <YourLastName>, <YourFirstname>
  • Paste the output from all routers into the one TXT file:
    1. Make sure all routers have unique names: e.g. hostname 2621-A, 2621-B, etc.
    2. Close and reopen the CLI, to clear its history.
    3. enable
    4. terminal length 0
    5. show ip interface brief
    6. show ip route
    7. show ip protocol
    8. show ip ospf neighbor {If using OSPF}
    9. show controllers s0/0 or s0/1 {If the router has a DCE interface}
    10. show ip dhcp binding {If the router is configured as a DHCP server}
    11. show run {Make sure to press the space bar to complete the listing if the CLI says “–More–”}
    12. Select all the text in the CLI, then copy.
    13. Switch to your TXT file, and paste.
    14. Save the TXT file.
    15. Repeat for each router in the lab.
  • Send the TXT file with all router configurations to me: Subject: CST3607 Lab-<##> <YourLastName>, <YourFirstname>
