TLEN5370 - Lab 0
Lab 0 - no deliverable (pass/fail graded based on completion)
Objective - Familiarize yourself with lab procedures and equipment
- Plan your network
- Build your network
- Router interface configurations and show commands
- Static routing
- Saving and restoring configurations
- Cleanup
Useful Cisco Commands
- ? - shows all possible commands
- enable - enter enabled mode
- write erase - erases the configuration
- reload - reboots the router
- show ip interface brief - shows all interfaces
- show running-config - show the configuration
- show interface (name)(number) - show the interface
- write mem - writes the configuration
- ping x.x.x.x - pings the indicated IP address
- configure terminal - enter configuration mode
Objective 1 - Sit down with your group and plan your network
- Build a network topology of your choice with the following constraints:
- Use four or more routers
- Use at least two ethernet links
- Use at least two serial links
- Make sure at least one router does not directly connect to one other router
- Connect your workstation into the network via ethernet so you can telnet to routers
- Use 10/8 as your address space
Objective 2 - Build your network
- Determine the routers you will use, the interfaces and the cables. Connect them.
Objective 3 - Configure your network
- Login to the workstation.
- Use the workstations console cable via patch panels to access routers and set intial configurations.
- Start by erasing the old config "wr erase" followed by "reload" Don't use the autoconfig builder when it reboots.
- A few config commands that might be useful at the start are:
- enable password (password) - this will set the password
- ip subnet-zero - this allows you to use the 1st and last subnets...don't ask...its a remnant of pre-CIDR days
- ip classless - this allows CIDR...for some reason it is off by default
- line vty 0 4 followed by password (password) - this will allow you to telnet in from your workstation
- hostname (routername) where routername is the name you give the router (something systematic might be useful especially when using m
ultiple routers) - this sets the text of the prompt
- You will lose points on future labs if you ask a question that is resolved by any of the above commands.
- From there build the interface configs.
- Once initial config is created use telnet to access the routers. (you might need to change IP of your workstation)
- Create the base config and verify you can ping between adjacent routers.
- Run some show commands to verify all is working correctly
Objective 4 - Configure some static routes and loopbacks
- Are your two non-touching routers able to reach one another?
- Use static routes to solve this problem.
- Verify all routers can reach all other routers
- Add a loopback on each router
- User static routes to make the loopbacks reachable from all other routers
Objective 5 - Saving, restoring, and documenting
- Determine a process for saving and then restoring configs. Remember most of the labs are multi-day and you will have to resume where you left off the next class.
- Also learn to carefully document all of your physical connections so you can recable your network quickly at the start of class.
Objective 6 - Cleanup
- Ever seen Jose mad? I'd recommend you do the following:
- Coil all cables and return to bins
- "wr erase" "reload" all routers
- Clean up your workstation area
