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
