"making learning fun again"

1.      Connect PC Ethernet port and Cisco router Ethernet port  by using:

• Cross-over UTP cable  (cable with pin 1 connected to pin 6 and pin 2 connected to pin 6, both on RJ45 connector) or by using:

• HUB and two straight UTP cables.

2.      Power on the router and look at the massages appearing on the screen, while the router is booting

Part 1

BASIC COMMANDS

Using the commands on the router:

• show version

• show ip interface brief (or show interface)

Answer the following questions:

1. Router name:
2. Router type:
3. IOS version:
4. Memory amount:
5. Flash ROM amount:
6. Number and types of interfaces:

Part 2
              

Part 3

Set up a new  IP address, mask and Default Gateway  on each  WG PC

• Each WG should decide which IP addresses will be used (from each subnet) for PC to router connection and for router to router connection . 

• Start -> Settings -> Control panel -> Network -> TCP/IP Ethernet… -> Properties -> IP address and Gateway

Part 4

Displaying the configurations

      Enter privilege mode (enable)

     Display the configuration saved in NVRAM (show config)

     Display the running configuration (show running-config)

Setting and changing the configuration

      Enter the configuration mode (conf term)

     Change the router name (hostname)

     Exit the privilege mode (CTRL-Z), you are back in Privileged mode!

     Save the configuration (copy running-config startup-config)

Setting the passwords (REMEMBER YOUR PASSWORD)

      Enter the configuration mode (conf term)

     Specify virtual terminal lines you would like to configure (line vty 0 4)

     Request login authentication (login)

     Set a password for the exec mode (password my_password)

     Set a password for the privileged (enable secret my_password)

     Exit the privilege mode (CTRL-Z), you are back in Privileged mode!

Configuring the interface

     Enter the configuration mode (conf term)

     Select first ethernet interface 
     (interface ethernet - you got all the types of interfaces from part 1 task – for example Interface Ethernet0/0)

     Select the ip address and subnet mask (ip address your_IP_address  mask )

     Enable the interface (no shut)

     Exit the privilege mode (CTRL-Z), you are back in Privileged mode!

Checking router status and IP connectivity

      Check host connectivity (ping connected_PC_ip_address)

     Check host reachability (trace connected_PC_ip_address)

     Check status of an interface (show interface eth?)

     Display debug information (debug ip icmp)

     Disable debug information (undebug all)

Part 5

 Establishing router to router connectivity:

 Configuring the Serial interface:

  Enter the configuration mode (conf term)

     Select first Serial interface 
    (interface Serial - you got all the types of interfaces from part 1 task – for example Interface Serial0)

     Select the ip address and subnet mask (ip address your_IP_address  mask )

      Find out which Serial interface got connected DCE and which DTE CISCO cable

·        DTE (Data Terminal Equipment – MALE conector)

·        DCE (Data Communication Equipment – FEMALE connector)

      On Serial Interface with DCE cable enable line CLOCK by entering the command:

·        clock rate 1000000

      Enable the interface (no shut)

     Exit the privilege mode (CTRL-Z), you are back in Privileged mode!

  Connect DTE and DCE cable

  Checking router status and IP connectivity

      Check neighbor router connectivity (ping connected_router_ip_address)

     Check status of an interface (show interface serial?)

 Provide routers  with info where other (not directly connected) subnets  are by configuring static routes on each router:

 The command is:

 ip route <subnet> <subnet_mask> <next_hop_IP_address>

 ·        <subnet> is the subnet used for router-to-PC connection on the neighbor router

or the subnet between next two routers

·        <next_hop_IP_address> is IP address of  serial interface on the neighbor router

 Check  connectivity  (ping) from your PC to all other PC’s in your WG

·        open DOS window  (Start -> Programs -> DOS)

·        ping host_ip_address

 Check  reachibility (traceroute) from your PC to all other PS’s in your WG

·        open DOS window (Start -> Programs -> DOS)

·        tracert host_ip_address

Part 6  (optional)

 Connect your network to other WG network (by Ethernet or Serial connection):

·        decide which subnet will be used for interconnection

·        configure static routes to other subnets

·        Check  connectivity  (ping) from your PC to all other PC’s (in others WG)

·        Check  reachibility (traceroute) from your PC to all other PS’s (in others WG)
