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:
Answer the following questions:
|
| Part 2  |
| Part 3 Set up a new IP address, mask and Default Gateway on each WG PC
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) |
