1. Connect PC Ethernet port and Cisco router Ethernet port by using:
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
·
or the subnet between next two routers
·
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)
