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)
