Objectives
Part 1: Display Router Information
Part 2: Configure Router Interfaces
Part 3: Verify the Configuration
Background
In this
activity, you will use various show
commands to display the current state of the router. You will then use the Addressing Table to configure router Ethernet interfaces.
Finally, you will use commands to verify and test your configurations.
Note: The routers in this activity are partially configured. Some of the
configurations are not covered in this course, but are provided to assist you
in using verification commands.
Part 1:
Display Router Information
Step 1:
Display interface information
on R1.
Note: Click a device and then click the CLI tab to access the command line directly. The console password
is cisco. The privileged EXEC
password is class.
a.
Which command displays the
statistics for all interfaces configured on a router? ____________________
b.
Which command displays the
information about the Serial 0/0/0 interface only? _____________________
c.
Enter the command to display
the statistics for the Serial 0/0/0 interface on R1 and answer the following
questions:
1)
What is the IP address
configured on R1? _______________________________________________
2)
What is the bandwidth on the
Serial 0/0/0 interface? ____________________
d.
Enter the command to display
the statistics for the GigabitEthernet 0/0 interface and answer the following
questions:
1)
What is the IP address on R1? ________________________________________________________
2)
What is the MAC address of the GigabitEthernet
0/0 interface? ______________________________
3)
What is the bandwidth on the GigabitEthernet
0/0 interface? ________________________________
Step 2:
Display a summary list of the
interfaces on R1.
a.
Which command displays a brief
summary of the current interfaces, statuses, and IP addresses assigned to them?
____________________________________________________________________________________
b.
Enter the command on each
router and answer the following questions:
1)
How many serial interfaces are
there on R1 and R2? ______________________________________
2)
How many Ethernet
interfaces are there on R1 and R2? ____________________________________
3)
Are all the Ethernet interfaces
on R1 the same? If no, explain the
difference(s).
________________________________________________________________________________
________________________________________________________________________________
________________________________________________________________________________
Step 3:
Display the routing table on R1.
a.
What command displays the
content of the routing table? ______________________________________
b.
Enter the command on R1 and answer the following questions:
1)
How many connected routes are there
(uses the C code)? _______
2)
Which route is listed? ______________________________________
3)
How does a router handle
a packet destined for a network that is not listed in the routing table?
________________________________________________________________________________
________________________________________________________________________________
Part 2:
Configure Router Interfaces
Step 1:
Configure the GigabitEthernet
0/0 interface on R1.
a.
Enter the following commands to
address and activate the GigabitEthernet 0/0 interface on R1:
R1(config)# interface
gigabitethernet 0/0
R1(config-if)# ip address 192.168.10.1 255.255.255.0
R1(config-if)# no shutdown
%LINK-5-CHANGED: Interface GigabitEthernet0/0,
changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface
GigabitEthernet0/0, changed state to up
b.
It
is good practice to configure a description for each interface to help document
the network information. Configure an interface
description indicating to which device it is connected.
R1(config-if)# description LAN connection to S1
c.
R1 should now be able to ping PC1.
R1(config-if)# end
%SYS-5-CONFIG_I: Configured from console by
console
R1# ping
192.168.10.10
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.10.10,
timeout is 2 seconds:
.!!!!
Success rate is 80 percent (4/5), round-trip
min/avg/max = 0/2/8 ms
Step 2:
Configure the remaining Gigabit
Ethernet Interfaces on R1 and R2.
a.
Use the information in the Addressing Table to
finish the interface configurations for R1
and R2. For each interface, do
the following:
1)
Enter the IP address and
activate the interface.
2)
Configure an appropriate
description.
b.
Verify interface
configurations.
Step 3:
Back up the configurations to
NVRAM.
Save the configuration files on both
routers to NVRAM. What command did you use? ___________________
Part 3:
Verify the Configuration
Step 1:
Use verification commands to
check your interface configurations.
a.
Use the show ip interface brief command on both R1 and R2 to quickly
verify that the interfaces are configured with the correct IP address and
active.
How many interfaces on R1 and R2 are configured with IP addresses and in the “up” and “up” state?
___
What part of the interface configuration
is NOT displayed in the command output? __________________
What commands can you use to verify this
part of the configuration?
____________________________________________________________________________________
b.
Use the show ip route command on both R1
and R2 to view the current
routing tables and answer the following questions:
1)
How many connected
routes (uses the C code) do you see
on each router? _______
2)
How many EIGRP routes (uses the
D code) do you see on each router? _______
3)
If the router knows all the
routes in the network, then the number of connected routes and dynamically
learned routes (EIGRP) should equal the total number of LANs and WANs. How many
LANs and WANs are in the topology? _______
4)
Does this number match the
number of C and D routes shown in the routing table? _______
Note: If your answer is
“no”, then you are missing a required configuration. Review the steps in Part 2.
Step 2:
Test end-to-end connectivity
across the network.
You should now be able to ping from any
PC to any other PC on the network. In addition, you should be able to ping the
active interfaces on the routers. For example, the following should tests
should be successful:
·
From the command line on PC1,
ping PC4.
·
From the command line on R2,
ping PC2.
Note: For simplicity in this activity, the switches are not configured;
you will not be able to ping them.
