Objectives
In this Packet Tracer activity, you will troubleshoot and resolve connectivity issues, if possible.
Otherwise, the issues should be clearly documented so they can be escalated.
•
Background / Scenario
Users are reporting that they cannot access the web server,
www.cisco.pka
after a recent
upgrade that included adding a second DNS server. You must determine the cause and
attempt to resolve the issues for the users. Clearly document the issues and any solution(s).
You do not have access to the devices in the cloud or the server
www.cisco.pka
. Escalate the
problem if necessary.
Note:
Router R1 can only be accessed using SSH with the username
Admin01
and
password
cisco12345
. Router R2 is in the ISP cloud and is not accessible by you.
•
Instructions
•
Determine connectivity issues from PC-01.
•
On PC-01, open the command prompt. Enter the command
ipconfig
to verify
what IP address and default gateway have been assigned to PC-01. Correct as
necessary according to the Addressing Table.
•
After verifying/correcting the IP addressing issues on PC-01, issue pings to the
default gateway, web server, and other PCs. Were the pings successful? Record
the results.
Questions:
Ping to default gateway (172.16.1.1)?
Yes
To web server (209.165.201.2)?
Yes
Ping to PC-02?
Yes
To PC-A?
No
To PC-B?
No
•
Use the web browser to access the web server on PC-01. Access the web server
by first entering the URL
http://www.cisco.pka
and then by using the IP address
209.165.201.2. Record the results.
Questions:
Can PC-01 access
www.cisco.pka
?
Yes
Using the web server IP address?
Yes
•
Document the issues and provide the solution(s). Correct the issues if possible.
You have to change the ip address from 172.168.1.3 to 172.16.1.3 PC01 cant
successfully ping the PCs on 172.16.2.0
•
Determine connectivity issues from PC-02.
•
On PC-02, open the command prompt. Enter the command
ipconfig
to verify the
configuration for the IP address and default gateway. Correct as necessary.
•
After verifying/correcting the IP addressing issues on PC-02, issue pings to the
default gateway, web server, and other PCs. Were the pings successful? Record
the results.
Questions:
Ping to default gateway (172.16.1.1)?
Yes
To web server (209.165.201.2)?
Yes
Ping to PC-01?
Yes
To PC-A?
No
To PC-B?

www.cisco.pka
using the web browser on PC-02. Record the results.
Questions:
Can PC-02 access
www.cisco.pka
?
Yes
Using the web server IP address?
Yes
•
Document the issues and provide the solution(s). Correct the issues if possible.
The defult gateway needs to be configured on pc 02 as 172.16.1.1
•
Determine connectivity issues from PC-A.
•
On PC-A, open the command prompt. Enter the command
ipconfig
to verify the
configuration for the IP address and default gateway. Correct as necessary.
•
After correcting the IP addressing issues on PC-A, issue the pings to the web
server, default gateway, and other PCs. Were the pings successful? Record the
results.
Questions:
To web server (209.165.201.2)?
