[CCNAv6 S1] 11.3.2.3 Packet Tracer - Test Connectivity with Traceroute



Packet Tracer - Testing Connectivity with Traceroute
Objectives

Part 1: Test End-to-End Connectivity with the tracert Command

Part 2: Compare to the traceroute Command on a Router

Background

This activity is designed to help you troubleshoot network connectivity issues using commands to trace the route from source to destination. You are required to examine the output of tracert (the Windows command) and traceroute (the IOS command) as packets traverse the network and determine the cause of a network issue. After the issue is corrected, use the tracert and traceroute commands to verify the completion.

Part 1:     Test End-to-End Connectivity with the tracert Command
Step 1:     Send a ping from one end of the network to the other end.

Click PC1 and open the Command Prompt. Ping PC3 at 10.1.0.2. What message is displayed as a result of the ping?

Step 2:     Trace the route from PC1 to determine where in the path connectivity fails.

a.     From the Command Prompt of PC1, enter the tracert 10.1.0.2 command.

b.    When you receive the Request timed out message, press Ctrl+C. What was the first IP address listed in the tracert output?

c.     Observe the results of the tracert command. What is the last address reached with the tracert command?

Step 3:     Correct the network problem.

a.     Compare the last address reached with the tracert command with the network addresses listed on the topology. The furthest device from the host 10.0.0.2 with an address in the network range found is the point of failure. What devices have addresses configured for the network where the failure occurred?

b.    Click RouterC and then the CLI tab. What is the status of the interfaces?

c.     Compare the IP addresses on the interfaces with the network addresses on the topology. Does there appear to be anything extraordinary?

d.    Make the necessary changes to restore connectivity; however, do not change the subnets. What is solution?

Step 4:     Verify that end-to-end connectivity is established.

a.     From the PC1 Command Prompt, enter the tracert 10.1.0.2 command.

b.    Observe the output from the tracert command. Was the command successful?

Part 2:     Compare to the traceroute Command on a Router
a.     Click RouterA and then the CLI tab.

b.    Enter the traceroute 10.1.0.2 command. Did the command complete successfully?

c.     Compare the output from the router traceroute command with the PC tracert command. What is noticeably different about the list of addresses returned?

Part 3:     Using Extended Traceroute
In addition to traceroute, Cisco IOS also includes extended traceroute. Extended traceroute allows the administrator to adjust minor traceroute operation parameters by asking simple questions.
As part of the verification process, use extended traceroute on RouterA to increase the number of ICMP packets traceroute sends to each hop.
Note: Windows tracert also allows the user to adjust a few aspects through the use of command line options.
a.     Click RouterA and then the CLI tab.

b.    Enter the traceroute and press ENTER. Notice that just the traceroute command should be entered.

c.     Answer the questions asked by extended traceroute as follows. Extended traceroute should run right after the last question is answered.

Protocol [ip]: ip
Target IP address: 10.1.0.2
Source address: 10.100.100.1
Numeric display [n]: n
Timeout in seconds [3]: 3
Probe count [3]: 5
Minimum Time to Live [1]: 1
Maximum Time to Live [30]: 30
Note: the value displayed in brackets is the default value and will be used by traceroute if no value is entered. Simply press ENTER to use the default value.
How many questions were answered with non-default values? What was the new value?
How many ICMP packets were sent by RouterA?
Note: Probe count specifies the number of ICMP packets sent to each hop by traceroute. A higher number of probes allows for a more accurate average round trip time for the packets.

d.    Still on RouterA, run extended traceroute again but this time change the timeout value to 7 seconds.

What happened? How does the different timeout value affect traceroute?

Can you think of a use for the timeout parameter?







Configuration RouterC:

enable
configure terminal
interface s0/0/0
 no ip address
 ip address ip address 10.100.100.9 255.255.255.252
 exit
!



END!!

Packet Tracer - Configuring IPv4 Static and Default Routes Addressing Table Objectives Part 1: Examine the Network and Evaluate the Need for Static Routing Part 2: Configure Static and Default Routes Part 3: Verify Connectivity Background In this activity, you will configure static and default routes. A static route is a route that is entered manually by the network administrator to create a reliable and safe route. There are four different static routes that are used in this activity: a recursive static route, a directly attached static route, a fully specified static route, and a default route. Part 1:     Examine the Network and Evaluate the Need for Static Routing a.     Looking at the topology diagram, how many networks are there in total? b.    How many networks are directly connected to R1, R2, and R3? c.     How many static routes are required by each router to reach networks that are not directly connected? d.    Test connectivity to the R2 and R3

Packet Tracer – Skills Integration Challenge Addressing Table VLAN Port Assignments and DHCP Information Scenario In this culminating activity, you will configure VLANs, trunks, DHCP Server, DHCP relay agents, and configure a router as a DHCP client. Requirements Using the information in the tables above, implement the following requirements: ·         Create VLANs on S2 and assign VLANs to appropriate ports. Names are case-sensitive ·         Configure S2 ports for trunking. ·         Configure all non-trunk ports on S2 as access ports. ·         Configure R1 to route between VLANs. Subinterface names should match the VLAN number. ·         Configure R1 to act as a DHCP server for the VLANs attached to S2. -       Create a DHCP pool for each VLAN. Names are case-sensitive. -       Assign the appropriate addresses to each pool. -       Configure DHCP to provide the default gateway address -       Configure the DNS server 209.165.201.14 for each pool. -

Packet Tracer – Troubleshooting EIGRP for IPv4 Addressing Table Scenario In this activity, you will troubleshoot EIGRP neighbor issues. Use show commands to identify errors in the network configuration. Then, you will document the errors you discover and implement an appropriate solution. Finally, you will verify full end-to-end connectivity is restored. Troubleshooting Process 1.     Use testing commands to discover connectivity problems in the network and document the problem in the Documentation Table. 2.     Use verification commands to discover the source of the problem and devise an appropriate solution to implement. Document the proposed solution in the Documentation Table. 3.     Implement each solution one at a time and verify if the problem is resolved. Indicate the resolution status in the Documentation Table. 4.     If the problem is not resolved, it may be necessary to first remove the implemented solution before returning to Step 2. 5.     Once al
