Introduction

The 
Troubleshooting routing related technologies EIGRP module is part of the series of the troubleshooting modules which takes a different approach to learning from what has previously been used in this course.

Instead of providing you with a set of instructions and walkthroughs on how to configure specific technologies, this module provides you with a pre-configured environment which you will use to hone your troubleshooting and diagnostic skills.

In this module are a number of problems that you will need to diagnose and solve, these are outlined in the symptoms section.

All the issues that are present in the lab are formed from technologies that you have learnt about within the previous modules in this course. You will need to use the skills learnt in those modules to help you resolve the issues that are present in the lab.

There are no walkthroughs!

You will need to follow the process of:

Predicting normal operation

You will need to use any of the information provided within the exercise and the diagram that is shown at the beginning of each section for this. The diagram displays everything about the lab that you need to know, you must trust the diagram to be correct.

Isolate a specific problem

Use your knowledge of 
show commands to locate issues, compare the output from these commands to what is documented in the diagram and within any textual content in this module.

Carry out root cause analysis

Combine both the output of the commands and the diagram to make your configuration changes to resolve the issues that have been documented.

Example

The following example is aimed to help you understand the format of this module.

Note: There is no requirement to execute the commands outlined in this example; they are not part of this lab.

Diagram

Symptom

There is no route in 
NYEDGE2’s routing table for 172.16.15.0/24 which is a loopback interface on 
NYEDGE1.

Troubleshooting

Observing the diagram we can see the following:

· Both routers have two interfaces on the same subnets (172.14.0.0/24 and 192.168.20.16/28)

· Both routers are in EIGRP AS 8001

Using these observations we could predict that EIGRP must be running on at least one of the interfaces on both routers, this interface should be the same on each router. We could also predict that the Loopback10 subnet must also be configured under EIGRP.

Using our knowledge we can focus on the following 
potentialareas that could be causing the communication to fail:

· Incorrect AS numbers

· Incorrect masks on interfaces

· Incorrect EIGRP network statements

· Incorrect hello intervals

· Interface status not up/up

There could be other issues, but this is a good list to start with before we need to get too advanced.

Looking at these areas in sequence, we can use the following process to resolve the communication issue.

Note: This may not be the most effective way to resolve this issue, it simply serves as an example as an approach you could take.

Step 1

First let’s look at the EIGRP AS on either router. To do this we can use the 
show ip protocols command:

NYEDGE1

NYEDGE1#show ip protocols

Routing Protocol is “eigrp 8001”

Outgoing update filter list for all interfaces is not set

Incoming update filter list for all interfaces is not set

Default networks flagged in outgoing updates

Default networks accepted from incoming updates

EIGRP metric weight K1=1, K2=0, K3=1, K4=0, K5=0

EIGRP maximum hopcount 100

EIGRP maximum metric variance 1

Redistributing: eigrp 8001

EIGRP NSF-aware route hold timer is 240s

Automatic network summarization is not in effect

Maximum path: 4

Routing for Networks:

172.16.15.0/24

192.168.20.0/28

Routing Information Sources:

Gateway Distance Last Update

Distance: internal 90 external 170

NYEDGE2

NYEDGE2#show ip protocols

Routing Protocol is “eigrp 8001”

Outgoing update filter list for all interfaces is not set

Incoming update filter list for all interfaces is not set

Default networks flagged in outgoing updates

Default networks accepted from incoming updates

EIGRP metric weight K1=1, K2=0, K3=1, K4=0, K5=0

EIGRP maximum hopcount 100

EIGRP maximum metric variance 1

Redistributing: eigrp 8001

EIGRP NSF-aware route hold timer is 240s

Automatic network summarization is not in effect

Maximum path: 4

Routing for Networks:

192.168.16.0

Routing Information Sources:

Gateway Distance Last Update

Distance: internal 90 external 170

Observing the output from both routers we can see that they are both configured with the same EIGRP AS number 8001.

However, we can also see further down in the output that the routing for networks section doesn’t look correct on 
NYEDGE2. We are seeing a network of 192.168.16.0/24 which doesn’t exist in the diagram.

Observing the same list in 
NYEDGE1, we could predict that this should be the 192.168.20.0 network instead. As 
NYEDGE1 is not configured to run EIGRP on the 172.14.0.0/24 network, we can assume that we shouldn’t run EIGRP on this interface.

Correct this configuration error:

NYEDGE2#configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

NYEDGE2(config)#router eigrp 8001

NYEDGE2(config-router)#no network 192.168.16.0

NYEDGE2(config-router)#network 192.168.20.16 0.0.0.15

Confirm if this configuration change has corrected this issue we can view the EIGRP neighbors table, or of course the routing table.

NYEDGE2#show ip eigrp neighbors

IP-EIGRP neighbors for process 8001

NYEDGE2#

It appears the table is still empty, indicating this wasn’t the only issue.

Step 2

Let’s confirm the EIGRP configuration on 
NYEDGE1:

NYEDGE1#show run | section eigrp

router eigrp 8001

network 172.16.15.0 0.0.0.255

network 192.168.20.0 0.0.0.15

no auto-summary

Now, take a very close look at the diagram and at this output. This is a very subtle mistake made in the configuration when looking at the diagram.

The network statement that is configured for the 192.168.20 subnet is actually incorrect. The subnet address is not 192.168.20.0/28 it is in fact 192.168.20.16/28.

Correcting this issue:

NYEDGE1#configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

NYEDGE1(config)#router eigrp 8001

NYEDGE1(config-router)#no network 192.168.20.0 0.0.0.15

NYEDGE1(config-router)#network 192.168.20.16 0.0.0.15

NYEDGE1(config-router)#

Aug 12 07:09:33.783: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 8001: Neighbor 192.168.20.18 (GigabitEthernet0/0) is up: new adjacency

Instantly we see the neighbour adjacency come up.

Confirming that the route is now present on 
NYEDGE2:

NYEDGE2#show ip route

Codes: C – connected, S – static, R – RIP, M – mobile, B – BGP

D – EIGRP, EX – EIGRP external, O – OSPF, IA – OSPF inter area

N1 – OSPF NSSA external type 1, N2 – OSPF NSSA external type 2

E1 – OSPF external type 1, E2 – OSPF external type 2

i – IS-IS, su – IS-IS summary, L1 – IS-IS level-1, L2 – IS-IS level-2

ia – IS-IS inter area, * – candidate default, U – per-user static route

o – ODR, P – periodic downloaded static route

Gateway of last resort is not set

172.14.0.0/24 is subnetted, 1 subnets

C 172.14.0.0 is directly connected, GigabitEthernet0/1

172.16.0.0/24 is subnetted, 1 subnets

D 172.16.15.0 [90/156160] via 192.168.20.17, 00:00:55, GigabitEthernet0/0

192.168.20.0/28 is subnetted, 1 subnets

C 192.168.20.16 is directly connected, GigabitEthernet0/0

This very subtle 
typo has had a drastic impact in our network. It’s often that these human mistakes occur in the real world and typically they are hard to spot because it may not be the entire statement that’s incorrect, just a small part of it.

You may also experience multiple issues, as in this case.

You can see that by using your knowledge that you have learnt in this course and using a logical approach to troubleshooting, you will be able to resolve the issues documented in this module.

Connecting to your lab

Exercise 1 – Troubleshooting EIGRP

The configurations that have been applied to the devices within this lab have a number of incorrect settings and are causing numerous problems.

This exercise rolls up all your troubleshooting and configuration skills learnt within the modules of this course. You will need to use all of these skills to correct the configurations on each of the devices such that you resolve the symptoms that have been noted in the symptoms list below.

Pay close attention to the diagram shown below, 
this diagram will give you all the information you need to fix the issues. As with any real world scenario, if there is something you don’t understand, you may need to refer to your favourite search engine to gain some additional understanding on a particular technology.

Symptoms

The following symptoms have been observed. Use your skills and the information in the diagram below to resolve them.

· Server PLABCSCO01 is receiving intermittent ping replies from 172.16.16.1 as shown in the image below after this list.

· The route for 10.16.18.0/24 is going via NYEDGE2 and not directly via NYEDGE1 as it should when using a traceroute from PLABCSCO01.

· NYCORE2 has no EIGRP adjacencies.

· There is an incorrect route entry for 192.168.16.0, there should only be a /24 route in any of the routing tables for this subnet.

· There is no load balancing between NYWAN1 serial interfaces s0/0/0.641 and s0/0/0.256

· The route for 172.16.10.128/25 is not being advertised.

· The route for 172.16.11.0/28 is not being advertised.

· The route for 172.16.11.128/28 is not being advertised.

Intermittent ping results on 
PLABCSCO01 while pinging 172.16.16.1:

Issue hints:

While diagnosing the problems outlined above you will need to check things such as:

· Autonomous system numbers

· Correct masks applied to interfaces

· Correct network addresses (including the mask) under the EIGRP configuration

· Correct hello intervals

· Correct interface status

· Correct variance statement

Diagram

Use this diagram as a reference to how the network should be configured for correct operation.

End results

The diagram above is correct and how the lab should be configured for optimal data transmission.

If you have resolved all the issues your ping between 
PLABCSCO01 and 172.16.16.1 should be stable without any errors.

You should see the following routes on 
NYWAN1:

· 172.16.10.128/25

· 172.16.11.0/28

· 172.16.11.128/28

You should see multiple routing entries for the following network addresses on 
NYWAN1:

· 192.168.224.0/24

· 192.168.225.0/24

· 192.168.226.0/27

· 192.168.226.32/27

The next hop for 10.16.18.0/24 on 
NYCORE1 should point directly to 
NYEDGE1, not via 
NYEDGE2

Exercise 2 – Resolutions

This exercise does not cover fixing the actual problems outlined in exercise 1. Instead, this exercise serves as a list of configuration items that you should have resolved.

Problem 1

Incorrect hello timer.

Problem 2

Incorrectly configured passive-interface.

Problem 3

Incorrectly configured Autonomous System number.

Problem 4

Incorrect IP address configuration on SVI.

Problem 5

No variance command under EIGRP.

Problem 6

Missing network statement under EIGRP.

Problem 7

Interface is shutdown.

Problem 8

Incorrect network statement under EIGRP.

Summary

In this module you analysed and hopefully resolved the configuration errors for the following technologies:

· Incorrectly configured EIGRP AS numbers.

· Incorrect hello intervals.

· Missing or incorrect network statements.

· Passive interfaces.

· Missing or incorrect variance commands.

· Incorrectly configured IP addresses.
