Objectives
Troubleshoot network issues related to the configuration and operation of EIGRP for IPv4.
Background / Scenario
In this topology, routers R1, R2, and R3 are EIGRP neighbors. Switches D1 and D2 provide connectivity between R1 and R3. Router R1 is configured for inter-VLAN routing and DHCP to provide support for PC 1. You will be loading configurations with intentional errors onto the network. Your tasks are to FIND the error(s), document your findings and the command(s) or method(s) used to fix them. FIX the issue(s) presented here and then test the network to ensure both of the following conditions are met:
1) the complaint received in the ticket is resolved
2) full reachability is restored
Note: The routers used with CCNP hands-on labs are Cisco 4221 with Cisco IOS XE Release 16.9.4 (universalk9 image). The switches used in the labs are Cisco Catalyst 3650s with Cisco IOS XE Release 16.9.4 (universalk9 image) and Cisco Catalyst 2960s with Cisco IOS Release 15.2(2) (lanbasek9 image). Other routers, switches, and Cisco IOS versions can be used. Depending on the model and Cisco IOS version, the commands available and the output produced might vary from what is shown in the labs. Refer to the Router Interface Summary Table at the end of the lab for the correct interface identifiers.
Note: Make sure that the switches have been erased and have no startup configurations. If you are unsure, contact your instructor.
Instructor Note: Refer to the Instructor Lab Manual for the procedures to initialize and reload devices.
Required Resources

• 2 Switches (Cisco 3560 with Cisco IOS XE Release 16.9.4 universal image or comparable)
• 1 PC (Choice of operating system with terminal emulation program installed)
• Console cables to configure the Cisco IOS devices via the console ports
• Ethernet cables as shown in the topology
Instructions
Part 1: Trouble Ticket 4.1.2.1
Scenario:
R2 was added to the network to increase bandwidth for traffic between the R1 and R3 LANs. However, R2, is not sending routes to R1 or forming adjacencies with R3.
Use the commands listed below to load the configuration files for this trouble ticket:
Instructor Note: Commands for uploading the configuration are provided at the end of this document.
Device | Command |
---|---|
R1 | copy flash:/enarsi/4.1.2.1-r1-config.txt run |
R2 | copy flash:/enarsi/4.1.2.1-r2-config.txt run |
R3 | copy flash:/enarsi/4.1.2.1-r3-config.txt run |
D1 | copy flash:/enarsi/4.1.2.1-d1-config.txt run |
D2 | copy flash:/enarsi/4.1.2.1-d2-config.txt run |
• PC 1 should be configured for and receive an address from an IPv4 DHCP server.
• Passwords on all devices are cisco12345. If a username is required, use admin.
• After you have fixed the ticket, change the MOTD on EACH DEVICE using the following command:
banner motd # This is $(hostname) FIXED from ticket <ticket number> #
• Then save the configuration by issuing the wri command (on each device).
• Inform your instructor that you are ready for the next ticket.
• After the instructor approves your solution for this ticket, issue the reset.now privileged EXEC command on each device. This script will clear your configurations and reload the devices.
Instructor Notes:
This trouble ticket contains two intentional errors:
1) R2 is configured with the same Router-ID as R1
2) R3 has interface g0/0/0 marked passive
The commands used to fix these errors should be:
R2(config)# router eigrp 412 R2(config-router)# eigrp router-id 2.2.2.2 R2(config-router)# end R3(config)# router eigrp 412 R3(config-router)# no passive-interface g0/0/0 R3(config-router)# end
Note: Student may choose to issue the command no passive-interface default
. This solves the adjacency issue with R2 but would open the router up to possible undesired adjacencies if there were more L3 interfaces configured.
Part 2: Trouble Ticket 4.1.2.2
Scenario:
Your company hired an outside security consultant to work on the network. His task was to ensure that routing was being done securely. After he completed his work, R2 stopped sharing route information about networks at R1.
Use the commands listed below to load the configuration files for this trouble ticket:
Instructor Note: Commands for creating these files are at the end of this document.

• Then save the configuration by issuing the wri command (on each device).
• Inform your instructor that you are ready for the next ticket.
• After the instructor approves your solution for this ticket, issue the reset.now privileged EXEC command. This script will clear your configurations and reload the devices.
Instructor Notes:
This trouble ticket contains 1 intentional error. R2 has a distribute list that is blocking the networks. The distribute list should be removed.
The commands used to fix these errors should be:
R2(config)# router eigrp 412 R2(config-router)# no distribute-list prefix 88QRX-T13 out g0/0/1 R2(config-router)# end

Note: To find out how the router is configured, look at the interfaces to identify the type of router and how many interfaces the router has. There is no way to effectively list all the combinations of configurations for each router class. This table includes identifiers for the possible combinations of Ethernet and Serial interfaces in the device. The table does not include any other type of interface, even though a specific router may contain one. An example of this might be an ISDN BRI interface. The string in parenthesis is the legal abbreviation that can be used in Cisco IOS commands to represent the interface.
Uploading Configuration Files
Use the commands below to create the configuration files on the lab devices for each trouble ticket in this lab. The TCL script commands help create and copy the configurations. However, the configuration commands could also be copied and pasted directly into global config mode on each device. Simply remove the TCL script commands, enter the enable and configure t commands on the device, and copy and paste the configuration commands.
Important: The device requires a folder in flash named enarsi. Use the dir command to verify. If the folder is missing, then create it using the mkdir flash:/enarsi privileged EXEC command. For all switches, make sure the vlan.dat file is set to the default. Use the delete vlan.dat privileged EXEC command, if necessary.
Reset scripts
These TCL scripts will completely clear and reload the device in preparation for the next ticket. Copy and paste the appropriate script to the appropriate device.
Router Reset Script
tclsh puts [ open "flash:/enarsi/reset.tcl" w+ ] { typeahead "\n" copy running-config startup-config typeahead "\n" erase startup-config puts "Reloading the router" typeahead "\n" reload } tclquit
D1/D2 (Cisco 3650) Reset Script – The default 3650 SDM template supports IPv6, so it is not set by this script.
tclsh puts [ open "flash:/enarsi/reset.tcl" w+ ] { typeahead "\n" copy running-config startup-config typeahead "\n" erase startup-config delete /force vlan.dat puts "Reloading the switch" typeahead "\n" reload } tclquit
A1 (Cisco 2960 Script) – The default 2960 SDM template does not support IPv6, so this script includes that setting.
tclsh puts [ open "flash:/enarsi/reset.tcl" w+ ] { typeahead "\n" copy running-config startup-config typeahead "\n" erase startup-config delete /force vlan.dat delete /force multiple-fs ios_config "sdm prefer lanbase-routing" typeahead "\n" puts "Reloading the switch in 1 minute, type reload cancel to halt" typeahead "\n" reload } tclquit
