Topology

Addressing Table

Note: To make it easier to recognize IPv6 prefixes, familiarize yourself with the IPv6 GUA and LLA address formats.

• GUA: The GUA has a 16-bit subnet-ID, a<area-id>xx (“a” for area). For example, subnet-ID a201 is area 2, network 01.
• LLA: Following best practice the LLA address is unique on each interface. The LLA interface-ID uses the GUA subnet-ID:interface-ID for the last 64 bits. For example, fe80::a201:1 has an LLA interface-ID a201 (the subnet-ID of the GUA) and :1 (the Interface ID of the GUA).

Objectives

Troubleshoot network issues related to the configuration and operation of OSPFv3.

Background / Scenario

Although the topology has a limited number of routers, you should use the appropriate troubleshooting commands to help find and solve the problems in the three trouble tickets as if this were a much more complex topology with many more routers and networks.

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 3650 with Cisco IOS XE Release 16.9.4 (universalk9 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 devices have been erased and have no startup configurations. If you are unsure, contact your instructor.

Answers Note: Refer to the Answers Lab Manual for the procedures to initialize and reload devices.

Required Resources

• 3 Routers (Cisco 4221 with Cisco IOS XE Release 16.9.4 universal image or comparable)
• 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 10.1.2.1

Scenario:

Your University network has migrated to IPv6-only internally and is using multiarea OSPFv3 address families. Recently your team configured all the necessary devices for this migration, with different people responsible for configuring different parts of the network.

During testing and validation, the network team noticed that routers are not showing the 2001:db8:acad:a202::/64 prefix in their routing tables.

Use the commands listed below to load the configuration files for this trouble ticket:

Answers Note: Commands for uploading the configuration are provided at the end of this document.

• All routers should have the 2001:db8:acad:a202::/64 network in their routing tables.
• All devices should be able to ping 2001:db8:acad:a202::2/64.
• When 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> #

• 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.

Answers Notes:

This trouble ticket contains an intentional error:

• R2 is configured for traditional OSPFv3 and not OSPFv3 AF. These two routing processes do NOT share routing information.

The commands used to fix these errors should be:

R2(config)# no ipv6 router ospf 1

R2(config)# router ospfv3 1

R2(config-router)# address-family ipv6 unicast

R2(config-router-af)# router-id 2.2.2.2

R2(config-router-af)# exit

R2(config-router)# inter g 0/0/0

R2(config-if)# no ipv6 ospf 1 area 2

R2(config-if)# ospfv3 1 ipv6 area 2

R2(config-if)# exit

R2(config)# inter lo 0

R2(config-if)# no ipv6 ospf 1 area 2

R2(config-if)# ospfv3 1 ipv6 area 2

R2(config-if)# exit

Part 2:Trouble Ticket 10.1.2.2

Scenario:

After a regularly scheduled downtime for maintenance and IOS upgrades, users started reporting to the helpdesk that there is no access to the IPv6 prefix in area 3. Although there are backups for all device configurations it is suspected that there some of the backups might not have been correct.

You have been tasked to find and resolve the issue with reaching the IPv6 prefix in area 3.

Use the commands listed below to load the configuration files for this trouble ticket:

Answers Note: Commands for creating these files are at the end of this document.

• All routers should have the 2001:db8:acad:a301::/64 network in their routing tables.
• All devices should be able to ping 2001:db8:acad:a301::1/64.
• When 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. This script will clear your configurations and reload the devices.

Answers Notes:

This trouble ticket contains 1 intentional error. Router R3 was not configured with an OSPFv3 router ID. Because R3 does not have any interfaces with IPv4 addresses, the OSPF process was unable to create a 32-bit router ID.

The commands used to fix these errors should be:

R3(config-router)# router ospfv3 1

R3(config-router)# address-family ipv6 unicast

R3(config-router-af)# router-id 3.3.3.3

Part 3:Trouble Ticket 10.1.2.3

Scenario:

Network technicians recently installed a new router, R2 to area 2. However, during the verification phase the technicians are reporting that the other routers are not including the 2001:db8:acad:a202::/64 prefix in their routing tables. They call you for assistance.

Use the commands listed below to load the configuration files for this trouble ticket:

Answers Note: Commands for creating these files are at the end of this document.

Note: To simulate the link being cut, shutdown the G0/0/1 interface on R3:

• PC1 should be able to ping 2001:db8:acad:a301::1.
• Network 2001:db8:acad:a301::/64 must be in its own area.
• When 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> #

• 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.

Answers Notes:

This trouble ticket contains 1 intentional error. On R2 the hello-interval is 5 but the dead-interval was not configured. By default, OSPF uses 4 times the hello-interval, which results in 20 seconds for R2. R1 is the adjacent router and is configured with a hello-interval of 5 and a dead-interval of 15.

The commands used to fix these errors should be:

R2(config)# inter g 0/0/0

R2(config-if)# ospfv3 dead-interval 15

Uploading Configuration Files

Use the commands below to create the configuration files for each trouble ticket in this lab on the lab devices. 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”

}

tclquit

D1/D2 (Cisco 3650) Reset Script – The default 3650 SDM template supports IPv6 by default, 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: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”
