Objectives
Troubleshoot network issues related to the configuration and operation of IP SLAs and Netflow.
Background / Scenario
In this topology, R1 and R3 are boundary routers for BGP AS 138. They are both connected to R2. R2 is a boundary router for BGP AS 77. R1 and R3 are adjacent with D1 and D2 via OSPFv3 Address Families for both IPv4 and IPv6. R1 and R3 are both providing default routes to the OSPF network. The default routes are configured to be OSPF External Type 1 routes. Switches D1 and D2 are performing inter-VLAN routing for VLANs 3, 8, and 13. Switches D1 and D2 are providing gateway redundancy using HSRP version 2. The virtual router for each VLAN uses the host address .254. Switches D1 and D2 are also providing DHCP services for IPv4 clients. IPv6 clients use SLAAC. 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) and Cisco Catalyst 2960 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 devices have been erased and have no startup configurations. If you are unsure, contact your instructor.
Note: The default Switch Database Manager (SDM) template on a Catalyst 2960 does not support IPv6. You must change the default SDM template to the dual-ipv4-and-ipv6 default template using the sdm prefer dual-ipv4-and-ipv6 default global configuration command. Changing the template will require a reboot.
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 Switch (Cisco 2960 with Cisco IOS Release 15.2(2) lanbasek9 image or comparable)
- 3 PCs (Choice of operating system with terminal emulation program and a packet capturing utility 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 23.1.4.1
Scenario:
You tasked the junior network administrators working over the weekend to deploy and test IP SLAs on switches D1 and D2 so that they would relinquish the HSRP Active Role if an upstream interface were to go down. The reports you receive on Monday morning state that the SLAs are in place, but HSRP is not behaving as expected. They need your expertise to figure out what is wrong.
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.
Device |
Command |
R1 |
copy flash:/enarsi/23.1.4.1-r1-config.txt run |
R2 |

R3 |

- PC1 must have the addresses shown in the topology diagram statically assigned. PC2 and PC3 will receive their addresses dynamically.
- Passwords on all devices are cisco12345. If a username is required, use admin.
- 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 repeated for the IPv4 SLA and the IPv6 SLA. This one error is repeated on D1 and D2. The junior administrator concentrated so much on building and assigning the tracking mechanism, he forgot to actually start the SLAs.
The commands used to fix these errors should be:
D1(config)# ip sla schedule 14 life forever start-time now
D1(config)# ip sla schedule 16 life forever start-time now
D2(config)# ip sla schedule 14 life forever start-time now
D2(config)# ip sla schedule 16 life forever start-time now
Part 2: Trouble Ticket 23.1.4.2
Note: This ticket only works on 4000-series routers. If the routers in use are ISR G2 series (29/39xx series), use trouble ticket 23.1.4.3 instead.
Scenario:
Management is asking for detailed information on traffic flowing in and out of the network. They want this information to help shape updates to the organizational security policy, as well as get an idea about bandwidth utilization. Your intention is to configure Flexible Netflow to gather information on traffic entering and exiting the OSPF interfaces on R1 and R3. After a lot of work sorting out how to configure the technology, you thought you had it configured, but the collector at PC1 is still not receiving any data.
Use the commands listed below to load the configuration files for this trouble ticket:

Answers Notes:
This trouble ticket contains 1 intentional error repeated on R1 and R3. The administrator concentrated so much on crafting the capture information so that it contained useful statistics, he forgot to configure the interface to actually collect the data.
The commands used to fix this error should be:
R1(config)# interface g0/0/1
R1(config-if)# ip flow monitor 2314-INBOUND-MON input
R1(config-if)# ip flow monitor 2314-OUTBOUND-MON output
R1(config-if)# end
R3(config)# interface g0/0/1
R3(config-if)# ip flow monitor 2314-INBOUND-MON input
R3(config-if)# ip flow monitor 2314-OUTBOUND-MON output
R3(config-if)# end
To prove the fix, run Wireshark on PC1 and set the filter to udp.dstport == 9999. Packets from 172.16.0.1 and 172.16.1.1 will be displayed.
Part 3: Trouble Ticket 23.1.4.3
Note: This ticket only works on ISR G2 series (29/39xx series) routers. If the routers in use are from the 4000-series, use trouble ticket 23.1.4.2 instead.
Scenario:

They want this information to help shape updates to the organizational security policy, as well as get an idea about bandwidth utilization. Your job is to configure Netflow to gather information on traffic entering and exiting the OSPF interfaces on R1 and R3. This is a new technology for you, but you think you have worked out how to configure it, unfortunately the collector at PC1 is still not receiving any data.

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+ ] {

D1/D2 (Cisco 3650) Reset Script – The default 3650 SDM template supports IPv6, so it is not set by this script.
