Instructor Note: Red font color or gray highlights indicate text that appears in the instructor copy only.

Objectives

Troubleshoot network issues related to redistribution.

Background / Scenario

In this topology D1, R1, and R2 are implementing OSPFv2. D1 is redistributing Loopback 0 into OSPFv2 area 10. R2 and R3 are BGP neighbors in AS 64512. You will be loading configurations with intentional errors or missing configurations 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.

Instructor Note: Refer to the Instructor 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

Scenario:

During a routine maintenance window, router R2 was replaced and upgraded to support gigabit interfaces. Instead of modifying the previous R2 configuration to support gigabit interfaces and loading the configuration file on R2, the network engineer decided to type the IOS commands on R2 from memory. As a result, only partial redistribution is occurring between OSPFv2 and BGP. The network engineer requested your help in diagnosing and resolving the issue(s) to restore full connectivity.

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/17.1.2.1-r1-config.txt run
R2 copy flash:/enarsi/17.1.2.1-r2-config.txt run
R3 copy flash:/enarsi/17.1.2.1-r3-config.txt run
D1 copy flash:/enarsi/17.1.2.1-d1-config.txt run

• 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> #
• 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 two intentional errors:

1) By default, BGP only redistributes eBGP routes into an Interior Gateway Protocol, such as OSPF. To redistribute iBGP routes into OSPF requires the bgp redistribute-internal command.
2) By default, when redistributing OSPF into BGP only intra-area and inter-area OSPF routes are “matched” for redistribution. To redistribute external OSPF routes required the redistribute ospf 1 match internal external 1 external 2 command.

The commands used to fix the first error should be:

R2(config)# router bgp 64512
R2(config-router)# address-family ipv4
R2(config-router-af)# bgp redistribute-internal
R2(config-router-af)# end

The commands used to fix the second error should be:

R2(config)# router bgp 64512
R2(config-router)# address-family ipv4
R2(config-router-af)# redistribute ospf 1 match internal external 1 external 2
R2(config-router-af)# end

Scenario:

R2 is performing route redistribution between OSPFv3 AF and Named EIGRP for IPv4 and IPv6. During a routine maintenance window, router R2 was upgraded. As a result, redistribution is not occurring for IPv4 between OSPFv3 and named EIGRP.

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

Device Command
R1 copy flash:/enarsi/17.1.2.2-r1-config.txt run
R2 copy flash:/enarsi/17.1.2.2-r2-config.txt run

D2 copy flash:/enarsi/17.1.2.2-d2-config.txt run

• 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> #
• 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, proceed to troubleshoot IPv6 redistribution.

Instructor Notes:

This IPv4 trouble ticket contains two intentional errors:

1) OSPFv3 routes being redistributed into EIGRP are not getting the correct seed metric within the route map.
2) Redistribution of EIGRP routes into OSPFv3 is configured with the wrong EIGRP AS number.

The commands used to fix the first error should be:

R2(config)# no route-map OSPF-into-EIGRP permit 10
R2(config)# route-map OSPF-into-EIGRP permit 10
R2(config-route-map)# set metric 1000000 10 255 1 1500

The commands used to fix the second error should be:

R2(config)# router ospfv3 1
R2(config-router)# address-family ipv4
R2(config-router-af)# no redistribute EIGRP 64521 metric 25 metric-type 1
R2(config-router-af)# redistribute EIGRP 64512 metric 25 metric-type 1

Scenario:

R2 is performing route redistribution between OSPFv3 AF and Named EIGRP for IPv4 and IPv6. During a routine maintenance window router R2 was upgraded. As a result, IPv6 has limited connectivity and only partial redistribution is occurring between OSPFv3 and named EIGRP for IPv6.

Use the previously loaded 17.1.2.2 configuration files for trouble ticket 17.1.2.3:

• 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> #
• 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 IPv6 trouble ticket contains two intentional errors:

1) OSPFv3 routes being redistributed into named EIGRP require a seed metric.
2) The Loopback 0 Ipv6 address on S2 is being filtered during redistribution into OSPFv3.

The commands used to fix the first error should be:

R2(config)# router eigrp CISCO
R2(config-router)# address-family ipv6 autonomous-system 64512
R2(config-router-af)# topology base
R2(config-router-af-topology)# default-metric 1000000 10 255 1 1500

or

R2(config-router-af-topology)# redistribute ospf 1 metric 1000000 10 255 1 1500 include-connected

The commands used to fix the second error should be:

R2(config)# ipv6 prefix-list EIGRP-into-OSPF seq 10 permit 2001:DB8::/32 ge 80 le 80

or

R2(config)# no ipv6 prefix-list EIGRP-into-OSPF seq 5 permit 2001:DB8::/32 ge 64 le 64
R2(config)# ipv6 prefix-list EIGRP-into-OSPF seq 5 permit 2001:DB8::/32 ge 64 le 80

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"
