Objectives

Part 1: Build the Network and Configure Basic Device Settings

Part 2: Verify OSPFv3 AF Neighborships and Routing for IPv4 and IPv6

Part 3: Verify EIGRP Neighborships and Routing for IPv4 and IPv6

Part 4: Configure Redistribution from OSPFv3 to EIGRP

Part 5: Configure Redistribution from EIGRP to OSPFv3

Background / Scenario

In this lab, you will configure redistribution from OSPF into EIGRP for IPv4 and IPv6, and redistribution of EIGRP into OSPF for IPv4 and IPv6. You will also change the metric type for EIGRP routes redistributed into OSPF.

D1, R1 and R2 are configured with OSPFv3 for IPv4 and IPv6 address families, while R2, R3 and D2 are configured with EIGRP using named mode for IPv4 and IPv6 address families.

Note: This lab is an exercise in configuring and verifying two-way route redistribution on R2. Route redistribution in this lab does not reflect networking best practices.

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.

Note: Make sure that all 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.

Part 2:Verify OSPFv3 AF Neighborships and Routing for IPv4 and IPv6

In this part, you will verify that OSPF has established neighbor relationships and routing for IPv4 and IPv6.

Step 1:Verify OSPFv3 AF neighborships on R1.

1. Verify R1 has OSPFv3 neighbors: two neighbors from IPv4 address family and two from IPv6 address family.

Open configuration window

R1# show ospfv3 neighbor

2. The output shows four OSPFv3 neighbors: two neighbors from IPv4 address family and two from IPv6 address family.

Close configuration window

Step 2:Verify the IPv4 OSPFv3 routing table on R2.

1. Verify the OSPFv3 IPv4 routing table on R2. Notice the default route, the intra–area, and inter–area OSPF routes are installed and received from 10.1.12.1, which is R1.

Open configuration window

R2# show ip route ospfv3 | begin Gateway

Gateway of last resort is 10.1.12.1 to network 0.0.0.0

O*E20.0.0.0/0 [110/1] via 10.1.12.1, 02:41:28, GigabitEthernet0/0/0

10.0.0.0/8 is variably subnetted, 8 subnets, 2 masks

O10.1.1.0/24 [110/1] via 10.1.12.1, 02:49:12, GigabitEthernet0/0/0

O IA10.1.11.0/24 [110/2] via 10.1.12.1, 02:44:58, GigabitEthernet0/0/0

2. From R2, ping the Loopback 0 address on D1. The ping should be successful.

R2# ping 209.165.201.1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 209.165.201.1, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/2 ms

Step 3:Verify IPv6 OSPFv3 routing table on R2.

1. Verify the OSPFv3 IPv4 routing table on R2. Notice the default route, the intra–area, and inter–area OSPF routes are installed and received from fe80::12:1, which is R1.

R2# show ipv6 route ospf

< some output omitted>

OE2 ::/0 [110/1], tag 1

via FE80::12:1, GigabitEthernet0/0/0

O2001:DB8:ACAD:1::/64 [110/2]

via FE80::12:1, GigabitEthernet0/0/0

OI2001:DB8:ACAD:11::/64 [110/2]

via FE80::12:1, GigabitEthernet0/0/0

2. From R2, ping the IPv6 Loopback 0 address on D1. The ping should be successful.

R2# ping 2001:db8:209:165:201::1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 2001:DB8:209:165:201::1, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/3 ms

3. The output for the ping in the previous step and this step confirms that R2 has learned OSPFv3 routes for IPv4 and IPv6, including a default route for IPv4 and IPv6. The output also confirms R2 can ping the Loopback 0 address from both IPv4 and IPv6.

Part 3:Verify EIGRP Neighborships and Routing for IPv4 and IPv6

In this part, you will verify that EIGRP has established neighbor relationships and routing for IPv4 and IPv6.

Step 1:Verify EIGRP for IPv4 neighborships on R3.

Issue the command to verify EIGRP has two IPv4 neighbors, as shown.

Close configuration window

Step 3:Verify EIGRP for IPv4 routing table on R2.

Issue the command to display the EIGRP IPv4 routing table on R2, as shown.

Open configuration window

R2# show ip route eigrp | begin 10.0

10.0.0.0/8 is variably subnetted, 8 subnets, 2 masks

D10.1.32.0/24 [90/15360] via 10.1.23.3, 20:35:38, GigabitEthernet0/0/1

D10.3.3.0/24 [90/10880] via 10.1.23.3, 20:44:06, GigabitEthernet0/0/1

198.51.100.0/25 is subnetted, 1 subnets

D198.51.100.0 [90/16000] via 10.1.23.3, 20:29:04, GigabitEthernet0/0/1

Notice three internal EIGRP routes from 10.1.23.3, which is R3.

Step 4:Verify EIGRP for IPv6 routing table on R2.

Issue the command to display the IPv6 EIGRP routing table on R2, as shown.

R2# show ipv6 route eigrp | begin 2001

D2001:DB8:198:51:100::/80 [90/16000]

via FE80::23:3, GigabitEthernet0/0/1

D2001:DB8:ACAD:3::/64 [90/10880]

via FE80::23:3, GigabitEthernet0/0/1

D2001:DB8:ACAD:32::/64 [90/15360]

via FE80::23:3, GigabitEthernet0/0/1

The output above confirms R2 has learned EIGRP routes for IPv4 and IPv6.

Part 4:Configure Redistribution from OSPFv3 to EIGRP

Recall that every protocol provides a seed metric at the time of redistribution. By default, when source protocols, such as, OSPF, RIP, and IS-IS, are redistributed into EIGRP, they are given an administrative distance of 170 and a seed metric of infinity. This prevents the installation of the redistributed routes into the EIGRP topology table. The seed metric can be set using the redistribute or default-metric command. Additionally, when using a route map, the seed metric can be configured using the set metric option.

For IPv4, you will set the seed metric using the redistribute command and the default-metric command.

Step 1:Redistribute OSPFv3 into EIGRP for IPv4.

In this step were going to the destination EIGRP AS 64512 to perform redistribution. Since EIGRP is using named mode the redistribute command is entered in the address family topology configuration mode, as shown.

R2(config)# router eigrp CISCO

R2(config-router)# address-family ipv4 autonomous-system 64512

R2(config-router–af)# topology base

R2(config-router-af-topology)# redistribute ospfv3 1 metric 1000000 10 255 1 1500

R2(config-router-af-topology)# end

close configuration window

Step 2:On D2, verify redistribution of OSPFv3.

Issue the show ip route eigrp on D2 to see the external EIGRP routes from OSPFv3.

Open configuration window

D2# show ip route eigrp | begin Gateway

Gateway of last resort is 10.1.32.3 to network 0.0.0.0

D*EX0.0.0.0/0 [170/66560] via 10.1.32.3, 00:03:59, GigabitEthernet1/0/11

D10.3.3.0/24 [90/10880] via 10.1.32.3, 21:20:07, GigabitEthernet1/0/11

close configuration window

Notice the gateway of last resort has been set and D2 has learned four external EIGRP routes which originated from OSPFv3. The OSPFv3 routes are imported into EIGRP as external, D EX routes with an administrative distance of 170, which are higher than the internal EIGRP routes of 90.

Step 3:Redistribute OSPFv3 into EIGRP for IPv6.

Again, go to the destination protocol to perform redistribution. In this example you will set the seed metric using the default-metric command. Both commands are configured in the IPv6 address-family topology base, as shown.

Open configuration window

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

R2(config-router-af–topology)# redistribute ospf 1

Note: Do not leave AF topology configuration mode.

In the example above, the seed metric was set using the default-metric command.

Notice the include-connected option was not configured using the redistribute ospf 1 command. The include-connected command must be set for OSPFv3 IPv6 connected interface on R2, in our example, 2001:db8:acad:12::/64 to be redistributed into EIGRP. With IPv4, connected interfaces are automatically advertised into the routing protocol for connected interfaces the source protocol is advertising. For IPv6, the administrator decides whether the connected subnets are included into redistribution.

Also notice under the EIGRP IPv6 address family, it is not possible to specify OSPFv3 as the source protocol for redistribution. Instead the ospf keyword automatically assumes OSPFv3 since the command is entered under the IPv6 address family.

Step 4:On D2 Verify OSPFv3 redistribution for IPv6.

Issue the command to view the IPv6 routing table for EIGRP.

Open configuration window

D2# show ipv6 route eigrp | begin EX::

EX::/0 [170/66560], tag 1

via FE80::32:3, GigabitEthernet1/0/11

EX2001:DB8:ACAD:1::/64 [170/66560]

via FE80::32:3, GigabitEthernet1/0/11

D2001:DB8:ACAD:3::/64 [90/10880]

via FE80::32:3, GigabitEthernet1/0/11

EX2001:DB8:ACAD:11::/64 [170/66560]

via FE80::32:3, GigabitEthernet1/0/11

D2001:DB8:ACAD:23::/64 [90/15360]

via FE80::32:3, GigabitEthernet1/0/11

close configuration window

Notice the three highlighted external routes. The 2001:db8:acad:12::/64 prefix was not redistributed because of the missing include-connected keyword.

Step 5:Redistribute OSPFv3 connected routes into EIGRP for IPv6.

1. From the EIGRP IPv6 address family topology configuration mode configure redistribution with the same command as the previous step, but this time add include-connected as shown.

R2(config-router-af–topology)# redistribute ospf 1 include-connected

R2(config-router-af-topology)# end

Close configuration window

2. On D2, verify the IPv6 prefixes are being redistributed as before, as well as the connected prefix, which is included and highlighted in the routing table.

Open configuration window

D2# show ipv6 route eigrp | begin EX::

EX::/0 [170/66560], tag 1

Part 5:Configure Redistribution from EIGRP for IPv4 into OSPFv3

In this part, you will perform EIGRP for IPv4 redistribution into OSPFv3.

Note: When redistributing into OSPFv2, you must include the subnets keyword. The keyword subnets is required for classless networks to be advertised. If omitted only classful networks using a classful mask will be redistributed.

Step 1:On R2, redistribute EIGRP into OSPFv3.

The redistribute command is always performed on the destination protocol. Start by accessing the OSPFv3 address family for IPv4. Then redistribute the source protocol, EIGRP 64512 into the destination protocol, as shown.

Open configuration window

R2(config)# router ospfv3 1

R2(config-router)# address-family ipv4 unicast

R2(config-router–af)# redistribute eigrp 64512

Note: Do not leave AF configuration mode.

Step 2:Verify redistribution on D1.

Issue the show ip route ospfv3 on D1 to see the external OSPF routes from EIGRP.

Open configuration window

D1# show ip route ospfv3 | begin Gateway

close configuration window

Notice the highlighted external E2 OSPF routes. By default, external LSAs appear in the routing table marked as E2 with an external cost of 20.

Step 3:Redistribute EIGRP into OSPFv3 using a Type 1.

From the address family configuration mode, modify the redistribute command configured in Step 1 to specify an external type 1.

R2(config-router-af)# redistribute eigrp 64512 metric-type ?

1Set OSPF External Type 1 metrics

2Set OSPF External Type 2 metrics

R2(config-router-af)# redistribute eigrp 64512 metric-type 1

R2(config-router-af)# exit

close configuration window

Step 4:Verify redistribution again on D1.

1. Issue the show ip route ospfv3 on D1 to see the external OSPF routes.

Open configuration window

D1# show ip route ospfv3 | begin Gateway

Gateway of last resort is 0.0.0.0 to network 0.0.0.0

10.0.0.0/8 is variably subnetted, 7 subnets, 2 masks

O IA10.1.1.0/24 [110/2] via 10.1.11.1, 03:10:29, GigabitEthernet1/0/11

O IA10.1.12.0/24 [110/2] via 10.1.11.1, 1d02h, GigabitEthernet1/0/11

O E110.1.23.0/24 [110/22] via 10.1.11.1, 00:10:11, GigabitEthernet1/0/11

O E110.1.32.0/24 [110/22] via 10.1.11.1, 00:10:11, GigabitEthernet1/0/11

O E110.3.3.0/24 [110/22] via 10.1.11.1, 00:10:11, GigabitEthernet1/0/11

198.51.100.0/25 is subnetted, 1 subnets

O E1198.51.100.0 [110/22] via 10.1.11.1, 00:10:11, GigabitEthernet1/0/11

Notice the highlighted external E1 OSPF routes. These E1 routes have a cost of 22 which includes the default cost of 20 plus the internal cost of 2.

Close configuration window

2. From D2 ping the Loopback address on D1 using Loopback address of D2. The ping should be successful. This verifies successful two-way redistribution on R2 and end-to-end connectivity for IPv4.

Open configuration window

D2# ping 209.165.201.1 source loopback 0

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 209.165.201.1, timeout is 2 seconds:

Packet sent with a source address of 198.51.100.1

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 2/2/3 ms

Close configuration window

Step 5:Configure redistribution of EIGRP for IPv6 routes into OSPFv3 using a route map.

Next, you will redistribute EIGRP for IPv6 routes into OSPFv3 using a route map to set the external LSA to a metric type 1, or E1.

1. First, you create a route map name E2O with a permit statement using a sequence number of 10. Because you are not going to use the match command, the default action is to match all. Then you set the metric type to an E1, or m, as shown.

Open configuration window

R2(config)# route-map E2O permit 10

R2(config-route-map)# set metric-type type-1

R2(config-route-map)# exit

2. Next, you access the OSPFv3 IPv6 address family. Then you issue the redistribute command and specify the route map name. Ensure to add the include-connected after the route map name, as shown.

R2(config)# router ospfv3 1

R2(config-router)# address-family ipv6

R2(config-router-af)# redistribute eigrp 64512 route-map E2O include-connected

R2(config-router-af)# exit

The route map E2O will match all redistributed routes, including connected interfaces advertised in EIGRP 64512.

Close configuration window

Step 6:On D1 verify that routes from EIGRP for IPv6 are imported into OSPFv3 with the external metric type 1.

1. Issue the show ipv6 route ospf on D1 to see the external EIGRP routes. Notice the highlighted external E1 OSPF routes.

Open configuration window

D1# show ipv6 route ospf

close configuration window

2. From D2, ping the Loopback address on D1 using Loopback address of D2. The ping should be successful. This verifies full successful two-way redistribution on R2 and end-to-end connectivity for IPv6.

Open configuration window

D2# ping 2001:db8:209:165:201::1 source loopback 0

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 2001:DB8:209:165:201::1, timeout is 2 seconds:

Packet sent with a source address of 2001:DB8:198:51:100::1

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 2/4/9 ms

Reflection Questions

1. What is the difference between an external OSPF E2 and E1?

Type your answers here.

OSPF metric type E2 is the default, if not specified. An E2 has an external cost of 20. Metric type 1 or E1 calculates the cost by adding the external cost to the internal cost for each link the packet traverses. Use an E1 when there are multiple ASBRs advertising an external route to the same AS.

2. What are three ways to set a seed metric during redistribution?

Type your answers here.

Using the redistribute command, using the default-metric command and using a route map with the set metric command

3. What is the default action in a route map if you do not include the match command?

Type your answers here.

The default action is to match any

Router Interface Summary Table

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.
