CCNP Lab 029: OSPF Multi-Technology Lab

Lab Objective:

The focus of this lab is to understand OSPF implementation and configuration in Cisco IOS routers. Additional technologies tested include authentication, metrics and .

Lab Topology:

The lab network topology is illustrated below:

department629

 

IMPORTANT NOTE

If you are using the www.howtonetwork.net racks, please bring up the LAN interfaces connected to the routers by issuing the no shutdown command on the connected switches. If you are using a home lab with no
Switches, you can bring up the LAN interfaces using the following configurations on your routers:

interface fastethernet 0/0
no keepalive
loopback
no shutdown

Alternately, you can simply connect the interfaces to a hub or switch if you have one available in your own lab.

 

Task 1

Configure hostnames and IP addressing on all routers as illustrated in the network topology.

Task 2

Using legacy network x.x.x.x y.y.y.y area <area> OSPF configuration commands, configure OSPF area 0 as illustrated in the topology. Ensure that no OSPF Hellos are sent out of the LAN interfaces on R2 and R3. Verify your configuration using the appropriate commands.

Task 3

Using legacy network x.x.x.x y.y.y.y area <area> OSPF configuration commands, configure OSPF area 2 as illustrated in the topology. This area should not allow any inter-area LSAs (except for the default route) or any external LSAs.

Additionally, the router should not send log messages when Type 6 LSAs are received. Ensure that the default route shows up in the routing table of R4 with a route metric of 222. You are NOT allowed to modify any interface bandwidth or cost values to complete this task. Ensure that no OSPF packets are sent out of the LAN interface on R4. Verify your configuration using the appropriate commands.

Task 4

Using legacy network x.x.x.x y.y.y.y area <area> OSPF configuration commands, configure OSPF area 3 as illustrated in the topology. Authenticate OSPF messages between R1 and R2 using the plain text password ‘CCNP’. Authentication should be performed only at the interface level. Verify your configuration using the appropriate commands.

Task 5

Using legacy network x.x.x.x y.y.y.y area <area> OSPF configuration commands, configure OSPF area 1 as illustrated in the topology. Configure MD5 authentication for area 1 using the password ‘CCNP’. Verify your configuration.

Task 6

Using legacy network x.x.x.x y.y.y.y area <area> OSPF configuration commands, configure OSPF for area 5 as illustrated in the topology. In the future, an additional router will be added to this segment. This router will be redistributing external routes from business partner routers. Configure area 5 so that these routes can be imported into OSPF as Type 7 routes. No inter-area or Type 5 LSAs should be allowed into this area. Finally, ensure that all other routers in the network are able to ping R1s LAN (and any future area 5 subnets).Verify your configuration using the appropriate commands.

Task 7

Configure R1 so that the virtual link going to R2 is assigned a cost of 2 and the virtual link going to R3 is assigned a cost of 3. Verify your configuration.

Task 8

In the future, the FastEthernet link on R2 will be replaced with a GigabitEthernet link. Configure R2 so that OSPF accurately calculates route metrics when this is performed.
