Assessment button in the browser window to submit your work. 3. Click the Submit Assessment button Introduction In this practice skills assessment, you will configure the Famous University network with OSPF routing. The network is configured with both IPv4 and IPv6 on all devices. This will allow you to implement routing in both OSPFv2 and OSPFv3. In addition, you will configure both versions of OSPF in multiple areas. For a full list of tasks, see below. You are not required to configure the following:    

Instructions Step1: Configure default static routes on the Administration router. Administration . Use the exit interface value Configure IPv4 and IPv6 default static routes on Administration. in your configuration. Step 2: Configure single-area OSPFv2 On the Administration, Administration , Science, Science , and Technology routers, Technology routers, configure single-area OSPFv2 in Area 0. 0. 1. Use a process ID of 10 for all all OSPFv2 OSPFv2 processes. 2. Activate routing for the appropriate networks. Use inverse masks that specify only addresses only addresses within the networks. 3. Specify a bandwidth value that matches the clock speed of the interfaces of Administration for Administration for interfaces of all alldevices devices that are configured in Area 0. 4. Set the router IDs as follows:

Administration: 10.20.0.0 Science: 10.0.0.0 Technology: 20.0.0.0 Technology: 20.0.0.0

Step 3: Configure single-area OSPFv3. On the Administration the Administration,, Science, Science , and Technology routers Technology routers configure single-area OSPFv3 in Area 0. 0. 1. Use a process ID of 10 for all all OSPFv3 OSPFv3 processes. 2. Activate routing for the appropriate networks. 3. Set the router IDs as follows: Administration: 10.20.0.0 Science: 10.0.0.0

Technology: 20.0.0.0 Step 4: Configure OSPFv2 in multiple areas. Configure the routers that have all all interfaces interfaces in Areas 10 and 20 with OSPFv2. 1. Use a process ID of 10 10 for for all OSPF processes. 2. Activate routing for the appropriate networks. Use inverse masks that specify only addresses only addresses within the networks. After this step is completed, hosts on all LANs should be able to communicate with each other over IPv4. 3. Set the router IDs as follows: Bio: 10.1.1.1 Bio: 10.1.1.1 Physics: 10.2.2.2 CompSci: 20.1.1.1 Electronics: 20.2.2.2

Step 5: Configure OSPFv3 in multiple areas. Configure the routers that have all all interfaces interfaces in Areas 10 and 20 with OSPFv3. 1. Enable the routers to route IPv6. 2. Use a process ID of 10 10 for for all OSPF processes. 3. Activate routing for the appropriate networks. After this step is completed, hosts on all LANs should be able to communicate with each other over IPv6. 4. Set the router IDs as follows: Bio: 10.1.1.1 Bio: 10.1.1.1 Physics: 10.2.2.2 CompSci: 20.1.1.1 Electronics: 20.2.2.2 Step 6: Customize OSPFv2. Customize OSPFv2 operation as follows:

1. For the multiaccess network connected between the Bio and Bio and Physics routers, Physics routers, Bio will become the DR and Physics will Physics will be the BDR. Use configure priorities so that Bio will priority values of 255 of 255 and and 200 200.. not send 2. Configure the interfaces on all routers that are attached to LANs with hosts to not send OSPFv2 traffic into the LAN.

3. Enable all routers to automatically and accurately calculate costs for routes that include 1Gbps Ethernet networks by changing the reference bandwidth. Administration are 4. Configure OSPFv2 so that the default routes that are configured on Administration are automatically distributed to all routers in the network. 5. Adjust the OSPFv2 timers on the Ethernet link between Bio and Bio and Physics as Physics as follows: Hello: 5 seconds Dead: 20 20 seconds seconds Step 7: Customize OSPFv3. Customize OSPFv3 operation as follows:

1. For the multiaccess network connected between the Bio and Bio and Physics routers Physics routers configure 2. 3. 4. 5.

priorities so that Bio will Bio will become the DR and Physics will Physics will be the BDR. Use priority values of 255 255 and and 200 200.. Configure the interfaces on all routers that are attached to LANs with hosts to not send not send OSPFv3 traffic into the LAN. Enable all routers to automatically and accurately calculate costs for routes that include 1Gbps Ethernet networks by changing the reference bandwidth. Configure OSPFv3 so that the default routes that are configured on Administration are Administration are automatically distributed to all routers in the network. Explicitly configure the OSPFv3 timers on the Ethernet link Bio and Physics as Physics as follows: between Bio and Hello: 5 seconds Dead: 20 20 seconds seconds
