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.

You are not required to configure the following:
- The network switches
- The network hosts
- The College Intranet Server

Host Address Table
The addresses of the PC and server hosts are provided for connectivity testing purposes. All addressing is preconfigured.
Instructions
Step1: Configure default static routes on the Administration router.
Configure IPv4 and IPv6 default static routes on Administration. Use the exit interface value in your configuration.
Step 2: Configure single-area OSPFv2
On the Administration, Science, and Technology routers, configure single-area OSPFv2 in Area 0.
a. Use a process ID of 10 for all OSPFv2 processes.
b. Activate routing for the appropriate networks. Use inverse masks that specify only addresses within the networks.
c. Specify a bandwidth value that matches the clock speed of the interfaces of Administration for interfaces of alldevices that are configured in Area 0.
d. Set the router IDs as follows:
Administration: 10.20.0.0
Science: 10.0.0.0
Technology: 20.0.0.0
Step 3: Configure single-area OSPFv3.
On the Administration, Science, and Technology routers configure single-area OSPFv3 in Area 0.

Configure the routers that have all interfaces in Areas 10 and 20 with OSPFv2.
a. Use a process ID of 10 for all OSPF processes.
b. Activate routing for the appropriate networks. Use inverse masks that specify only addresses within the networks. After this step is completed, hosts on all LANs should be able to communicate with each other over IPv4.

Electronics: 20.2.2.2
Step 6: Customize OSPFv2.
Customize OSPFv2 operation as follows:
a. For the multiaccess network connected between the Bioand Physics routers, configure priorities so that Bio will become the DR and Physics will be the BDR. Use priority values of 255 and 200.
b. Configure the interfaces on all routers that are attached to LANs with hosts to notsend OSPFv2 traffic into the LAN.
c. Enable all routers to automatically and accurately calculate costs for routes that include 1Gbps Ethernet networks by changing the reference bandwidth.
d. Configure OSPFv2 so that the default routes that are configured on Administrationare automatically distributed to all routers in the network.
e. Adjust the OSPFv2 timers on the Ethernet link between Bioand Physics as follows:
Hello: 5 seconds
Dead: 20 seconds
Step 7: Customize OSPFv3.
Customize OSPFv3 operation as follows:
a. For the multiaccess network connected between the Bioand Physics routers configure priorities so that Bio will become the DR and Physics will be the BDR. Use priority values of 255 and 200.
