Step 1: Cable the network.
Step 2: Configure basic settings for each router.
  a. Configure host names as shown in the topology.
  b. Configure interface IP addresses as shown in the IP Addressing Table.
  c. Configure a clock rate for routers with a DCE serial cable attached to their serial interface. R1 is shown here as an example.
     R1(config)# interface S0/0/0
     R1(config-if)# clock rate 64000
  d. To prevent the router from attempting to translate incorrectly entered commands as though they were host names, disable DNS lookup. R1 is shown here as an example.
     R1(config)#no ip domain-lookup

Step 3: Configure OSPF routing on the routers.
     a. Use the router ospf command in global configuration mode to enable OSPF on R1.
        R1(config)# router ospf 1
     b. Configure the network statements for the networks on R1. Use an area ID of 0.
        R1(config-router)# network 192.168.1.0 0.0.0.255 area 0
        R1(config-router)# network 10.1.1.0 0.0.0.3 area 0
     c. Configure OSPF on R2 and R3passive-interface g0/1.
     d. Issue the passive-interface command to change the G0/1 interface on R1 and R3 to passive.
         R1(config)# router ospf 1
         R1(config-router)# passive-interface g0/1
         R3(config)# router ospf 1
         R3(config-router)# passive-interface g0/1

Step 4: Verify OSPF neighbors and routing information.
     a. Issue the show ip ospf neighbor command to verify that each router lists the other routers in the network as neighbors.
        R1# show ip ospf neighbor
     b. Issue the show ip route command to verify that all networks display in the routing table on all routers
        R1# show ip route
Step 5: Configure PC host IP settings.
        Configure a static IP address, subnet mask, and default gateway for PC-A and PC-C as shown in the IP Addressing Table.
Step 6: Verify connectivity between PC-A and PC-C.
Step 7: Save the basic running configuration for each router.
