Topology

Tasks
OSPF is partially configured. Complete the OSPF configurations to achieve these goals:
1. Configure OSPF on router R1 according to the topology so that all networks are advertised. Do not use the network statement under the "router ospf" configuration section to accomplish this task.
2. Configure a single command on the ABR routers to ensure only one summary route is advertised to area 0.
