Lab 6: OSPF

Task

1. Configure IP Address as per given in topology.

2. Configure OSPF According to the topology and provide Router-ID as Router Name (like 1.1.1.1 for

R1).

3. Communicate OSPF Area 100 to OSPF Area 0.

4. Make sure all the loopback addresses are manual summarize in OSPF Areas.

5. Make sure R10 loopback not advertise in area 0.
