Repeat the scenario from Day 10 (two routers directly connected, Loopback interface on each of them) but instead of configuring RIP and advertising the physical and Loopback interfaces, do this using OSPF Area 0:
- Assign an IPv4 address to the directly connected interfaces (10.10.10.1/24 and 10.10.10.2/24)
- Test direct connectivity using ping
- Configure a Loopback interface on each router and assign addresses from two different ranges (11.11.11.1/32 and 12.12.12.2/32)
- Configure standard OSPF process 1 and advertise all the local networks in Area 0. Also, configure a router id for each device:
R1:
router ospf 1
router-id 1.1.1.1
network 10.10.10.0 0.0.0.255 area 0
network 11.11.11.0 0.0.0.0 area 0
R2:
router ospf 1
router-id 2.2.2.2
network 10.10.10.0 0.0.0.255 area 0
network 12.12.12.0 0.0.0.0 area 0
- Ping R2 Loopback from R1 to test connectivity
- Issue a show ip route command to verify that routes are being received via OSPF
- Issue a show ip protocols command to verify that OSPF is configured and active on the devices
- Verify the interface OSPF-specific parameters: show ip ospf interface and show ip ospf interface brief
- Change the OSPF Hello and Dead timers on both routers (directly connected interfaces): ip ospf hello and ip ospf dead
- Issue a show ip ospf 1 command to see the routing process parameters
- Repeat the lab but this time advertise the networks in OSPF using the ip ospf 1 area 0 interface specific command instead of the network command under router OSPF
