1. Cable the lab as shown above.
- From the "Router A"
console
- Configure OSPF routing in Area 0
- From the "Router B"
console
2. To configure the interfaces and
setup multi-area OSPF issue the following commands:
- router-b(config)#interface
loopback 0
- router-b(config-if)#ip
address 2.0.202.206 255.255.255.0
- router-b(config-if)#interface
fastethernet 0/0
- router-b(config-if)#ip
address 206.202.0.2 255.255.255.0
- router-b(config-if)#no
shutdown
- router-b(config-if)#interface
serial 0/0
- router-b(config-if)#ip
address 206.202.1.1 255.255.255.0
- router-b(config-if)#clockrate
56000
- router-b(config-if)#router
ospf 1
- router-b(config-router)#network
206.202.0.0 0.0.0.255 area 0
- router-b(config-router)#network
206.202.1.0 0.0.0.255 area 1
- router-b(config-router)#^Z
3. Enter show
ip ospf and show
ip ospf border-routers.
Report your findings below:



From the "Router C" console
4. Issue the following commands:
- router-c(config)#interface
loopback 0
- router-c(config-if)#ip
address 1.2.202.206 255.255.255.0
- router-c(config-if)#interface
fastethernet 0/0
- router-c(config-if)#ip
address 206.202.2.1 255.255.255.0
- router-c(config-if)#no
shutdown
- router-c(config-if)#interface
serial 0/0
- router-c(config-if)#ip
address 206.202.1.2 255.255.255.0
- router-c(config-if)#router
ospf 1
- router-c(config-router)#network
206.202.1.0 0.0.0.255 area 1
- router-c(config-router)#network
206.202.2.0 0.0.0.255 area 1
- router-c(config-router)#^Z
5. Enter show
ip ospf interface
Is the OSPF protocol turned on the
correct interfaces that you defined?

- From the "Router D"
console
- Configure OSPF routing in Area 1
only.
- After you have configured
"Router D" go back to each router and verify that
ospf is turned on and advertising the correct networks. Ping
all interfaces.
6. Enter show
ip ospf neighbor and report
your findings below:

7. Enter show
ip ospf border-router and show
ip route
What information did the router
respond with?


8. Enter
show ip ospf interface and debug
ip ospf events
What routers are sending hellos and
from what area? Why?


9. Enter undebug
