OSPF “Magic” Exercise
• We will use a “quick and dirty” configuration to make OSPF work with minimal configuration.
• DO NOT do this on your production network.
• Production networks should use slightly more complex, but safer, techniques.

Step 1:
• Ensure that your PC has a static default route to the router
• $ netstat -rn -f inet
• If there is no static route entry,
• $ route add default routerEth1IP

• Delete all static routes (including default) on the Cisco Router
# sh ip route
For all static routes displayed above …
# conf t
# no ip route x.x.x.x y.y.y.y z.z.z.z
# .
# ^Z
# sh ip route

• Perform the MAGIC
# conf t
# router ospf 1
# network 0.0.0.0 255.255.255.255 area 0
# redistribute connected subnets
# ^Z
# sh ip route
