Rodolfo is easy.
We need to enable OSPF on all interfaces with a single network command.
So this is the easiest one of all.
Show IP interface brief shows us our interfaces, but we're going to simply enable OSPF on all interfaces
by using the command router OSPF process ID one network and here we can just specify zeros as the network
and a wildcard mask of all ones, which implies anything.
So we're going to enable OSPF on all interfaces with that single command.
So show run notice.
Our relationship has already come up.
That's our configuration show IP.
OSPF neighbor shows us that we have a neighbor relationship to router three show IP.
OSPF Interface shows us that we've got OSPF enabled on gigabit or zero zero as well as the loopback
interface.
So this is an easy way to configure OSPF, but you need to be careful with doing it this way because
any new interfaces added to the router will result in OSPF being enabled on those interfaces.
Show IP route.
We can see routes in the routing table.
We can ping router one, we can ping router two, we can ping router three.
So it looks like we've completed the configuration of the network.
And looking at the tasks we have, let's do a few more tests so I can write a one ping.
The loopback of router four.
Yes, it can.
Loopback of router three.
Yes.
Loopback of router two.
Yes.
Can we trace to router four?
Yes, we can.
And you can see traffic goes via router two and router three.
So everything looks good.
So this looks good.
We've successfully completed the slab.
How did you get on?
Were you able to configure OSPF in a single area per the lab instructions?
Make sure that you learn about OSPF for your exam.
