1
00:00:00,390 --> 00:00:01,780
Rodolfo is easy.

2
00:00:01,800 --> 00:00:07,050
We need to enable OSPF on all interfaces with a single network command.

3
00:00:09,600 --> 00:00:11,460
So this is the easiest one of all.

4
00:00:11,490 --> 00:00:20,460
Show IP interface brief shows us our interfaces, but we're going to simply enable OSPF on all interfaces

5
00:00:20,610 --> 00:00:31,800
by using the command router OSPF process ID one network and here we can just specify zeros as the network

6
00:00:31,890 --> 00:00:38,040
and a wildcard mask of all ones, which implies anything.

7
00:00:38,520 --> 00:00:44,340
So we're going to enable OSPF on all interfaces with that single command.

8
00:00:45,000 --> 00:00:48,600
So show run notice.

9
00:00:48,600 --> 00:00:50,970
Our relationship has already come up.

10
00:00:52,750 --> 00:00:55,420
That's our configuration show IP.

11
00:00:55,450 --> 00:01:00,900
OSPF neighbor shows us that we have a neighbor relationship to router three show IP.

12
00:01:00,910 --> 00:01:08,230
OSPF Interface shows us that we've got OSPF enabled on gigabit or zero zero as well as the loopback

13
00:01:08,230 --> 00:01:09,190
interface.

14
00:01:09,790 --> 00:01:17,260
So this is an easy way to configure OSPF, but you need to be careful with doing it this way because

15
00:01:17,260 --> 00:01:24,370
any new interfaces added to the router will result in OSPF being enabled on those interfaces.

16
00:01:25,570 --> 00:01:26,910
Show IP route.

17
00:01:26,920 --> 00:01:29,620
We can see routes in the routing table.

18
00:01:30,400 --> 00:01:38,230
We can ping router one, we can ping router two, we can ping router three.

19
00:01:38,650 --> 00:01:46,330
So it looks like we've completed the configuration of the network.

20
00:01:47,210 --> 00:01:54,140
And looking at the tasks we have, let's do a few more tests so I can write a one ping.

21
00:01:54,140 --> 00:01:56,270
The loopback of router four.

22
00:01:56,300 --> 00:01:57,500
Yes, it can.

23
00:01:57,500 --> 00:01:59,030
Loopback of router three.

24
00:01:59,180 --> 00:02:00,170
Yes.

25
00:02:00,440 --> 00:02:02,510
Loopback of router two.

26
00:02:02,540 --> 00:02:03,380
Yes.

27
00:02:03,620 --> 00:02:05,660
Can we trace to router four?

28
00:02:05,660 --> 00:02:06,830
Yes, we can.

29
00:02:06,950 --> 00:02:10,970
And you can see traffic goes via router two and router three.

30
00:02:11,090 --> 00:02:12,770
So everything looks good.

31
00:02:13,480 --> 00:02:15,040
So this looks good.

32
00:02:15,070 --> 00:02:17,440
We've successfully completed the slab.

33
00:02:17,710 --> 00:02:18,740
How did you get on?

34
00:02:18,760 --> 00:02:24,280
Were you able to configure OSPF in a single area per the lab instructions?

35
00:02:24,670 --> 00:02:28,180
Make sure that you learn about OSPF for your exam.
