1
00:00:16,360 --> 00:00:17,620
In this lab.

2
00:00:17,620 --> 00:00:23,350
We've been told to configure OSPF in multiple areas as shown in the diagram.

3
00:00:23,890 --> 00:00:32,380
In the diagram we have area zero, area one and Area two, and we've been told to configure OSPF as

4
00:00:32,380 --> 00:00:37,150
follows We need to use OSPF process ID one on router one.

5
00:00:37,150 --> 00:00:42,580
We need to enable OSPF using the network command with an exact IP match.

6
00:00:43,330 --> 00:00:44,160
On rather to.

7
00:00:44,170 --> 00:00:49,000
We need to enable OSPF using the network command based on subnet mask.

8
00:00:49,860 --> 00:00:56,430
On Brother three We need to enable OSPF using the interface command and on router four we need to enable

9
00:00:56,430 --> 00:01:01,500
OSPF on all interfaces using a single network command.

10
00:01:02,530 --> 00:01:15,340
Now in this topology router two has gigabit 000 in area one and gigabit is 001 in area zero.

11
00:01:16,180 --> 00:01:19,990
The Loopback interface is not just shown in the exam.

12
00:01:19,990 --> 00:01:26,860
It should be clear which area the loopback and every other interface should go into.

13
00:01:27,710 --> 00:01:28,940
In this example.

14
00:01:28,940 --> 00:01:33,860
Just assume that loop backs on router two and router three.

15
00:01:33,890 --> 00:01:35,660
Go in area zero.

16
00:01:36,750 --> 00:01:37,770
On Rata one.

17
00:01:38,100 --> 00:01:47,910
The entire Rada belongs in area one and on writer for the entire Rada has interfaces in area two, so

18
00:01:47,910 --> 00:01:49,440
that's easy to understand.

19
00:01:49,500 --> 00:01:55,710
But on Rada three and Rada to put your loopback interfaces into Area zero.

20
00:01:56,550 --> 00:01:59,370
So can you complete this lab?

21
00:01:59,400 --> 00:02:05,610
Download the packet, trace a file and see if you can configure the network yourself.

22
00:02:05,760 --> 00:02:12,960
In the next video I'm going to show you how to configure OSPF per these instructions and I'll also show

23
00:02:12,960 --> 00:02:14,340
you some tips and tricks.
