1
00:00:09,320 --> 00:00:13,220
Son on router 2, I don't know what the password is once again.

2
00:00:15,310 --> 00:00:21,250
I need physical access to the device, so I'm going to turn the power off and turn it back on again

3
00:00:22,090 --> 00:00:24,160
and press control C to break.

4
00:00:25,280 --> 00:00:31,150
I'm in ROM monitor again, question mark enter shows me options, help does something similar.

5
00:00:32,580 --> 00:00:40,290
Reg allows me to set the configuration register 2142  is what I'm going to set it to and then reset

6
00:00:40,290 --> 00:00:42,780
allows me to get the router to reboot.

7
00:00:43,790 --> 00:00:53,150
Router is now rebooting and will hopefully reboot without a startup configuration applied, in other words,

8
00:00:53,180 --> 00:00:59,920
the startup configuration is still there, but as you can see here is not applied to the running configuration.

9
00:01:00,620 --> 00:01:04,760
I'm going to bypass the initial configuration dialog, again

10
00:01:05,030 --> 00:01:12,980
I can go to enable or privilege mode and use commands such as show run to see a default configuration.

11
00:01:13,580 --> 00:01:22,160
Make sure that you go to privilege mode before you copy the startup configuration.

12
00:01:22,940 --> 00:01:26,720
Notice the startup configuration has the secret password set.

13
00:01:27,350 --> 00:01:29,690
We don't know what that password is.

14
00:01:30,290 --> 00:01:32,840
We can see some other configuration on the router.

15
00:01:33,440 --> 00:01:43,910
But note, I went from user mode to privilege or enable mode and now I can copy the startup configuration

16
00:01:44,270 --> 00:01:50,870
to the running configuration and apply it without knowing what the password is.

17
00:01:51,620 --> 00:01:54,530
So Show Run now shows us that password

18
00:01:57,360 --> 00:02:01,830
and shows us the configuration of interfaces and EIGRP.

19
00:02:04,110 --> 00:02:13,740
I still don't know what the secret password is, but I can now simply type enable secret Cisco to override

20
00:02:14,160 --> 00:02:15,510
the secret password.

21
00:02:16,850 --> 00:02:24,830
I'll save the configuration, what I still need to do, however, is enable interfaces that's not done

22
00:02:24,830 --> 00:02:25,580
by default.

23
00:02:26,240 --> 00:02:30,590
So no, shut the various interfaces on the router.

24
00:02:33,710 --> 00:02:37,430
I don't actually need to no shut gigabit 001 down.

25
00:02:37,910 --> 00:02:40,940
That's not part of the lab, so I'll shut that again.

26
00:02:42,290 --> 00:02:44,810
Show IP interface brief, 

27
00:02:46,620 --> 00:02:52,440
there are our device IP addresses, interfaces are up show IP protocols.

28
00:02:55,350 --> 00:03:01,170
We are running EIGRP, show IP EIGRP neighbor, 

29
00:03:01,530 --> 00:03:04,580
we've got a neighbor relationship to router 1.

30
00:03:05,340 --> 00:03:08,130
Let's see if we can ping the loopback of router 1.

31
00:03:09,730 --> 00:03:16,990
So on router 1, show IP interface brief, IP address is 1.1.1.1, so on router 2

32
00:03:17,980 --> 00:03:18,700
ping 1.

33
00:03:18,800 --> 00:03:20,830
1.1.1 that works.

34
00:03:22,210 --> 00:03:29,590
Router 1 can ping the loopback of router 2, it's good idea to save your configuration often again

35
00:03:29,590 --> 00:03:32,050
for the exam, you're going to do it this way.

36
00:03:32,750 --> 00:03:41,320
WR may not work in the exam, so let's verify that when we exit and log back in, we can log in with

37
00:03:41,320 --> 00:03:45,750
the password of Cisco and we are able to do that in this example.

38
00:03:46,660 --> 00:03:47,650
So that works.

39
00:03:49,380 --> 00:03:57,120
Now, again, just because we've saved the configuration of the router doesn't mean that things are going

40
00:03:57,120 --> 00:03:57,680
to work.

41
00:03:58,290 --> 00:04:06,090
I need to set the configuration register to 0x2102.

42
00:04:07,640 --> 00:04:09,820
So that's now done, again

43
00:04:09,980 --> 00:04:15,330
you don't need to save the configuration once you've set the configuration register

44
00:04:15,860 --> 00:04:17,350
that's a separate parameter.

45
00:04:17,990 --> 00:04:24,890
So I've reset the enable password of router 1 to Cisco and  the secret password of router 2 to Cisco.

46
00:04:25,520 --> 00:04:29,570
Now I need to reset the password of the switch.
