If you want more labs like these, I highly\n
7
00:00:30,359 --> 00:00:34,420
the CCNA, click the link in the video description\n
8
00:00:34,420 --> 00:00:39,179
It’s a network simulator like packet tracer,\n
9
00:00:39,179 --> 00:00:44,119
of these guided labs to not only help you\n
10
00:00:44,119 --> 00:00:46,939
but also deepen your understanding of the\nexam topics.
11
00:00:46,939 --> 00:00:52,719
I used it myself when studying for my certifications,\n
12
00:00:54,299 --> 00:01:00,269
If you want to get your own copy of NetSim,\n
13
00:01:00,270 --> 00:01:03,690
In this lab we will go through the configurations\n
14
00:01:05,519 --> 00:01:12,109
First, in step 1 we will ping an external\n
15
00:01:13,879 --> 00:01:19,649
I’ll do the ping from PC1 first.
16
00:01:28,459 --> 00:01:31,519
Now let’s check PC1’s default gateway.
17
00:01:31,519 --> 00:01:37,369
On a PC you can use this command, IPCONFIG,\n
18
00:01:37,370 --> 00:01:44,210
So, R1’s (*PC1's) default gateway address is 10.0.1.253,\n
19
00:02:00,799 --> 00:02:03,599
So, what’s PC2’s default gateway?
20
00:02:05,978 --> 00:02:09,949
It’s R1, so it’s the same as PC1.
21
00:02:09,949 --> 00:02:12,939
Now, let me do something I didn’t do on\nPC1.
22
00:02:12,939 --> 00:02:16,199
I’ll do a traceroute to 8.8.8.8.
23
00:02:16,199 --> 00:02:21,688
I’ve shown you this once before I think,\n
24
00:02:21,688 --> 00:02:28,568
On PCs the command is ‘tracert’, but be\n
25
00:02:30,718 --> 00:02:40,930
So, TRACERT 8.8.8.8, and you can confirm that\n
26
00:02:40,930 --> 00:02:48,620
8.8.8.8, which is just a loopback interface\non R3, by the way.
27
00:02:48,620 --> 00:02:56,090
Next up in step 2 we are told to configure\n
28
00:02:56,090 --> 00:03:02,058
We should make sure R1 is the active router,\n
29
00:03:10,049 --> 00:03:19,049
CONF T. Remember, FHRPs like HSRP are configured\n
30
00:03:20,419 --> 00:03:25,209
First, let’s enable HSRP version 2.
31
00:03:25,209 --> 00:03:30,560
The command is STANDBY VERSION 2.
32
00:03:30,560 --> 00:03:32,489
Next I’ll configure the virtual IP.
33
00:03:32,489 --> 00:03:38,530
I didn’t mention this in the lecture video,\n
34
00:03:38,530 --> 00:03:43,639
preemption, priority, etc without specifying\nthe group number.
35
00:03:43,639 --> 00:03:48,760
If you do this, the router will automatically\n
36
00:03:48,759 --> 00:03:52,848
The STANDBY VERSION command, however, applies\n
37
00:03:53,949 --> 00:03:58,278
I like to match the group number with the\n
38
00:04:00,628 --> 00:04:05,968
I haven’t done any VLAN configuration on\n
39
00:04:05,968 --> 00:04:09,338
You can use whatever group number you want,\nthough.
40
00:04:09,338 --> 00:04:14,079
First I’ll configure the virtual IP and\n
41
00:04:25,129 --> 00:04:27,569
Finally I’ll enable preemption.
42
00:04:29,120 --> 00:04:34,769
Okay, that’s all for now on R1.
43
00:04:42,470 --> 00:04:48,580
Okay, I’m going to leave it at HSRP version\n
44
00:04:56,329 --> 00:05:00,120
Now the virtual IP, same as on R1.
45
00:05:05,459 --> 00:05:11,239
Now I’m going to click this arrow here in\n
46
00:05:11,240 --> 00:05:16,569
If I return to R2, you can see all of these\n
47
00:05:16,569 --> 00:05:21,910
That’s because both R1 and R2 think they\nare the active router.
48
00:05:23,089 --> 00:05:26,228
It’s because of the version mismatch.
49
00:05:26,228 --> 00:05:31,229
Because there is a version mismatch, they\n
50
00:05:31,230 --> 00:05:34,099
they both claim to be the active router.
51
00:05:34,098 --> 00:05:38,449
To fix this, I’ll configure version 2 here\non R2.
52
00:05:41,449 --> 00:05:44,099
Now I’ll click those arrows again.
53
00:05:55,930 --> 00:06:01,490
And down here you can see that the active\n
54
00:06:01,490 --> 00:06:07,819
So, now that the versions match everything\n
55
00:06:07,819 --> 00:06:14,468
Next up, in step 3 I’ll configure the new\n
56
00:06:17,589 --> 00:06:22,938
Click on ‘config’, then set the default\ngateway here.
57
00:06:25,810 --> 00:06:32,379
‘Config’, and set it to 10.0.1.254.
58
00:06:32,379 --> 00:06:35,789
From here on PC2 I’ll try a ping again.
59
00:06:45,899 --> 00:06:53,508
On PCs the command is ARP -A. There it is,\n10.0.1.254.
60
00:06:53,509 --> 00:07:02,500
Notice the HSRP version 2 virtual MAC address,\n0000 0C9F F001.
61
00:07:02,500 --> 00:07:04,769
Now let me show you another interesting point.
62
00:07:13,089 --> 00:07:20,599
Notice that the first hop address is 10.0.1.253,\n
63
00:07:23,490 --> 00:07:28,499
Even though the virtual IP is configured as\n
64
00:07:28,499 --> 00:07:32,430
using the interface IP address instead of\n
65
00:07:32,430 --> 00:07:38,098
So, traceroute is a useful tool to check that\n
66
00:07:44,788 --> 00:07:49,219
But before that, we must make sure to save\nthe config!
67
00:07:49,220 --> 00:07:55,860
Here on R1 I’ll type END to return to privileged\n
68
00:07:58,079 --> 00:08:02,718
If you forget to save the config, it will\n
69
00:08:03,949 --> 00:08:12,028
To do so, click on the ‘physical’ tab\n
70
00:08:12,028 --> 00:08:17,159
Now I’ll click the arrows to fast forward\n
71
00:08:17,160 --> 00:08:22,659
and now let’s try a ping from PC1.
72
00:08:28,740 --> 00:08:32,158
Okay, the \nping works, so we know R2 must be acting as
73
00:08:32,158 --> 00:08:38,950
the default gateway, R1 is turned off, but\n
74
00:08:42,710 --> 00:08:50,759
Okay, this time the first hop is displayed\n
75
00:08:50,759 --> 00:08:56,720
the virtual IP used as the default gateway\nis .254.
76
00:08:56,720 --> 00:09:00,529
Finally, let’s turn on R1 again.
77
00:09:00,529 --> 00:09:04,059
Go back to R1, and flip the power switch.
78
00:09:04,059 --> 00:09:07,579
I’ll press the arrows again to skip forward.
79
00:09:07,580 --> 00:09:13,850
Now, without checking the CLI of R1 or R2\n
80
00:09:15,850 --> 00:09:20,519
We enabled preemption, so R1 should take back\n
81
00:09:32,370 --> 00:09:38,370
Now traceroute, let’s see if R1’s or R2’s\n
82
00:09:44,659 --> 00:09:53,779
It is R1’s IP address of 10.0.1.253, so\n
83
00:09:56,120 --> 00:10:00,669
Next let’s take a look at a bonus lab in\nBoson NetSim for CCNA.
84
00:10:00,669 --> 00:10:04,729
Okay, here's today's Boson NetSim lab preview.
85
00:10:04,730 --> 00:10:10,389
As I said in the video, FHRP configuration\n
86
00:10:10,389 --> 00:10:13,980
So, it's actually not in NetSim for CCNA.
87
00:10:13,980 --> 00:10:21,259
But I still want to show you an HSRP lab,\n
88
00:10:28,309 --> 00:10:33,519
And FHRP configuration is an exam topic on\n
89
00:10:33,519 --> 00:10:38,500
of labs for FHRPs in NetSim for CCNP.
90
00:10:38,500 --> 00:10:44,659
Starting here, 'Configuring Hot Standby Router\n
91
00:10:45,840 --> 00:10:52,080
So I counted, in total there are 19 labs covering\n
92
00:10:52,080 --> 00:10:56,900
So, all the configuration practice you need\nfor FHRPs.
93
00:10:56,899 --> 00:11:03,139
Okay, the lab I've selected for today is this\n
94
00:11:08,320 --> 00:11:13,350
Pretty simple, we got four switches, access\n
95
00:11:14,629 --> 00:11:19,429
And we're going to configure HSRP on these\nrouters.
96
00:11:19,429 --> 00:11:22,139
These are the commands you need to know.
97
00:11:22,139 --> 00:11:27,539
The STANDBY commands we covered in the lecture,\n
98
00:11:27,539 --> 00:11:30,449
The IP addresses on each device.
99
00:11:30,450 --> 00:11:33,990
And the lab tasks, there are four main tasks\nin this lab.
100
00:11:33,990 --> 00:11:36,830
Task 1, verify basic connectivity.
101
00:11:39,559 --> 00:11:43,049
Task 3, verify HSRP configuration.
102
00:11:43,049 --> 00:11:46,740
And task 4, assign HSRP priorities and preempt.
103
00:11:46,740 --> 00:11:52,039
So, for this lab preview let's just do task\n1 and task 2.
104
00:11:53,590 --> 00:11:58,180
It says this task involves verifying the connectivity\n
105
00:12:01,379 --> 00:12:07,320
Verify all non-HSRP IP addresses on each device\n
106
00:12:11,029 --> 00:12:15,389
So, the CLI of Router1 is already open.
107
00:12:34,590 --> 00:12:41,720
FastEthernet0/0 is correct, and FastEthernet0/1\n
108
00:12:41,720 --> 00:12:43,440
Now let's check out the switches.
109
00:12:43,440 --> 00:12:48,190
Oh, I'm getting an update for NetSim, I will\n
110
00:12:48,190 --> 00:12:53,720
Okay, ASW1, it has an IP address in VLAN1.
111
00:13:07,779 --> 00:13:11,600
Okay, next the distribution switches.
112
00:13:24,850 --> 00:13:28,730
And HSRP, I guess we will configure later.
113
00:13:38,240 --> 00:13:42,980
And FastEthernet3,4 and 5 are correct also.
114
00:13:42,980 --> 00:13:46,920
Okay, last up, the two clients, the two PCs.
115
00:13:46,919 --> 00:13:51,610
So, to check the IP address here let's use\nIPCONFIG.
116
00:13:56,620 --> 00:14:01,080
The default gateway is 3.3, which is correct.
117
00:14:01,080 --> 00:14:06,800
And I guess later we will change this to use\n
118
00:14:06,799 --> 00:14:09,959
Okay, finally I'll check on Client2.
119
00:14:12,940 --> 00:14:16,350
IP address 3.30, or sorry, 3.40.
120
00:14:22,080 --> 00:14:27,480
Okay, so step 2, verify that Client1 can ping\n
121
00:14:33,700 --> 00:14:39,230
Alright, we're getting a reply so no problems\nthere.
122
00:14:39,230 --> 00:14:43,909
And how about Client2, can it ping DSW2's\nVLAN1 interface?
123
00:14:51,840 --> 00:14:56,950
And then verify that Client1 and Client2 can\n
124
00:15:07,200 --> 00:15:15,940
I'll do the same back on Client1.
125
00:15:17,139 --> 00:15:23,399
Router1's FastEthernet0/0 interface, oh it's\nnot labelled here.
126
00:15:23,399 --> 00:15:27,199
Okay, well we can ping it so, it's not a problem.
127
00:15:27,200 --> 00:15:31,259
Actually let me use CDP to see what's connected\nhere.
128
00:15:31,259 --> 00:15:33,279
This is a command we'll cover later in the\ncourse.
129
00:15:35,230 --> 00:15:41,750
Okay, so FastEthernet0/0 is the one connected\nto DSW1, here.
130
00:15:41,750 --> 00:15:47,460
And FastEthernet0/1 is the one connected to\nDSW2, got it.
131
00:15:55,190 --> 00:16:00,800
So on DSW1 and DSW2, create an HSRP group\n
132
00:16:02,750 --> 00:16:07,809
Okay, so this is something a little different.
133
00:16:07,809 --> 00:16:13,059
The distribution switches are going to be\n
134
00:16:14,620 --> 00:16:18,610
So instead of configuring HSRP on the routers,\n
135
00:16:18,610 --> 00:16:24,860
to configure it the distribution switches,\n
136
00:16:24,860 --> 00:16:27,529
Okay good, so this will be something a little\ndifferent.
137
00:16:31,039 --> 00:16:35,649
CONF T. And what is the interface?
138
00:16:43,190 --> 00:16:46,920
Or, DO SHOW IP INTERFACE BRIEF.
139
00:16:54,769 --> 00:16:57,279
STANDBY, and we're using group number 3.
140
00:17:21,599 --> 00:17:27,079
Okay, next workstations and access layer switches\n
141
00:17:29,279 --> 00:17:34,240
On Client1 and Client2, configure the default\n
142
00:17:34,240 --> 00:17:41,000
Okay, so to do this we have to use a special\ncommand for NetSim.
143
00:17:44,390 --> 00:17:49,120
That is not a Cisco command, that is a command\n
144
00:18:02,680 --> 00:18:06,180
And let me just check with IPCONFIG.
145
00:18:12,859 --> 00:18:19,959
Okay next, on ASW1 and ASW2, configure the\n
146
00:18:19,960 --> 00:18:23,240
Okay, so this is again something I haven't\n
147
00:18:23,240 --> 00:18:28,240
So, ASW1 and ASW2 are Layer 2 switches.
148
00:18:28,240 --> 00:18:32,440
However, even on Layer 2 switches they are\n
149
00:18:32,440 --> 00:18:38,480
Sorry about that, one IP address for management,\n
150
00:18:40,900 --> 00:18:45,300
I will explain this later in the course.
151
00:18:45,299 --> 00:18:46,869
But they don't have a routing table.
152
00:18:46,869 --> 00:18:52,779
So, to specify the default gateway you can't\n
153
00:18:55,460 --> 00:19:02,480
IP DEFAULT-GATEWAY, and then put in the IP\naddress, 172.16.3.1.
154
00:19:02,480 --> 00:19:07,490
Okay, and I will do the same on ASW2.
155
00:19:07,490 --> 00:19:14,480
CONF T...oops, CONF T. IPCONFIG, nope, that\nis the PCs.
156
00:19:14,480 --> 00:19:19,099
IP DEFAULT-GATEWAY 172.16.3.1.
157
00:19:20,599 --> 00:19:27,230
Okay, so next we would go on to verify our HSRP\n
158
00:19:27,230 --> 00:19:29,650
like priorities and preemption.
159
00:19:30,759 --> 00:19:36,410
Now, just out of curiosity I want to grade\n
160
00:19:37,410 --> 00:19:41,060
It won't say that we completed the entire\n
161
00:19:41,059 --> 00:19:43,089
yet, but let's see how we did.
162
00:19:45,170 --> 00:19:47,420
And as expected, 'you missed one or more commands\nin the lab'.
163
00:19:47,420 --> 00:19:50,720
That's okay, we didn't finish it yet.
164
00:19:50,720 --> 00:19:53,250

165
00:19:53,250 --> 00:19:57,519

166
00:20:00,349 --> 00:20:02,230
The configurations are correct.
167
00:20:02,230 --> 00:20:07,190
So that means our...here, IP DEFAULT-GATEWAY\n
168
00:20:07,190 --> 00:20:12,330
DSW1 and DSW2, we are missing commands.
169
00:20:12,329 --> 00:20:15,189
Yeah, priority and preemption.
170
00:20:15,190 --> 00:20:22,019
However, the STANDBY 3 IP command is correct,\n
171
00:20:22,019 --> 00:20:25,859
