1
00:00:15,840 --> 00:00:23,900
This is a packet tracer campus network topology that we're going to use in multiple videos in this course.
2
00:00:23,970 --> 00:00:32,770
This topology gives us a nice basis to learn many of the technologies found in the CCMA exam.
3
00:00:32,790 --> 00:00:39,610
This is a campus network consisting of two core switches and three access switches.
4
00:00:39,870 --> 00:00:42,820
Even though this topology is quite small.
5
00:00:42,870 --> 00:00:50,160
Imagine that you have many access switches in this topology configuring more than three axis switches
6
00:00:50,160 --> 00:00:57,960
is redundant and will simply take up time rather than you learning new things so I've limited the topology
7
00:00:57,960 --> 00:01:00,570
to three access switches.
8
00:01:00,690 --> 00:01:09,330
We've also got three pieces in the topology one connected to each axis switch as well as a server connected
9
00:01:09,390 --> 00:01:11,550
to one of the core switches.
10
00:01:11,820 --> 00:01:19,830
We have an Internet router that will configure to connect the campus network to the Internet on the
11
00:01:19,830 --> 00:01:20,310
Internet.
12
00:01:20,310 --> 00:01:23,870
We have a Google DNS server.
13
00:01:24,230 --> 00:01:30,880
8 8 8 8 8 8 and a Cisco dot com server in the real world.
14
00:01:30,900 --> 00:01:40,230
If I'm paying Google dot com that DNS name needs to be resolved by a DNS server.
15
00:01:40,230 --> 00:01:46,010
In my example I'm using 8 2 2 8 8 8 8 8 8 8 as my DNS server.
16
00:01:46,440 --> 00:01:54,610
So that is a Google DNS server and we'll replicate that in our packet tracer network.
17
00:01:54,630 --> 00:02:01,890
Now there's a lot to do and hence we going to split up the configuration of this topology into multiple
18
00:02:01,890 --> 00:02:03,070
videos.
19
00:02:03,180 --> 00:02:05,960
You'll firstly need to power up the switches.
20
00:02:06,150 --> 00:02:13,710
You'll have to configure basics such as host names IP addresses usernames and passwords and into VLAN
21
00:02:13,710 --> 00:02:16,920
routing on the call switches.
22
00:02:16,920 --> 00:02:22,980
As this is a layer to topology you're going to need to configure the links between the switches as trunk
23
00:02:22,980 --> 00:02:28,090
ports and the ports to the pieces as access ports.
24
00:02:28,200 --> 00:02:32,330
The pieces in this network are in different villains.
25
00:02:32,340 --> 00:02:33,860
P.S. One is in VLAN 10.
26
00:02:33,870 --> 00:02:36,000
P.S. 2 is in VLAN 20.
27
00:02:36,000 --> 00:02:44,010
And P.S. 3 is in VLAN 40 so you'll need to configure these ports on the access switches with the relevant
28
00:02:44,010 --> 00:02:45,330
v glands.
29
00:02:45,420 --> 00:02:52,150
You'll also need to configure the server in vlan 100 on this course switch.
30
00:02:52,260 --> 00:02:58,410
In addition because this is a layer to topology spanning tree is going to be used spanning tree runs
31
00:02:58,410 --> 00:03:02,360
by default on Cisco switches but it's not optimized.
32
00:03:02,490 --> 00:03:07,600
You will need to optimize the spanning tree in this network.
33
00:03:07,680 --> 00:03:13,440
You going to configure the switch on the left as the route switch for some villains and the switch on
34
00:03:13,440 --> 00:03:19,950
the right as the route switch for other villains in the real world on your access switches as you may
35
00:03:19,950 --> 00:03:27,510
have devices in multiple villains so as an example you may have IP phones as well as pieces in your
36
00:03:27,510 --> 00:03:34,320
topology and you're going to want to send some traffic to the call using this uplink and other traffic
37
00:03:34,320 --> 00:03:37,050
to the core using this uplink.
38
00:03:37,140 --> 00:03:44,670
So we're going to want to optimize spanning tree for load sharing but also to ensure that we are not
39
00:03:44,670 --> 00:03:50,640
blocking links that can negatively affect the throughput through our network.
40
00:03:50,760 --> 00:03:57,960
As an example if access switch too became the route it would mess up the forwarding of traffic through
41
00:03:57,960 --> 00:03:59,250
the network.
42
00:03:59,310 --> 00:04:05,040
So we need to optimize our spending tree to make sure that the course switches all the route switches
43
00:04:05,460 --> 00:04:08,760
and that we load share traffic across them.
44
00:04:08,760 --> 00:04:14,700
We also are going to want to make sure that these two links in the core are configured to use ether
45
00:04:14,700 --> 00:04:20,700
channel so that both are forwarding rather than having one of the ports blocking.
46
00:04:20,700 --> 00:04:27,510
We need to configure the call switches for interview land routing so they're going to need multiple
47
00:04:27,510 --> 00:04:30,100
switched virtual interfaces configured.
48
00:04:30,480 --> 00:04:36,000
They're going to have to be configured with writing protocols such as EAI GOP so that they can exchange
49
00:04:36,000 --> 00:04:39,020
routes with the ISIL router.
50
00:04:39,150 --> 00:04:46,230
The ISIL rider needs to be configured with basic configurations but it also needs to be configured with
51
00:04:46,230 --> 00:04:55,950
EAI GOP and net or network address translation to ensure that these devices in our network can get to
52
00:04:55,950 --> 00:05:03,660
the Internet now one of the things to think about when you have multiple course switches is which switch
53
00:05:03,750 --> 00:05:09,700
becomes the default gateway for your pieces after the access layer.
54
00:05:09,780 --> 00:05:17,580
We want multiple call switches for redundancy and full load sharing traffic across uplinks but which
55
00:05:17,670 --> 00:05:25,470
switch will be the default gateway for this P.C. if we configured the switch as the default gateway
56
00:05:25,890 --> 00:05:28,050
and that switch went down.
57
00:05:28,080 --> 00:05:32,750
P.S. One wouldn't be able to send traffic to other villains.
58
00:05:32,880 --> 00:05:40,710
So what we gonna want to do in the Corps is enable protocols such as H.S. IP or hot standby running
59
00:05:40,710 --> 00:05:41,910
protocol.
60
00:05:41,910 --> 00:05:46,380
So we need to configure H.S. or p on our core network.
61
00:05:46,440 --> 00:05:54,300
That means that rather than P.S. One P.S. two and P.S. three using one of the switches in the call as
62
00:05:54,300 --> 00:06:01,620
the default gateway they point to the virtual H.S. IP router if one of the course switches goes down.
63
00:06:01,620 --> 00:06:09,270
It's not a problem because traffic can be intervened and routed by the remaining core router however
64
00:06:09,360 --> 00:06:13,260
whenever you enable H.S. IP and you using it.
65
00:06:13,260 --> 00:06:19,360
In addition to spanning tree you're going to want to optimize the link between spanning tree and H.S.
66
00:06:19,370 --> 00:06:20,340
IP.
67
00:06:20,430 --> 00:06:29,720
In other words if so which one is the H.S. or P primary Rada or monster rider for VLAN 10 you're going
68
00:06:29,720 --> 00:06:34,480
to want it to be the spending tree root for VLAN 10.
69
00:06:34,500 --> 00:06:40,710
In other words you don't want a mismatch between your spending tree roots and your HS or P primary routers
70
00:06:41,460 --> 00:06:49,560
or active routers if he's the HS or P active Rata for VLAN 10 he needs to be the root for VLAN 10 if
71
00:06:49,560 --> 00:06:57,180
the switches the HSR P active router for VLAN 20 it needs to be the root for VLAN 20 so as you can see
72
00:06:57,180 --> 00:07:03,300
there's a lot to do we going to configure some of the basics initially and then as we continue we'll
73
00:07:03,300 --> 00:07:07,880
configure more and more to get this network fully working.
74
00:07:08,250 --> 00:07:16,950
I'm hoping that this gives you a practical real world example of how to configure networks but in addition
75
00:07:17,430 --> 00:07:25,470
I'm confident that It'll prepare you well for the CCMA exam so try and do the labs yourself.
76
00:07:25,470 --> 00:07:31,190
Download the packet tracer files and see if you can complete the list of tasks yourself.
77
00:07:31,320 --> 00:07:37,530
If you struggle or if you'd like to learn some additional tips and tricks watch my videos where I can
78
00:07:37,530 --> 00:07:38,700
figure the devices.
79
00:07:38,700 --> 00:07:52,050
Per the requirements given to us so let's get started configuring the campus network.
