1
00:00:00,600 --> 00:00:01,500
Hello everybody.
2
00:00:01,500 --> 00:00:06,950
Welcome to our single area or SPF configuration.
3
00:00:06,950 --> 00:00:12,480
Lap This is gonna be a real fantastic session.
4
00:00:12,480 --> 00:00:13,590
We are gonna live.
5
00:00:13,710 --> 00:00:16,490
We are gonna learn lots of new things.
6
00:00:16,560 --> 00:00:24,990
We are going to learn how to configure or SPF and we are going to provide dynamic routing communication
7
00:00:25,350 --> 00:00:27,930
between the end devices too.
8
00:00:28,710 --> 00:00:29,970
So let's go.
9
00:00:29,970 --> 00:00:34,500
We have three steps that we should do.
10
00:00:34,500 --> 00:00:46,780
The first step is all interface conflicts are made before coming for your single area or SPF area zero
11
00:00:47,350 --> 00:00:57,100
between all rounders to provide food connectivity between all pieces in network.
12
00:00:57,480 --> 00:01:06,680
Pretty cool as you can see that in the figure we have four others connected to each other.
13
00:01:06,780 --> 00:01:13,380
But the question is saying that all interface conflicts are made before.
14
00:01:13,470 --> 00:01:14,970
That's a good news guys.
15
00:01:14,970 --> 00:01:19,440
That means Hey dude you're a professional anymore.
16
00:01:19,440 --> 00:01:25,720
You don't need to configure an interface you know it's already OK.
17
00:01:25,830 --> 00:01:28,310
I know that you can do it anymore.
18
00:01:28,350 --> 00:01:31,210
That's pretty simple for you guys.
19
00:01:31,320 --> 00:01:45,100
All right this second one show IP protocols and show ip route commands and check the output good and
20
00:01:45,220 --> 00:01:52,990
three room show IP SPF and show IP or SPF neighbors commands.
21
00:01:52,990 --> 00:01:57,470
And check the out of Troy IP SPF database.
22
00:01:58,150 --> 00:02:02,110
Okay let's go as you can see it.
23
00:02:02,200 --> 00:02:12,910
Let's talk about the topology some first rather one is connected to two and three and to the left of
24
00:02:13,840 --> 00:02:26,390
them for a one allow 1 0 segment what I'm going to do is I'm going to configure Rather's four or SPF
25
00:02:26,440 --> 00:02:28,860
routing to do it.
26
00:02:28,880 --> 00:02:38,500
I'm gonna check the interfaces network ideas that rudders are connected to.
27
00:02:38,500 --> 00:02:46,180
Then I'm going to advertise that network to my neighbors and I'm going to provide full connectivity
28
00:02:46,210 --> 00:02:56,060
between four Rather's and then four pieces also there's gonna be a really really cool session.
29
00:02:56,360 --> 00:03:00,770
And let's start with the first step.
30
00:03:02,590 --> 00:03:03,100
Okay.
31
00:03:03,110 --> 00:03:08,010
All interface conflicts are made before calling for your single or else.
32
00:03:08,030 --> 00:03:16,350
Between all Rather's to provide full connectivity I'm starting with rather why here is my pay cut.
33
00:03:16,360 --> 00:03:21,430
Trace sir let's go with their rather warm first
34
00:03:24,300 --> 00:03:31,820
enable but I'm going to show you that we're rather one is connected first.
35
00:03:32,170 --> 00:03:38,020
Rather one is connected to three different networks.
36
00:03:38,140 --> 00:03:40,360
As you can see that it's
37
00:03:45,040 --> 00:03:55,700
yellow and that zero network it's the wealth that zero network and it's third in that zero network.
38
00:03:56,450 --> 00:04:05,130
But while making my SPF configuration you don't really memorize you don't really need to memorize this.
39
00:04:05,250 --> 00:04:11,830
We have a command which is showing us which interfaces are related to which networks and we are going
40
00:04:11,830 --> 00:04:14,010
to advertise that networks.
41
00:04:14,130 --> 00:04:20,250
OK watch me first.
42
00:04:20,310 --> 00:04:26,960
I'm in the CLIA and I'm running show IP in their phase.
43
00:04:27,080 --> 00:04:41,510
Brief comment as you can see that our Jaeger 0 0 interface has an IP address of eleven that one and
44
00:04:41,510 --> 00:04:50,770
the others are 211 13 that one because of I'm using a sledge to any force having them mask with this
45
00:04:51,760 --> 00:05:03,440
my network I.D. are Teyla eleven that zero twelve that zero and in the Zero all right let's go county
46
00:05:04,700 --> 00:05:19,300
and rather or SPF I need to define a process I first this process I.D. must match on for Rather's two
47
00:05:20,600 --> 00:05:29,540
for exchanging or SPF roots rather as before I can change an arbitrary thing I'm going to use one rather
48
00:05:29,540 --> 00:05:45,630
was being far the first thing I should do when configuring or SPF is defining the rather IP OK rather
49
00:05:45,650 --> 00:05:49,610
i.e. it's not an IP address.
50
00:05:49,650 --> 00:05:58,990
As I told you before but I'm going to define a unique rather idea for each my brothers.
51
00:05:59,310 --> 00:06:06,640
And this gonna be one one one one for my rather one or other.
52
00:06:06,660 --> 00:06:17,250
I define the rods variety to the second step is advertising the networks that we are directly connected
53
00:06:17,370 --> 00:06:28,860
to to be our brothers and doing it using network command the first network and directly connected is
54
00:06:29,580 --> 00:06:34,450
delay 1.0.
55
00:06:34,600 --> 00:06:51,180
Wild Card is 0 0 0 255 because this network contains the IP addresses beginning from 11 that 1 to 2
56
00:06:51,200 --> 00:07:04,350
in the two hundred and fifty four so that means that the first three bits are constant my ip addresses
57
00:07:04,350 --> 00:07:07,740
will stuck with this and the last bit is arbitrary
58
00:07:11,050 --> 00:07:19,670
and I'm going to define the area it says use area zero in the question and I'm using eraser.
59
00:07:19,790 --> 00:07:20,450
All right.
60
00:07:20,450 --> 00:07:21,710
Pretty cool.
61
00:07:21,710 --> 00:07:28,770
I'm gonna use the same thing for 12 and 13.
62
00:07:30,540 --> 00:07:33,710
Practical let's go to the rather two
63
00:07:37,050 --> 00:07:38,390
I'm in a rather two
64
00:07:43,210 --> 00:07:44,700
show IP in the race.
65
00:07:44,730 --> 00:07:53,590
Brave rather too is directly connect to the twelve twenty two and twenty four networks as you can see
66
00:07:57,060 --> 00:08:08,480
rather as Pier 1 again please keep in mind that process I.D. must match on for Rather's I'm going to
67
00:08:08,480 --> 00:08:13,520
give the rather I'd you first and that should be this one.
68
00:08:14,650 --> 00:08:25,910
No rather idea should be unique for each rather that is the idea so I'm using 2 2 2 2 for the other
69
00:08:25,950 --> 00:08:35,300
2 and the last thing I need to configure is my network statements not work
70
00:08:37,770 --> 00:08:38,520
zero
71
00:08:41,700 --> 00:08:54,120
and are a zero OK because I'm using a sledge 2 for my network idea is twenty two that zero and because
72
00:08:54,120 --> 00:09:06,640
I'm using a slash 2 and 4 again my wildcard is the 0 0 0 and 255 please keep in mind that if you're
73
00:09:06,670 --> 00:09:16,650
confusing Oh my God which work her mask I need to use you can reword this too you can read rework your
74
00:09:16,650 --> 00:09:30,210
subnet mask you should use 0 instead of 255 then you should use 255 instead of 0 because of on the subnet
75
00:09:30,240 --> 00:09:42,300
mask is 255 255 255 0 I'm using 0 0 0 255 for my wildcard mask.
76
00:09:43,030 --> 00:09:44,400
Ok I'm gonna also
77
00:09:47,670 --> 00:09:50,890
advertise these networks too.
78
00:09:51,480 --> 00:10:00,730
All right pretty cool but I'm expecting something to see but I couldn't I couldn't see it here.
79
00:10:00,860 --> 00:10:01,840
That's what I knew.
80
00:10:01,850 --> 00:10:15,840
Really need to see as you can see that as soon as I type my network statements rather to rather to has
81
00:10:15,850 --> 00:10:20,210
a ways P.F. neighbor right now.
82
00:10:20,410 --> 00:10:24,890
And it's rather one.
83
00:10:24,930 --> 00:10:25,900
Let's see what happened.
84
00:10:25,900 --> 00:10:31,540
Now I configured the SPF for this guy.
85
00:10:32,870 --> 00:10:45,560
And for this guy I didn't configure SPF yet 4 rather 3 and 4 but as soon as I configure the network
86
00:10:45,560 --> 00:10:53,140
statement for the link between rather one or rather two they became and was.
87
00:10:53,270 --> 00:10:58,070
Ed you sent NMR all right.
88
00:10:58,280 --> 00:11:11,350
Now let's take a look to the third brother enable county Varadero SPF 1 rather eighty three territory
89
00:11:11,380 --> 00:11:14,260
three and I need to take a look today.
90
00:11:14,590 --> 00:11:16,280
Show IP interface please.
91
00:11:16,950 --> 00:11:25,300
Please keep in mind that you can use show commands even if in you are in conflict grab the remote or
92
00:11:25,300 --> 00:11:36,120
config mode or config if not by using the to comment at the beginning to show IP interface brave I can
93
00:11:36,120 --> 00:11:45,930
say this or I can go to the privileged exec mode and I can use the show IP interface brief and the end
94
00:11:45,930 --> 00:11:50,170
result always will be the same.
95
00:11:50,390 --> 00:11:50,680
Okay.
96
00:11:50,690 --> 00:11:57,140
This rather has this networks and I'm going to configure them with network.
97
00:11:57,140 --> 00:11:59,150
Oh well I mean network
98
00:12:01,780 --> 00:12:05,800
0 0 0 255 and is 0
99
00:12:12,500 --> 00:12:14,180
13 and
100
00:12:17,070 --> 00:12:17,670
34.
101
00:12:20,780 --> 00:12:25,700
I'm expecting to see another membership between rather one and rather three right now.
102
00:12:25,700 --> 00:12:34,400
And yes as you can see that rather tree has a neighbor which is rather one and a more and now let's
103
00:12:34,400 --> 00:12:46,350
go to the rather for I am rather for how enable and come to rather overspill from known network rather
104
00:12:46,350 --> 00:12:52,160
idea for 4 4 4 and network statements
105
00:12:54,860 --> 00:12:58,430
networks will be 44
106
00:13:04,350 --> 00:13:08,720
quarter for 24 and
107
00:13:11,350 --> 00:13:23,660
34 I'm expecting to neighbor ship right now for is adjacent with 2 and by 8 it was already adjacent
108
00:13:23,660 --> 00:13:27,400
with the 3 or yes.
109
00:13:27,560 --> 00:13:45,120
Okay 4 is adjacent with 2 and 3 right now so that and I think that we accomplished the first step step
110
00:13:45,120 --> 00:13:48,850
Von okay man.
111
00:13:48,940 --> 00:13:50,760
I completed you
112
00:13:53,610 --> 00:14:04,400
but to where fire configuration we need to use ping from P.S. 1 2.
113
00:14:04,400 --> 00:14:07,240
P.S. 4.
114
00:14:07,310 --> 00:14:07,930
Let's do it
115
00:14:13,090 --> 00:14:17,810
I'm in P.S. 1.
116
00:14:17,940 --> 00:14:20,160
I'm going to comment prompt and typing.
117
00:14:20,170 --> 00:14:20,860
Ping
118
00:14:23,570 --> 00:14:34,090
four 5 which is the IP address of PCI for let's see that was going on all right I got the reply.
119
00:14:34,140 --> 00:14:43,260
And that means my ISP configuration is working properly right now and I can go to the second step in
120
00:14:43,260 --> 00:14:44,420
the second step.
121
00:14:44,460 --> 00:14:56,580
We need to run Choi IP protocols and show ip route commands let's go to the rather one and run
122
00:15:01,350 --> 00:15:06,720
show IP protocols command.
123
00:15:06,820 --> 00:15:07,380
All right.
124
00:15:07,390 --> 00:15:16,740
That's what I expect to see I'm running or spear with a process idea of one.
125
00:15:17,260 --> 00:15:34,920
I'm just using one area I'm running for networks these guys and I have these guys in my network that's
126
00:15:34,920 --> 00:15:35,640
pretty cool.
127
00:15:35,670 --> 00:15:46,610
That's why show IP protocols say to us and let's take a link to the show IP Rudd command through IP
128
00:15:46,770 --> 00:15:49,830
Raul All right.
129
00:15:49,910 --> 00:15:51,110
As you can see there.
130
00:15:51,350 --> 00:16:01,160
And as you can remember from our previous sessions connect them and local links are automatically appearing
131
00:16:01,160 --> 00:16:11,180
already in my show IP right outputs but what I need to see in here also I'm learning
132
00:16:13,780 --> 00:16:18,040
five different networks using the O.
133
00:16:18,430 --> 00:16:21,200
Which means or its path.
134
00:16:21,490 --> 00:16:26,090
I dunno this one first where it is.
135
00:16:26,200 --> 00:16:27,930
I dunno this one.
136
00:16:28,120 --> 00:16:45,120
I dunno this one but I learn them via the other fathers that they're using all SPF protocol to all right.
137
00:16:48,320 --> 00:17:00,690
Hey man my second step is also with my accomplished okay.
138
00:17:00,730 --> 00:17:07,570
Let's take a look to the last step the last step of saying as to run short PSP speed database and show
139
00:17:07,570 --> 00:17:11,650
I put Dave neighbour's comments.
140
00:17:11,800 --> 00:17:18,360
I'm a rather one and less strong show IP always peer database comment
141
00:17:21,010 --> 00:17:32,320
show at SPF database command is showing us the topology table and we bring us the general map of our
142
00:17:32,980 --> 00:17:35,690
network.
143
00:17:35,880 --> 00:17:41,970
I know how to go to the destinations y edited database but the best parts are being installed to the
144
00:17:42,660 --> 00:17:47,820
IP routing packed IP routing table.
145
00:17:47,880 --> 00:17:48,370
Okay.
146
00:17:48,390 --> 00:17:53,330
Let's take a look to the show IP or SPF neighbor zone rather run.
147
00:17:53,610 --> 00:18:01,440
Well they expect to see is rather 2 and 3 which are directly connected to the rather one and the s.
148
00:18:02,630 --> 00:18:11,900
As you can see that and see the seeing the rather ideas that I configured for Rather to enter a and
149
00:18:11,960 --> 00:18:18,750
I'm seeing the interface and IP address information as well.
150
00:18:18,770 --> 00:18:23,260
All right guys that was a really cool session and we finished it.
151
00:18:23,270 --> 00:18:25,680
Thanks for viewing.
152
00:18:25,690 --> 00:18:27,520
Ah or a spare lap.
