1
00:00:00,420 --> 00:00:07,520
In the section we're going to talk about DHC poor recall and let's go ahead with the DNC diversion for
2
00:00:07,520 --> 00:00:17,440
first DGP is a client server protocol that automatically provides IP host with its IP address and other
3
00:00:17,440 --> 00:00:24,400
related configuration information such as some mask and the default gateway or the D.A. or something
4
00:00:24,400 --> 00:00:25,540
like that.
5
00:00:25,630 --> 00:00:34,450
DHP uses port numbers 6:54 And for example if you are managing a network when work with 1000 clients
6
00:00:34,720 --> 00:00:42,970
it is almost impossible to assign IP address configuration manually for each client so the ATP is almost
7
00:00:42,970 --> 00:00:47,640
mandatory for big corporate networks.
8
00:00:47,680 --> 00:00:55,160
The chip process goes through four states while assigning an IP address to the client.
9
00:00:55,180 --> 00:01:10,080
These days are often every day related as Dora discover offer request and acknowledgment in the discovery
10
00:01:10,080 --> 00:01:15,690
stage declines sends a broadcast message on the network.
11
00:01:15,690 --> 00:01:25,510
As you can see here and search for an active JTP server when a DC peso receives the DHC we discover
12
00:01:25,530 --> 00:01:29,360
message for my client which is an IP address.
13
00:01:29,490 --> 00:01:30,730
Request.
14
00:01:30,760 --> 00:01:40,050
This so preserves an IP address for the client and makes the leaves over by sending DCP off a message
15
00:01:40,050 --> 00:01:51,130
to clients in response to the DCP over the client replies with a DCP request broadcast to the server
16
00:01:51,130 --> 00:01:54,790
requesting the Orford IP address.
17
00:01:54,790 --> 00:02:02,520
When the DNC Bistro receives the DCP request message from the client the configuration process anthers
18
00:02:02,530 --> 00:02:12,310
the final stage the acknowledgements page in sending a DCP ack packet to the client and this packet
19
00:02:12,370 --> 00:02:20,290
includes the lease duration and any other configuration information that the client might have requested.
20
00:02:23,520 --> 00:02:32,940
Dynamic Host Configuration DHC portico is a server protocol assigning dynamic IP address to the computer
21
00:02:33,280 --> 00:02:42,960
LDH DHC server enables computers to request the IP addresses and networking per Matres automatically
22
00:02:43,230 --> 00:02:50,180
reducing the need for a network administrator or a user configured these things Menil.
23
00:02:50,580 --> 00:02:54,900
We can also use our brothers as DCP servers.
24
00:02:54,900 --> 00:03:02,310
And here is the configuration to go for your brother as a DCP server.
25
00:03:02,310 --> 00:03:08,020
First we need to define an IP pool by typing.
26
00:03:08,040 --> 00:03:14,750
I PDC pay pool and the name of pool which is my pool for this example.
27
00:03:15,120 --> 00:03:23,960
Ok then we are getting into DCP config more as you can see and we're typing the address range for us.
28
00:03:23,960 --> 00:03:33,330
The the thing we are going to define for this address range we need to type network command and we need
29
00:03:33,330 --> 00:03:37,390
to type the network ID with a subnet mask.
30
00:03:37,660 --> 00:03:55,110
OK which means our range will be between cell 41 was 0 2 24 Okay I'm going to start from 1 1 2 until
31
00:03:56,250 --> 00:03:58,280
250 to 200 and for.
32
00:03:58,290 --> 00:03:59,450
OK.
33
00:03:59,490 --> 00:04:07,950
And then we're defining a default route which is the default gateway and default gateway of this network
34
00:04:07,990 --> 00:04:13,960
will be this interface of this rather which is 10:41 one.
35
00:04:14,220 --> 00:04:22,360
OK then we are defining a DNS server and our DNS server will be this.
36
00:04:22,500 --> 00:04:28,120
Then we're also defining a domain name which isn't there or killed that come.
37
00:04:28,520 --> 00:04:29,430
OK.
38
00:04:29,730 --> 00:04:39,500
But then the thing here also is as you can see in the last command and defining something more I think
39
00:04:39,500 --> 00:04:52,010
DCP excluded address and won't want to five which means I'm escalating this range.
40
00:04:52,130 --> 00:04:55,310
OK I want to use this range.
41
00:04:55,330 --> 00:05:08,450
That means some clear address range for PC one will be starting from 1 to 6 because one one is our default
42
00:05:08,450 --> 00:05:10,970
gateway and won't be used.
43
00:05:11,270 --> 00:05:13,860
And I'm also excluded.
44
00:05:13,910 --> 00:05:24,060
This range which includes my default gateway to because of this the address range that PC one can use
45
00:05:24,180 --> 00:05:26,160
will be this range
46
00:05:29,390 --> 00:05:40,420
to fight the DCP server options or for other weekend use show run section DHC P shoy P DHC P binding
47
00:05:40,460 --> 00:05:51,130
and so with the takes commands if you want to essay a dynamic IP address to others the interface you
48
00:05:51,130 --> 00:05:58,850
can use IP address and date City command under the related interface mode.
49
00:05:59,110 --> 00:06:06,580
This is not something that we're usually using but you may be faced with these questions in your eggs.
50
00:06:06,910 --> 00:06:17,740
So here we are getting into the interface more by typing interface 00 which is here and by typing I
51
00:06:17,740 --> 00:06:28,470
purchased the c p command rather is Greig's zero zero interface Gethers an IP address from the DTP server
52
00:06:28,600 --> 00:06:31,930
dynamically.
53
00:06:32,100 --> 00:06:42,720
The most common use of rather for DTP services is the DHC peer relay DTP really is the rudder forwards.
54
00:06:42,750 --> 00:06:50,220
They simply broadcast packets through the ATP server which is also known as the helper.
55
00:06:50,430 --> 00:07:01,460
For example if PC Wan makes the FDCPA request rather one will forward this packet to the well it DTP
56
00:07:01,610 --> 00:07:06,690
software which is 10:41 to five four days example.
57
00:07:08,360 --> 00:07:18,890
Let's go ahead DCP version 6 IP version 6 prides itself as a portal code that supports many dynamic
58
00:07:18,890 --> 00:07:22,950
plug and play functionalities as a result.
59
00:07:22,970 --> 00:07:32,240
There are multiple ways to assign IP addresses in IP version 6 to configure IP version 6 has global
60
00:07:32,260 --> 00:07:45,100
unicast globally we have two options and they are slack and the version 6 in slacke option rather can
61
00:07:45,100 --> 00:07:54,080
send IP address graphics length and the default gateway information to the clients in DHP version 6
62
00:07:54,080 --> 00:08:03,830
option DHC server sans IP address Perfect's length default gateway DNS server and domain name information
63
00:08:03,860 --> 00:08:04,740
to clients.
64
00:08:04,820 --> 00:08:06,890
Similar type before.
65
00:08:08,500 --> 00:08:10,830
Let's go ahead with the slack.
66
00:08:11,120 --> 00:08:20,590
Flag option rather can offer three types of information to Ehsaan Dynamic IP Address conflagration.
67
00:08:20,590 --> 00:08:30,970
The first is slacke only in this option rather offers to use the information that rather sand's on lay
68
00:08:31,740 --> 00:08:32,190
in.
69
00:08:32,200 --> 00:08:41,590
The second option which is slack and Betsi perversions 6 in this option rather offer is to use the information
70
00:08:41,590 --> 00:08:49,470
that rather Sants and offers through the rest of the options from the DCP version 6.
71
00:08:49,460 --> 00:08:59,920
So for example DNS or something like that in that third option rather of first to use just the ECP version
72
00:08:59,920 --> 00:09:02,950
6 server OK.
73
00:09:02,950 --> 00:09:11,810
This is how select works actually the host makes the request first which is there other songs they should
74
00:09:11,820 --> 00:09:20,650
message and saying that hey rather I need are two words and six options OK or I prefer to use six rather
75
00:09:21,390 --> 00:09:27,490
gets this request and can reply in three ways.
76
00:09:27,700 --> 00:09:31,660
The force of a reply is select only which includes.
77
00:09:31,660 --> 00:09:35,860
Here is your IP prefix length and the gateway.
78
00:09:36,040 --> 00:09:38,290
Replying to the host.
79
00:09:38,380 --> 00:09:43,500
The second option is to select and VCP version 6 which includes.
80
00:09:43,500 --> 00:09:53,320
Here is your IP Perfect's length but as the DCP version 6 server for DNS and the domain name in here
81
00:09:53,320 --> 00:10:00,520
we are defining something we are providing some of the information from router and we are defining some
82
00:10:00,520 --> 00:10:09,880
of the other informations from the DCP version 6 and the last message can be the simple version 6 which
83
00:10:09,880 --> 00:10:12,390
means I'm sorry my friend.
84
00:10:12,520 --> 00:10:18,600
I ask the ATP version 6 we can use our rather as a DCP So we're in.
85
00:10:18,610 --> 00:10:24,670
I Pugin 6 networks too similar to IPV for in this configuration.
86
00:10:24,670 --> 00:10:34,000
Rather one offers DNS so any domain name as you can see the first we're defining a pool again by typing
87
00:10:34,060 --> 00:10:42,990
IP version 6 DTP pool and the name of the pool and we are defining the DNS server and the domain name.
88
00:10:43,370 --> 00:10:56,680
OK and in here we are also another configuration IP version 6 and the other config file.
89
00:10:57,310 --> 00:11:06,400
This flag is required as it will inform glanced through rather advertisement message that they have
90
00:11:06,400 --> 00:11:12,430
to use DTP version 6 to receive extra information works.
91
00:11:12,760 --> 00:11:23,320
We can also use our rather as a DCP version 6 relate to and this rather in here for the server brought.
92
00:11:23,360 --> 00:11:26,830
Kept work Spackles to the DCP server.
93
00:11:27,010 --> 00:11:34,810
And here is the configuration of the DCP relay in IPV 6 networks we are getting into the interface mode
94
00:11:34,810 --> 00:11:47,230
again and the command is this time IP version 6 DGP relay destination and the IP address of the removed.
95
00:11:47,470 --> 00:11:49,240
Did pay for.
