Video Description

VLAN Trunking Protocol VLAN Trunking Protocol has nothing to do with bringing up a trunk. Instead we explain the process by which VLAN Trunking Protocol (VTP) carries VLAN information to all the switches in a VLAN Trunking Protocol domain. We'll provide some general description of how it works and then explain in more details the functions it performs. We'll introduce you to each of its three modes: Server Mode, Client Mode and Transparent Mode.

Video Transcription

00:04
the next topic of discussion is going to be villain trunk ing Protocol,
00:08
very unfortunately named because this protocol has nothing to do with bringing up trunks.
00:14
So
00:16
the two phone calls that we covered that have to do with trunk ing the trunk ing protocols are I sl interest, which Link and Toto too 20.1 cube
00:26
Really, and trucking protocol is dust named because it on Lee works over trunk links or it on Lee works over trunk ports.
00:35
Hence, it's called Dylan Trucking. Poor Call, but it has nothing to do with bringing up a truck.
00:41
Now, before I go into detail with V T. P.
00:45
Let's go over generally what it does.
00:48
Let's say at your work you have 56 switches and your boss tells you to go configure a villain 10 2030 40 and 50 on all 50 devices.
00:58
Well, before the advent of BTP,
01:00
you would have to manually log into each switch
01:03
and execute the command over and over again. Save the land. 10. Villain, 20 villain, 30 villain, 40 50 Then go to the next wish and do it all over again.
01:14
Beyond trucking protocol, actually, employees
01:18
a server client mechanism
01:21
where
01:22
if you make one switch BTP server, Orville and Trucking Protocol Server and the rest of your 49 switches as clients, if you create villain 10 2030 40 and 50 on the server, switch the clients, which will listen to what the server is doing, an automatically create villains 10 through 50 for you,
01:42
so really be operates in three modes.
01:46
The first mode is your BTP server mode.
01:49
Now going back just a bit. Remember that villains on your switch are stored in a file in Flash called Dylan dot dat.
01:59
Which Old Joe Villain database.
02:01
So the re T p server mode switch.
02:05
I can modify its villain dot that file. It is allowed to modify the villain dot dat file.
02:13
What does this modification constitute?
02:15
Well, adding a villain is a modification.
02:20
Deleting a villain is a modification.
02:23
Changing a villain's name or assigning it a name from null to something else. Like CCN A is a modification and changing a villain's maximum transmission unit, which by default is 1500 bytes to something else is a modification. So adding a villain, deleting a villain, naming a villain, changing of villains and to you.
02:44
So the VTB server mode switch
02:46
10 modifier to be land on that file
02:49
and these modifications are carried downstream from the server switch Envy TP advertisements.
02:57
The client switch. It's pretty easy to get
03:00
will listen to these modifications
03:04
sent out by the V t p server switch and do accordingly. So if the V t. P service, which adds Villain 10 through 50 the clients which is will also add villains 10 through 50
03:15
the VTB clients, which, however, is not allowed to modify its we land on that file. So if I'm on a client switch and I tried to
03:23
create a villain or change of plans, name or change of the lands, and to you or delete a villain, it will actually tell me that it's not allowed.
03:32
The last mode for BTP is your BTP transparent mode switch.
03:38
As the name suggests, the BTP transparent mood switch
03:44
will really be TV advertisements as in
03:49
in one port out the other.
03:51
But it will not apply the modifications carried in the BTP advertisements to itself so it will not comply with the switches the servers, which is demands
04:02
so if the servers which created the land. 10 2030. The transparent switch will not listen to the VP advertisements and create the land 10 2030.
04:12
However, the BTP transparent switch real forward BTP advertisements to downstream clients.
04:18
The VT be transparent, Moz, which is, however, allowed
04:23
to add and delete
04:25
its own villains, changed the villain into you, or change the villain name. So basically the transparent Moz, which can modify its be land on that file.
04:36
And for now, this concludes the V t p
04:40
nectar section and we'll start with the lab.
