1. Introduction: Hello everyone, Welcome to IPV6 addressing and
configuration lecture, which is the most
important and hot topic of networking industry. I'm going to explain
what is IPV6 address, how to implement IPV6 address, and how to implement
routing in IPV6 address. In detail, I will
explain you about how to design the network
for IPV6 address and Cisco Packet Tracer
simulator and how to create local and wide area network with the help of
IPV6 addressing, how to connect IPV6
devices with each other, and how to provide IPV6
addressing to end devices. And after that on router, I'm definitely share after
this IPV6 addressing, configuration and routing, there will be a
great exposure of IPV6 address and you can implement IPV6
addressing easily. So let's get started.
2. What is IPv6: Hello everyone, welcome to the very first lecture
of IPV6 addressing. In this class, I'm going to explain you about what is IPV6. But before I starting IPV6, we need to understand
the difference between IPV4 or IPV6. So let's get started
when IPV4 first. So as we know that IPV4
is an address of them for if we talk about the
size of my IPv4 address, it is 32-bit decimal address, and it is represented by a dot. The debates are divided
into four octet, eight dot, dot, dot it. In IPV4, we have classes, five classes of IP address. We have a, B, C, D, and E in which a, B, C classes are used
for networking, while D and E
classes are reserved for multicasting and scientific
research and recovery. To a wide range of IP address. We use the concept
of subnetting. Subnetting we use FLSA
them as well as VLS. Same concept if we talk about the complete IPV6
address detail than we have 4.29 billion addresses
are available in IPV4. Addresses are reserved
for default route, some are reserved for
loopback addresses, some are reserved for
another purposes. While now we have to
discuss about IPV6. Ipv6 is a huge address. Why it is the hot topic
of network industry, because it has a very, very large scales
of IPV6 addresses. Ipv6 address size is 128 bit and it is not represented by a
decimal because for example, if very present IPV6
in decimal concept, then we have to use
like here, up to 168. That's why they have changed
it into hexadecimal format. Now hexadecimal format is in this we can use numerical
value 0 to nine, as well as alphabets
from a to F. So 1011131415 are
respectively a to F values. So IPV6 address is
represented by a colon. So this is the sign of colon, and it is represented by hexa. So we have 16 columns,
16 columns, 16. So it is the representation
of 12345678. So in IPV6, we don't
have any classes. We can do subnetting, but here we don't
need it because we are going to use it
for private purpose. We can do subnetting
but we don't need it. And also I just want to
clear one thing in IPV4, we are using a subnet mask to divide network
ID and host ID, but an IPV6 address, you can directly use
a prefix length. Now, prefix length is
the same value as CIDR, an IPV4, we call it as CIDR, and in IPV6 we call
it as prefix lens. Now prefix length
is like slash 16, 30 to 486348096112 and last 128, if you remember IPV4 address, if you have seen our video
on Skillshare about IPV4, I have explained about 32 bits are divided into 81624328162432. Similarly, IPV6 addresses
are represented like this. And in this we don't
need any subnet mask. We can directly use this
prefix length value. Now we have to check how
IPV6 addresses are written. Let's move on to the next slide. Ipv6 is using hexa format. So zeros, zeros, zeros
0 to f, f, f, f.
3. IPv6 Addressing on end Devices: Hello everyone. Welcome again to the second class for
IPV6 implementation. This class, I'm going to explain how to assign IPV6
address two pieces. So we will create a lamb with the help of
switch and pieces. So let's get started. Here. I'm using Cisco Packet
Tracer simulator and I'm going to use 2960 switch. Here. I'm going to use
four pieces that will be connected to switch with
the help of straight cable, you can use automatic cable
also if you know the things. So I have connected for
devices with the switch, so it will create a land. Now. Now I want to use
IPV6 address here. So in my last video, I have implemented
that 20010 dB. It is reserved for examples
and documentations. But here we are going to use
private IP address space. So there is no need
to use 2001 actually. But if you want to use them, this is the best IP address, IPV6 address for example. So we have to click on PC, click on deck stop
and IP configuration. Now an IPV4, we use
this dialogue box, but then for IPV6 configuration,
we have to use this. We have three options for
giving the IPV6 address, DHCP, config and static. So I'm going to use here because
this is our first-class. So in IPV6 address, I'm going to use 2001 column. So I'm not going to
use 0 dB it here. Instead of that, I'm
going to use here 123. So you can check here, I'm going to use
zeros only for one. I have used two visits to
the 11123 and rest all are zeros because I want to explain you when i will of
the dialog box. After that, I will
open the dialog box. These are all zeros will
convert into double columns. So slash value here you have
to give the prefix length. For example, I'm
going to use 96 here. So this is the link
local address, same as the automatic
private IP address. We have worked in IPV4. And here you have to
use IPV6 gateway. So I'm going to use gateway
address here, 1123. So I'm here going to use a 100. So gateway is the address that the switch is going to
connect with that router. So I will connect
the router also, you can check that all the zeros are converted
into double column. So again, we have to
click on my second PC. Now this time I can use
directly double colon two. My syntax is 96, my prefix length 20011, brain D3, and double colon 100. You can directly use
double colon if you will use zeros and automatically
they will convert it. My third IPV6 addresses, 20011, Grundy three, double
colon three slash 96. Now I have copied this. You can check automatically, it is going to be converted. Last PC I have to
convert, configure. For 96. This is done. So my IPV6 addressing is
configured on my end device. Now the task is how to check that connectivity
between two devices. So we have to go in
the command prompt, we have to use the
command ping 2000s 1123. Suppose you want
to ping with two. So click on this, you will get reply from this. So this is the land connectivity with the IPV6 addressing. In my next class, I'm going to explain
you how to provide IPV6 addressing on routers.
So thank you so much.
4. IPv6 Address on Routers: Hello everyone. Welcome to Lecture three
or five, maybe six. In last video, we have
discussed about how to provide IPV6 addressing
on the end devices, and we have already
configured about PCs with the IPV6 addressing. Now it's time to
start working on router also because
already we have given the gateway and gateway is the exit point of any network. So for that practical, I have to use a router there. So I'm going to use 18412
routers and also am going to use one switch and two
pieces for another network. In this network, I have used 2001123 double colon
slash 96 network. So in my next network
I'm going to use to those and 1124 network. And also if you want to
connect router to router, I'm going to use
here 192168, sorry, 2001 one twenty one twenty five. So you can check we have
three different networks. So again, we have to
connect switch with the PCs and also switch
with the router. Here you have an
option if you want to connect router to
router with CTL port, then you have to add
HW IC2 teapot here. But we have only two routers. So I'm easily going
to connect it with cross cable with Fast
Ethernet 0 by one port. Here I'm going to provide
IPV6 address to another PC. One grantee for 1962001, gateway will be the 100. So I'm going to copy the gateway because it
will help me to put up in another 124
double colon to 96, one twenty four hundred. So it is the time to
configure the router because we have already
given the gateway, as well as we have
provided IP addresses. Let's click on my first router. Go to CLI. And now you can check you will It will continue with the configuration
dialog yes and no. So you have to put a note. First command is enabled
configuration terminal. Now I'm going to provide the IP address to
my fast Ethernet 0 by 0 interface f is 0 by 0. Ipv6 address 2001123,
double colon 100 slash 96. So this is the criteria to
provide the IPV6 address. While in IPV4 address, we are provided
with a subnet mask. So no shirt and exit. Now you can check the
link is going to be up. Again, I'm going to provide
IPV6 address to have 0 by one IPV6 address, 2001125, double
colon one slash 96. No shut down will be there. But the link will
not be up because on the other side we have two no shutdown command
used on my second router. So to save this command, I'm going to use do right? And if you want to provide
IPV6 routing in future, then you have to use command
IPV6 unicast routing. But that we will cover in my
next class because I'm going to use IPV6 aesthetic
routing also embeds. Let's move on to second router. Continue with
configuration dialog, no, unable config interface. Fast Ethernet, 0 slash 0. That will be connected
with switch IPV6 address 2001124 double
colon 100 slash 96. Because that will be the
gateway for these two pieces. And interface f is 0 by one. Ipv6 address, 2001125
double colon two, because on the other hand, we have given one
address and no shirt. When you put no
shutdown command, you will check all the links of routers will be
the green links. So now they are connected
with each other. If you want to ping, you can
use this message box also. You can think this
with this also. But if you try to ping this
network with another network, it will not be possible
because we have not provided IPV6 routing here. So in my next video, I'm going to let you
know about how to provide route in
IPV6 addressing. Thank you so much.
5. IPv6 Routing: Hello everyone,
Welcome to the lecture of IPV6, static routing. In my last video, I have provided IPV6
addresses to the end devices, as well as we have provided
IPV6 on the router. But now it's time to connect these routers with
another network. So that's what I'm going
to explain you about static routing in IPV6
address with the next row. So for that I have to check, Show IPV6 route command on my
router because I wanted to check what are my direct
routes, IPV6 rules. So in this you can
check the C is showing that your 2001123 is
your direct network, is showing that this is your local address
on your router. Like what is the IP address
you have provided on this? And same as C stands for connected root and
L stands for local. Now, in IPV6 traffic routing, we have to use indirect network. So if 1231 Twenty-five
is my direct network, so I have only one network here, 2001124, which is
going to be indirect. I have to click on router. First of all, to
start the routing, I have to use command IPV6, unicast routing because there are so many routers on wage. Ipv6 addressing is disabled. Ipv6 routing is disabled. Actually, I have to
enable the IPV6 routings. That's why I have used the
command IPV6 unicast routing. So after that I have to use
that command IPV6 route. Now my indirect prefixes, 2000s, 1124, double colon slash 96. Now I want to use next
hope IPV6 address. So this is my IPV6
address on F 0 by one is 2125 double colon one. So that's why my next
to or IPV6 addresses 2001125 double colon two. So I have given the IPV6 route. Again, I'm going to
use Show IPV6 route. Here. Static route is showing
that if you want to go to this network than Y or
this part, you can go. Again, same process we have
to implement on Router two. Now you want to check that
how many direct network, so we have to direct network
124 and one-to-five. But 123 network is not
my direct network, so I have to
implement a route for 2001123 double colon
slash 96, okay? So IPV6 unicast routing is going to be enabled
on router two, IPV6 route 2001123, double
colon slash 96 space. Now we have to implement
the next hole. Here. From here we have an extra
4125 double colon, one. Show IPV6 route here. You can check the static route. And if you go to the deck
stop command prompt and tried to pin 2001124 double colon one. Then you can check to you, you will get the
reply from what 241. One important thing
that we have to be notice there that an IPV4, when we do routing, then the first packet is failed. But in IPV6, there is
no failure of packets. So it's all about IPV6. I hope you understand
all the concepts of providing IP address
on n devices router, as well as the routing also. So thank you so much. This is the end of IPV6 lecture.
