Here doing and welcome back now in today's video, we will be discussing about the dual stack IP address
date for the LBC.
Now do note that the elastic load balancer supports two primary entries state.
First one is the IPV four and second one is their dual stack.
Now, when we're discussing about dual stack, it means that LV supports both the IPv4 and the IPv6
places.
So considering that you have, let's consider that you have an LP that is available and you have enabled
the dual stack IP address type so that users can go ahead and connect to the LP both on the IPV foot
as well as the IPv6 addresses.
So this is the basics on that.
Let's go ahead and have a quick demo.
Now, currently I have two albee's that are available.
First one is based on the IPB four address.
The second one is based on their dual stack.
Now, before we go ahead and look into it in detail, let me quickly show you where do you see those
options?
So whenever you go ahead and create an application load balancer within you, you have an IP address
state and you have IP full as well as dual stack.
So this is where you can go then selected.
So let's go back now.
First, let's exclude the APB for so you have the DNS name here.
Let's copy the dynasty and within the command prompt.
Let's do it.
And this lookup on this DNS and indeed is once you get the single APB for a Brazoria in a similar way.
Let's go ahead and copy the DNS associated with the dual stack based AIB.
Let's do a nslookup.
And now you see, you've got both the public IPV foot and the HPV six entries.
Great.
So I hope with this you understood the basics of dual stack based IP address support.
Now, before we conclude, let's go ahead and look into how we can enable this because there are certain
ID business steps that are required.
You cannot directly just create the load balancer with dual stack.
So let me go ahead and go to a random region where we have not really explored things now within yet.
Let's first create a target group will quickly create a target group based on IP address.
Let's call it as a IPv4 Haven DG.
Let's do a next.
And in the IPv4, I just specify our internal IP and let's create a target group.
All right.
Now, once their target group is created, let's go to the load balancer.
Let's create a new application load balancer.
Let's call it as the more stack and within you.
You have IP address type default of IP foot.
You can also go ahead and select the dual stack.
Now within, you can go ahead and also select the availability zones.
And as soon as you create a load balancer, immediately you get an error stating that the selected subnet
must have a C++ block required by the IP address state.
So any subnet in which you are associating the load balancer with that subject must have IPV six eight
bit.
So the first step whenever you are applying for the dual stack based IP address state is that the subnet
must have IPv6.
So let's go ahead and enable IPv6.
So let's go to our BBC.
First thing we'll have to enable the IPv6 for WI B.C., so we'll do, added Kadia.
And we'll add a new IPv6 ID earlier.
And the option that we'll be using is Amazon pro-rated Abdulkadir.
Perfect.
So the carrier is associated and within the BBC control.
You should also see you have IPV four and the IPv6 C++ block.
That is great.
The next step is you also have to associated either subnet level.
So what will you be doing for subnet in the availability zone and the availability Zone C will be associating
a C++ block of IPv6.
So let's go ahead and did the IPv6 ID here.
Let's add IPv6.
We'll just call it as zero one.
You will save it.
Perfect.
Let's do a similar approach for the next subnet.
Let's specify zero two and will do a sieve.
Perfect.
Now both of these subnet, you see, they have associated IPv6 year now with any load balancer.
Let's refresh this and further subnet 1b and this subnet 1c Soviet India IPv6, you see, it basically
has this message.
However, if you select one D as well, this will not work because there is no IPv6 associated with
this subnet once.
Then you can go ahead and specify the target group and let's create a load balancing.
Let's click on view.
Great.
So our e-mail is created and it is still in the provisioning stage.
So if incompetently nested, and let's do a nice look up on this DNS and you do not really get a response.
It might take a little time since it is in the provisioning state, so it will take time.
Let's go ahead and discuss about some of the important pointers.
So the first important point is that to use the IPv6 addresses the BBC when you launch, your ESB must
have a subnet Savitt associated IPv6 data blocks.
This is something that we have already seen.
Second is that the IPv6 addresses can be associated only with the internet facing LBC and any lebese.
You cannot have an internal application load balancer, plastic load balancer and the network load balancer
that can have a IPv6 entry, so the internal based configuration is not really supported.
So let's go ahead and refresh.
The state by state is active now.
And from this, let's do it and look up again.
And now you see you are getting what they are IPv6 and the IP for addresses.
Great.
So I hope with this you understood the basics of dual stack based IP address types support.
Again, if you're using Load Balancer, make sure you delete it, otherwise you'll be charged at the
end of the month.
So with this will conclude today's video.
