Now we have a lab for high ability.
So let me go and log to NSX manager and then I will log into the various SBB ISIS as well.
And let me perform this task.
Now I logged in inside the NSX manager.
You can see I can go to the networking here you can see that we have 2 Zero gateway.
Now this key zero Gateway having a more active active clearly you can see it is linked with one of the
gateway that you can see link tier one gateway.
Now let me quickly go here and click Edit So here you can see clearly that this T Zero Gateway is active
active and it's part of a cluster because it is close to zero 1.
So first of all in this cluster we have some devices we have actually to its devices.
So let's do this take let's go to the system and the
let me go to the fabric and the nodes in the north section you can see that you have age cluster and
we have clusters zero one inside that if you go and check you have to Edge Edge one and it's 2 like
that in say cluster 2 we have age 3 and age 4.
Now if I go and log into the edge devices for example I will log in to age 1 and age 2.
Let me quickly show you that what is initiated or what services are initiated there so let me log in
this
this we have seen in the last few lab
and what you can do first of all you can go and check and get a logical dose here clearly can see that
you have is out and you have D are related to to your 0 now and go to other age that is age number two.
And let me go here heads up and I log in here as well.
And we'll also we'll see that two armed services are initiated
and let me go in first.
Let me log in and let's set up this command.
That is the logical logical hero to us right.
So here you can see the thing is initiated.
Now we have to go and initiate this.
So what I'm going to do as for our topology if you reflect upon the diagram and find that you have two
tier architecture and inside these 0 0 is part of cluster where I have to it's device I am going to
show you that uplink A is actually map with NSX edge one and I am going to create one new uplink that
is uplink B and I will map that to new uplink with a two and since they they are in active active mode
so they will function as the active active mode they will perform some sort of testing as well.
But let me go to the transport.
Let me go to the networking and let me configure this uplink inside one of the and connect with one
of the other NSX.
Correct.
So let's go back to the networking.
And here we are.
We'll go to it
that's OK this conflagration is okay will go to the interface.
And this guy here will add one more.
This time I'll go and add a link.
So for example B this is external IPL give 1 9 2 2 1 6 8 1 underdog for 24.
And in Barton We can clearly see that this is one of the uplink.
If I expand this you can see this is attached NSX is 0 1.
First of all this is the uplink.
And then the node is 0 2 and the rest of the things we can leave it and it is initiated on initialized
initiated no initialized close this and close the editing.
Now if I go back to the number two and if you see no logical devices here you can see now it is initiated
I am basically looking for the interface that is related to service interface.
So here you can see distributed cell services we are of six.
So now what I can do here.
I can go and connect with this millions of and
so is not we are as the screen is up bang down means the have nots.
Emergency properly.
Let me stretch it and let's see the logical notice.
We are fighting for as are is two correct.
So we are EF 2 and then we can go and check the interfaces so first of all I want to check the interfaces
and then we can do find name here we can see the uplink.
Me and then what we can do that we can check the IP you can see the IP as well.
Great.
Now if I check the BGP neighbor and somebody
and here you can see this is up from last one minute 30 seconds and this is internal IBD.
Computer again will let me go ahead and show you this thing also.
If I go here and check.
So for example first of all I want to go inside the cerebral sphere if that is the of same zero and
if you do get BGP neighbors and then somebody so we can see this summary otherwise we have the long
output.
Now in the summary you can see that we have one interlink 1 6 9 2 5 4 and that is established in between
two devices and that these things are actually covered initially so they will form some sort of eye
BGP in between them.
So two devices now they have the IGT relationship and those roads because now they are in the active
active mode right.
So since they are in the active active mode and the logic is that you can refer to the previous topology
and diagrams as well.
But let me draw here.
So we have uplink one uplink to going to outside but in-between you have a BGP automatically created.
I haven't done anything for a BGP with these IP addresses and since this is active active so they will
update their information to both databases now to verify this active active relationship what I want
to do here that I will go and shut down the edge.
So if I shut down so logically this to zero is connected with T1 and this T1 having a logical segment
or the logical switch.
So one two three web app and TB.
So that means if this device is down it's still be sure to have IBC appear with this because they are
in active active and the Catholic should go correct.
So let's do this activity while doing this activity.
What I can do that I can go and open the command prompt.
I need one of the one IP of one of the VM.
So let me quickly go and check that so I can go here.
And they can check the
William IP so so for example.
Let's check the Web.
0 0 1.
You can see when I get to.
Oh sorry 172 ones extend out eleven and now or take a do here.
Is that true.
I can go here.
I can bring to this IP first of all let's see that we have literally two or not turned out eleven minus
D the Infinite Being we have all right.
So what I will do here that I have the it's one I will go here and I will make this power
off
yes.
Now you have done the power off and we are doing the big test.
You can see this this came out on top also you can see the timing 29 26 that time what is going on will
see that how much time it will take to kick the convergence
because what is happening here is we do not have issue with the t 0 and the NSX is now we have the issue
with the BGP re convergence and by default BGP hold down time it is for three minutes.
So what will happen that they hold on till the whole time will expire.
It will wait and on the top you can see the Times Waterloo meanwhile I'll pass the recording and was
will get this been back up I will resume that so let me pause the recording so it still we we are seeing
that nothing is happening if I go back to the number two and I can see this link is also become active
and if I go back here to s number one
and will see their towards their status is this is down so we can do anything with this
so clearly you see this is down at the moment and the
will wait behind the scene to see now you can see Bing has come back so it was down and on the top you
can see the timers as well that is is still going on but you can see that Bing is back and that that
was the testing actually I was looking to do so now I can see this active active and the feel down and
uptime also you can see now that you can see that the establishment here some of the APIs are useful
some other purpose but now it is Chablis and here we can see the ping is back.
