In this section we are going to discuss about VM edge.
Note that is virtual age node and the edge cluster.
Now this virtual form factor that we have we can install the audio file the we have and I use all images
that the first thing and it is widely supported over VM where hypervisor attacked the E6 I know we have
various interfaces.
I will log into the device and I'll show you all these interfaces but it zero is used for management
and other interfaces can be used as a as a connectivity with the uplink of physical interfaces or they
can use as an overlay interfaces to form their caps correct.
They are using the DPRK fast but so we have seen this in the previous section previous to previous section
data.
They have the feature of TPP decay fast but apart from that that these interfaces that are located to
the external.
So clearly it is mentioned that it can be used for external.
It can be used for overlay as well So point number four clearly saying that field the interfaces related
to a fifth spot you can assign to the overlay field the interfaces you can assign as a uplink.
One of the physical interfaces used as a management interface.
Now it is simplifying the overall architecture of invidious and we have seen this in the previous elections
that the use of invidious or what anybody else is doing that defines how the entry is balanced traffic
across the uplink.
This default teeming policy can override for RI lan segments 1 Li using name gaming policy.
These things actually we have discussed earlier you can refer those videos where we have seen these
things then to develop desired connectivity that is explicit availability and the traffic engineering
more than one in we for edge maybe required now in two point four and onwards.
The more and more information is happening to reduce the number of in video.
So probably one in which this will so will work as a Distributed Common switch among among the compute
node
each can reduce instances can have a unique teaming policy.
So if you have a different end with yes.
So for example for as devices or compute devices at that time all the energy is having their own deeming
policy but again 2.5 onwards much more innovations are going on to have common and we use for compute
and energy is for is to ISIS now age cluster.
This also we have seen in the previous lab sections that multiple devices can be grouped inside each
cluster.
Now the nice thing here we will see that you can think this age cluster for a moment as a container
and inside the continental Europe putting many global instances of age node it will select what they
use and the capability here and is cluster is a group of H transport node.
It provides a scale out to Reagan and how to put Gateway functionality X through scale out from the
logical network to the edge node is achieved using the easy MP.
We have actually done the lab for higher ability and ECM B in the previous section and is X to introduce
the support for heterogeneous age nodes which facilitate easy migration from each node.
We aim to build metal as you note you can mix.
You may have it related to VM you may have physical age no to both the virtual and the physical form
factors are supported in terms of age node.
There is flexibility in assigning Tier 0 and tier one or tier one gateway to the age nodes and cluster.
So let me show you that what flexibility we have when we are assigning t 0 T1 inside the cluster.
So one type of cluster you can see that you have the edge node one edge Node 2 and is no 3.
These are as nodes inside one is node you have two years zero you have Tier 1.
So one instance of Tier 0 2 instance of Tier 1.
Likewise you have 3 different age node.
So that's one of the with that killer clustering so basically clustering the edge node but inside the
edge node you have multiple instances related to your zero Tier One now depending upon the service node
services hosted on the edge node and their uses and each cluster could be decided simply for running
centralized services.
Yes age nodes we know this thing that they have the NSL the like that they have they can do both now
in the next diagram you'll see that.
Not only that we have the Tier 2 and Tier 1 architecture in your grouping them.
But if you want you can group the age node like this also.
So one of these is node having quality is 0.
Other group of nodes they have Tier 1 Tier 1 0.
So this type of grouping is also possible inside the clusters.
So mix and match single single grouping everything is actually possible.
And there can be no this this is actually very very important.
Summary type of slide select machines the colour of the marker.
And here you can see that there can be only one Tier 0 gatekeeper is not however multiple tier get we
can be hosted on the edge node so you may have one you may have multiple let's not this thing is easy
and straightforward with know this thing.
Now you can see the limit a maximum of ten is n can be grouped in each cluster so can the max limit
is 10 edge a year as you look great with support.
Maximum eight.
Equal cost multi parcel.
Then we are doing the easy ENP at that time they are supporting it links are the equal cost multiple
multi putting option we have now.
The other really important thing here you can see is that is node in an age cluster runs a B T by the
original forward detection on both general and management network to data mine the edge node health
and the failure capability.
So we have B of the two different form of we have d we have in the virtual node they have one second
and three seconds of timer but in case of physical devices their timer is less that maybe 300 milliseconds
one third of second then 90 millisecond.
So B FTE protocol is running there and be a protocol is running the to provide the fast detection of
failure for forwarding part all forwarding injured and it is improving the convergence.
So what next.
I'm going to do here I am going to log into the one of the edge node and I want to show you the interfaces
and then the cluster information.
So let me go and log in to one of the node like I'm inside one off the edge and first of all I want
to show you the interfaces and the name if I can get the name of the interface our maybe it each.
Let's see.
So multiple ways we have that we can go and find the interface if you want to do the exact search here
you can go and find with the interface we can see that we have it has zero interface that will be obviously
for management purpose.
And here you can see that inside eat zero.
You have the broadcast a broadcast.
Agnes Burt actually I was I am actually looking for the management IP so I do one thing I'll go ahead
and put it in cap.
But clearly you can see that you have all the fast but interfaces few of the differences maybe use for
the overlay field maybe use to connect the external interfaces once we do that.
Next I want to show you the information of the cluster.
So let me go and run that gate and then cluster.
You can see there you should have the information of the edge cluster so you should go and check like
this.
Kick its cluster.
And do we have option here.
And we have two options One is the status one is the history.
So I will call and show you the status first.
This area is great as you can see their higher abilities up and do have ability is great as is active.
Do we have a showing here in this.
I don't see.
Let's see.
Let's leave this one below.
There is no idea you can see the administrators the configuration apply the agency the be 50 one second
and three second because this is the virtual phone back to maximum hops the data part is up the services
are up the health check up here you can see that interface and here you can see the DP tepees use inside
fast part it zero.
So he is my tip interface this is my management interface and overall the status of cluster is up and
running OK so it is the way that you can log into the device and you can verify the configuration.
