In this session we are going to discuss about Edge routing capability or tier routing capability.
Plus I will log in while the Seelye to the edge devices.
And I will show you a few of the CLIA useful commands.
Here you can see that NSX supports static and dynamic routing protocol and dynamic no BGP is the standard
so everywhere you will see that BGP has been used inside the data center selecting a zero they are using
the static and BGP protocol.
Both IP before an IP resets workload.
In addition to that Tier 0 Gateway they are supporting ie BGP as well so not only they are supporting
BGP but they are creating IBP us as well.
We have certain use cases we will see that why they are doing this.
Tier one gateway supports a static road but they are not supporting dynamic or out at the moment.
All right.
So knowing this thing will go and log into the device and will find all these things I have two three
slides.
Let me quickly go through that and we'll see that.
What type of BGP support it has in Tier 0 so BGP is the de facto protocol on the van.
Any modern data centers.
A typical leave us find topology uses BGP so you can move your encapsulated packet inside BGP from one
place to other place right means you can create an in between.
Or you may have set this media replication link that is running BGP.
There are so many use cases for BGP and Cisco BGP users some I guess family call BGP VPN and according
to the act they are sharing their data center load across multiple centers BGP is one of the standard
because it has so many I families to support and it's really extensible protocol now Tier 8 we support
a BGP and I BGP on the external interfaces with physical load.
One important thing to note here is that BFG by the original forward detection can be enable by BGP
to check BGP link status so that's important thing we have and be a BFD nowadays it's become very advanced
and it has really fast means it is sending fast help addicts just to check the BGP is straight and here
you can see that bare metal edge support minimum of 300 milliseconds 3x addicts.
B B if to keep alive evidence that this is one third of a second and the VM form factor the virtual
appliances they are supporting one millisecond thousand millisecond when one second of keep alive.
B Every time we told our tribe and its experiences what type of BGP supports are there they can see
that the BGP support has to unfold right.
Ace no EVP Michael hop support I BGP EVP is Mikey hop BFG ICMP BGP allow is in BGP road aggregation
route redistribution in BGP.
So here we can see a long list of BGP configuration and support is there not really true not only the
I BGP and BGP is ECM PNB inside DAC but we can do some sort of inbound outbound filtering we can influence
the routes so we have the BGP path selection criteria with weird local preference is path prepared mega
etc. there support in large community list visible well known communities they are supporting.
So here you can see that they're supporting all sort of BGP features and by the end of this you can
see that the NSX supports Chris will restart and BGP.
So what I'm going to do now that as per our diagram so how our diagram looks like at the moment we haven't
configured ECM P but in a lab section in the upcoming session we are going to configure the ECM P and
we'll see that multiple BGP parts as well.
At the moment our lab topology is like this we have zero connect to outside and it'd be in between T
Zero we have DC 21 in and a chain link and that IP something hundred yards sixty four da execs we have
the default road towards zero here the TS 0 and outside we have BGP running and the interfaces and the
IP address assigned here is say the one ninety two one six eight hundred da da three here and one here.
So what I'm going to do now that I will go log into the IT device each node and from that edge node
I'm going to show you the BGP configuration and some of the basic configuration over the interface as
well highlight select me go and quickly log in to the edge node.
So here you can see that I logged into the edge node and what will be the first command I want to run
here is that I can go and check the logical doubters.
So here also if you type tapped I would tell you that it's the next option you have here you can see
that I have we inside query of Inside Edge one I have one is our Tier 0 Gateway 0 1 means is key years
all I have is are India and inside Tier 1 I have the OK so at the moment I want to see the interfaces
or all these is are and they are.
So for that what we need to do we have to check the VRA.
So suppose this is belonging to be an EF 0 this first one.
This guy here.
So once we go inside we are off.
Then you can go and check get interface and then you have option.
Let me show you what options you have here.
This final option you can find the.
So first of all let me show you get into office and then I'll show you the freedom so you can see that
there are so many interfaces.
And what I can do here that I can find with the name.
So let's see that what name you have.
So here you can see that we have named here zero Gateway 0 1 Tier 1 Gateway.
This is something like the interface between between Tier 0 and Tier 1 correct.
So in between two notice then he does he have BP the airport.
You can see you have BP is our port uplink one is our internal routing etc..
So let me do one thing let me quickly find IP as well.
So if we check the IP now you can see that 164 is nothing but digital and tier one interface.
Then you have 1 6 9.
We know that these are internally used by the system.
Feel the interfaces are the interconnection link between the.
And so those 1 6 9 1 6 9.
Then you can see that I have an uplink whose IP is this.
So over this particular uplink we have BGP configured correct.
So now if I want to go and check the BGP neighbor I can go and quickly check.
Sure.
BGP and then neighbor and then somebody.
So here you can see that this particular IP is my fear with this particular IP the other is number that
we are seeing here.
We'll check this later.
But this is the BGP my is is 6 5 0 0 1 and remote is is 6 5 0 0 2.
All right.
So what we can do now that we can go and check BGP related other commands if you want to check.
So you can see the labor.
And if we want to see the neighbor in detail you can then this command.
So here you can see that.
Let me show you this configuration because this is something that we are interested to BGP neighbor
is this IP.
This is my neighbor I because my IP is docked three remote is is this local is I am in this particular
is this is the remote is my mile out.
This is a remote router.
But my notoriety is this.
This is the IP over the uplink.
So you can clearly see this BGP configuration and the interface configuration.
And the point here was that it is fully supporting this configuration of BGP even if instructed road
will be there.
We can see that.
So now if I go and show you say for example you get the notes
and enter you can see multiple roads like this is you connected to you and see connected and then you
have the lizard on their top all the different type of approach that is supporting his.
All right.
And then finally again we'll go back and check the logical routing.
So get logical routing so I can go and check the other we are off.
So now we have we went inside.
This is our.
And we check the BGP configuration and interfaces.
Let me go and connect with giardia 0 8 to 1.
That is the view one.
And here if I go and type get interfaces so you can see there what interfaces it has and then we'll
find it.
Name so here we can see you have these interfaces the same interfaces because they belong to same IP
subnet.
So this this is okay.
We can see the same thing here.
But if you go to the tier one edge so let me show you.
Go get internet.
Logical and helped us.
So now if you go inside the V area of that is we are three and that is the tier 1 gateway.
And now here if we check show not sure who is the Cisco command kicked out so we'll see.
And then I would say you can see that it is not actually connected with the real refs will do one thing
will it logical.
Let's see there what options we have so he can see have great neighbor stats and all those things.
I will show you all all these options that we have to first of all what I want to show you here is that
I want to show you get the interfaces and the find the name
find the name.
Let's see what interfaces it has.
Now here you can see that you have interfaces connected with logical switch.
So here you can see Web D.B. app correct.
One link that is going to the uplink and one link that is connected with the Acer.
That is the intra link you have.
So what I can do here that I can find the name.
Let's see the IP as well.
So now it is clear that OK we have a web app and maybe so web IP is nothing but this.
And then you can see their GP and then you can see the app then you have the intra link.
Then you have the t 0 2 T1 connectivity so you can see all those interfaces used here in our scenario.
And now what I want to do there if you see you can see if you have any less options.
Correct.
Because it is not supporting any dynamic routing and we haven't confident in instructed rotor.
So it has only firewall option you can see a forwarding option.
The interface.
You can check whenever we can check and it we can check the stack.
So if we go and check forwarding here you can see that the forwarding table and these are the DL to
T1 interface.
These are the less interfaces logical switch interfaces that we can see light.
So this was the routing capability inside the it's devices.
We can go and log into the device itself and we can verify from there as well.
These techniques will be used if we are doing some troubleshooting because while doing the troubleshooting
the CLIA access and silly commands and treats are very useful and handy.
