So, behind the scenes, I took our existing topology and I did a major cleanup,
which basically
means I got rid of all the tier 1 and all the tier 0 gateways.
They're no longer in existence and also there are no segments anymore,
including no VLAN
back segments, no overlay segments, everything's gone.
In fact, let's take a quick peek just to verify that's the case.
So here in the NSX manager, if we click on networking at the top, here's our
network
overview and this is currently showing no tier 0 gateways, no tier 1 gateways, WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
overview and this is currently showing no tier 0 gateways, no tier 1 gateways,
no segments.
However, what I did leave in place would be scroll down and go down to
networking profiles.
I did leave a DHCP profile that we can call upon once again for DHCP services
when we
need it.
But as far as segments and gateways are concerned, if we click here in network
topology, that's
going to reveal the picture and that is there's nothing to display.
No tier 0 gateways, no tier 1 gateways and no segments.
All right, so now that we've confirmed the cleanup is done, let's go ahead and
deploy
our initial T0 gateway, which has to be in place first before we can start WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
our initial T0 gateway, which has to be in place first before we can start
carving out
parts of it for VRFs for our individual customers.
So for this deployment, we're going to go ahead and create an external VLAN
back segment
for VLAN 21.
We'll use the IP dressing space of 102100 and then for edge 1 and edge 2, we'll
use .61
and .62 respectively.
So back here in the NSX manager, we'll click on networking and with networking
selected,
we'll click on segments and let's create our external VLAN back network segment
that we're
going to use for the initial T0 gateway.
So with segment selected, we'll click on add segment. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
So with segment selected, we'll click on add segment.
I'll call this external for VLAN 21 and then I'll collapse the left hand side
here to give
us a little bit more room and for the transport zone, I'm going to go ahead and
use our existing
VLAN back transport zone and down here where it says VLAN, I'll put in VLAN 21
and with
that in place, we'll scroll down and click on safe.
It's asking us if we want to continue configuring the segment, we'll say no.
So there it is.
Next, let's go ahead and create our T0 gateway and then we'll connect using WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
Next, let's go ahead and create our T0 gateway and then we'll connect using
edge 1 and edge
2 to this external segment for VLAN 21.
So to do that here on the left, still under the networking tab, we'll go down
to tier
0 gateways and click on add gateway.
From the drop down, we're going to create our initial tier 0 and then after we
create
that tier 0, when we get over to the blue and the green VRFs, we'll choose VRFs
.
So for now, we're going to create the parent tier 0 gateway by clicking on tier
0 and let's
call this our tier 0 gateway and as far as the HA mode, let's go ahead and use
active
standby and then for the edge cluster, we'll choose our cluster that we put WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
standby and then for the edge cluster, we'll choose our cluster that we put
together earlier
and then we'll scroll down and we'll click on safe.
So now that we have this brand new tier 0 gateway saved, we can continue our
editing by
clicking on yes right here and we can configure things such as the default
route that it's
going to need as well as its interfaces.
So for this gateway, we'll scroll down to interfaces, expand that and we'll
click right
here on set and we are going to set up two interfaces, one from edge one, one
from edge
two, both connecting to the external VLAN 21 back segment. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
two, both connecting to the external VLAN 21 back segment.
So we'll click here and add interface and I'm going to call this interface edge
one
on VLAN 21 and that is going to be on the 10.21.0 network with a 61.
So we'll put that in for the IP address and then for the edge node, we'll go
ahead and
choose edge one and for the segment we're going to connect to.
This can be our external for VLAN 21 segment.
So that looks good, we'll scroll down, click on save and then while we're at it
, we'll
add one for edge two.
So we'll click on add interface to our tier 0 gateway. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
We'll call this edge two on VLAN 21 and this will have the address of 10.21.0.
62 based
on our plan with a 24-bit mask and it's also going to connect to that segment.
So again, for fault tolerance, we probably have two top of rack devices that we
can
connect to and we'd use two separate VLANs, one for each but for the demo, I'm
just going
to use the two edge nodes connected to that same external router.
And so for the edge node here, this is going to be edge two and we'll scroll
down and click
on save.
And then we'll give it a moment and make sure that both interfaces are
initialized.
Let me do a refresh right there. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
Let me do a refresh right there.
That looks good and we'll click on close.
So there's our interfaces and let's go ahead and close editing.
So now with our tier 0 gateway in place, if we click here on network topology,
again
with the network tab on top and on the left, network topology, now we have our
tier 0
gateway with two interfaces, one provided by each edge and we can go ahead and
double
click and it'll show us that as well.
So here's the fabric view with edge one, which is active and edge two, which is
the
standby.
So we click back there.
So now that we have the tier 0 gateway deployed, that's this one right here WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
So now that we have the tier 0 gateway deployed, that's this one right here
with its connection
to the external environment and it's using edge one and edge two behind the
scenes to
do that.
So our next logical step is right here.
We're going to take that tier 0 gateway and we're going to carve up a portion
of it as
a VRF to be used by this customer here on the left and we're going to call that
customer
blue for this example and that'll keep all the routes for blue separate in a
separate
VRF that's represented here by this logical blue VRF router icon.
It'll keep all those routes for blue that customer separate from all the routes WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
It'll keep all those routes for blue that customer separate from all the routes
over
here in green, which will be in a different VRF.
So join me in the next video as we begin the configuration of our blue VRF
right here.
