So for our VRF light game plan, let's do the following.
Let's implement this topology with two VRFs,
one for customer blue, one for customer green,
including the use of tier one gateways for each of those
and segments for each of those customers as well.
So as part of that, we're going to need to clean up
our existing topology.
And then once it's all cleaned up from scratch,
we need to go ahead and deploy our tier zero gateway.
And that's this one right here.
So that has to be in place.
We also need to associate it with uplinks to talk to the WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
We also need to associate it with uplinks to talk to the
external routed environment.
And then once we have that in place, we can then go ahead
and start carving out individual VRFs for the additional
customers that we have.
So in our example, we're going to use two customers,
the blue customer and the green customer.
So for the T zero deployment, let's use an external segment
with VLAN 21.
And so on that segment, that external segment,
we're going to use 10 dot 21 dot zero dot zero
with a 24-bit mask.
And then for the two edge nodes that will incorporate
on that subnet, let's go ahead and use edge one at dot 61 WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
on that subnet, let's go ahead and use edge one at dot 61
and edge two at dot 62.
So once we have our T zero in place, we can then go ahead
and create a T zero VRF and we'll start off with blue.
So our next step will be to deploy the blue VRF.
And for that one, for its connectivity up to the external
network to the edge router, we're going to use VLAN 23
and its IP dressing space is 23 dot 1 dot 2 dot zero
with a 24-bit mask.
And the default gateway up there is at dot 1.
And once again, for edge one, we'll use dot 61 WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
And once again, for edge one, we'll use dot 61
and for edge two, we'll use dot 62.
And for simplicity, we're just putting one external router
out here, but this would represent, for example,
a top of rack router.
And so in the production environment for fault tolerance,
we'd have one of our edges go to one of our top of rack routers
and the other edge going to the second router.
But again, for simplicity, I'm just putting one external router
out here to save us a bit of time during the configuration.
So then once we have this blue VRF in place,
we can then go ahead and create our blue tier one gateway.
So that'll be right here.
So once that's in place, we can create our segment WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
So once that's in place, we can create our segment
and then finally go ahead and test.
So here's what I propose we do.
We'll do all these step by step for the benefit of getting
the initial tier zero gateway up and running
and the blue VRF and the blue tier one and the network segment here.
And then once we do all of that, it's simply a repeat process
for doing it once again for our second VRF,
which is going to be the green VRF.
So effectively, we just logically repeat this process.
So for the green VRF, the only difference would be
instead of using VLAN 23 is we're going to be using over here
for blue. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
for blue.
Let's use VLAN 24 over here for the green.
And then for the tier zero gateway, we're going to be using VLAN 21.
So for the blue customer, let me go ahead and put this as 23.1.2.0
with a 24-bit mask.
And when we get to green for the VLAN 24 connection,
that'll be 24.1.2.0 with a 24-bit mask.
And in all cases, the external router on those three VLANs is at dot one.
And it just occurred to me that if we go through all this for blue
and then we also as validation do it again for green,
that might take quite a bit of time. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
that might take quite a bit of time.
So as a preemptive step, I'm going to go ahead and off camera.
I'm going to simply remove all of our existing tier zero and tier one
gateways that we currently have.
So I'll take care of that on my own.
So our next logical step together then would be as part of our game plan
to go ahead and start the initial deployment of our tier zero gateway.
And we'll do that in the next video.
