So in this video, we're going to work on our Gateway Zero,
this guy right there, and configure it to work with OSPF.
So we're going to use area zero,
so we'll go ahead and define area zero in
the configuration for our tier zero gateway.
Then we'll specify that the interfaces that this gateway is using as it
connects to this external segment which is being provided by Edge 1 and Edge 2,
we'll specify that we want both of those interfaces participating in OSPF area
zero.
So here in the NSX Manager, to do that,
we'll click here on the networking tab.
And then on the left, let's just take a peek at our network topology to make WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
And then on the left, let's just take a peek at our network topology to make
sure it hasn't changed.
No, it hasn't, fantastic.
And let's go configure our tier zero gateway and enable it for OSPF.
So to do that, with networking still selected on the left hand side and our
connectivity,
we'll click here on tier zero gateways.
And here for our tier zero gateway, we can expand it before we start to edit.
If we go to OSPF currently, OSPF is disabled.
So let's go ahead and configure it by going to the three dots for our tier zero
gateway
and from the sub menu clicking on edit.
From here, we'll scroll down and we'll go down to OSPF and we want to, first of WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
From here, we'll scroll down and we'll go down to OSPF and we want to, first of
all, enable it.
So we'll go ahead and click on the slider there to enable OSPF.
We also want to set up an area zero.
So here in the OSPF section, over on the right, it says area definition.
And we'll click here so we can go ahead and set up an area.
And what we want to do is set up area zero.
So there's no area definitions found.
And all we need is area zero.
So we'll create it by clicking right here on add area definition.
And then we'll enter the area ID.
I'm going to put in four zeros, which effectively means area zero, the backbone WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
I'm going to put in four zeros, which effectively means area zero, the backbone
area.
So I'm going to leave everything else at their default and then click on safe.
So now we have an area called area zero and we'll click on close.
And now that we have that area and here there's a one there where it says area
definition,
we can now go ahead and specify which interfaces that we want to participate in
that area.
So to do that, what we're going to do is go down here still in the OSPF section
and
go down to OSPF configured interfaces.
And here we're going to click on set. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
And here we're going to click on set.
So we'll click on set.
And currently there's no interfaces participating in OSPF.
So we'll click here on configure interface.
So for the first one, we're going to go ahead and specify edge one.
And for the area, we're going to specify area zero.
So effectively, that means that this logical interface on our tier zero gateway
using edge
one and the IP address dot 61, we want it to be included as part of area zero.
And then we'll leave all the other settings at their defaults and click on safe
.
Then over here, it says in progress, we'll go ahead and we'll click on refresh
there.
That looks good. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
That looks good.
And while we're at it, let's also add the other interface provided by edge two.
And that way, if there's a failover situation, let's add the other logical
interface, which
is being provided by edge two.
So we'll click on configure interface one more time.
And this time we'll select edge two at dot 62.
It's going to be in the same exact area and all the other parameters and leave
at their
default and click on save.
Fantastic.
So go ahead and click on refresh there.
That looks good.
Let me scootch this over a little bit.
So we have the two interfaces, both an area zero network type broadcast. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
So we have the two interfaces, both an area zero network type broadcast.
OSPF is enabled on both of them.
Fantastic.
We'll click on close.
So just as a confirmation here, it shows us two interfaces configured for OSPF
and we'll
click on safe.
All right, then we'll scroll down and click on close editing.
And then we'll collapse that.
So now if we wanted to come in and say, okay, have we formed any OSPF adjac
encies with
any other OSPF speakers, what we could do is we could expand this.
This is our tier zero gateway.
Scroll down to the OSPF section.
If it's collapsed, go ahead and expand it. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
If it's collapsed, go ahead and expand it.
So here in the OSPF section, where it says OSPF neighbors, there's a hyperlink
for view.
And if we click right here on view, it'll show us any existing OSPF neighbors.
And it'll also show us the state.
So we have full adjacencies.
It should reflect that as well.
So we'll go ahead and click on view and check it out.
We have two OSPF neighbors, but we are in the two way state.
And the reason for that is look at the two neighbors.
We are basically peering with each other.
This is edge one, peering with edge two and edge two, peering with edge one. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
This is edge one, peering with edge two and edge two, peering with edge one.
However, they are not going into a fully adjacent state.
And that is because neither one of them is willing to be a designated router.
And that's why they stopped right there.
So once we add on our external router and enable OSPF there, then while a
situation
where both edges will become fully adjacent with that external router.
So currently it looks like this.
Here's our network segment.
They're both connected.
So there's edge one and edge two.
This one's a dot 61.
This one's a dot 62. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
This one's a dot 62.
They see each other, but because neither one is willing to be the designated
router or
the backup designated router, they are not forming a full adjacency with each
other.
So our next step is to go ahead and take our external router.
We'll go ahead and call R1 just for this purposes here, which is a dot one.
Enable it for OSPF.
And when we do, we should have full adjacencies between edge one and R1 and
full adjacencies
between edge two and R1.
At which point, once we have the adjacencies in place, we can then proceed to
start advertising
and learning about routing information from each other. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
and learning about routing information from each other.
So our next logical step is going to be right here.
And that is to go ahead and prepare the physical environment, make sure we have
OSPF enabled
here.
And we'll do that in the very next video.
So I'll see you there in just a moment.
