Hello everybody.
Welcome to our single area or SPF configuration.
Lap This is gonna be a real fantastic session.
We are gonna live.
We are gonna learn lots of new things.
We are going to learn how to configure or SPF and we are going to provide dynamic routing communication
between the end devices too.
So let's go.
We have three steps that we should do.
The first step is all interface conflicts are made before coming for your single area or SPF area zero
between all rounders to provide food connectivity between all pieces in network.
Pretty cool as you can see that in the figure we have four others connected to each other.
But the question is saying that all interface conflicts are made before.
That's a good news guys.
That means Hey dude you're a professional anymore.
You don't need to configure an interface you know it's already OK.
I know that you can do it anymore.
That's pretty simple for you guys.
All right this second one show IP protocols and show ip route commands and check the output good and
three room show IP SPF and show IP or SPF neighbors commands.
And check the out of Troy IP SPF database.
Okay let's go as you can see it.
Let's talk about the topology some first rather one is connected to two and three and to the left of
them for a one allow 1 0 segment what I'm going to do is I'm going to configure Rather's four or SPF
routing to do it.
I'm gonna check the interfaces network ideas that rudders are connected to.
Then I'm going to advertise that network to my neighbors and I'm going to provide full connectivity
between four Rather's and then four pieces also there's gonna be a really really cool session.
And let's start with the first step.
Okay.
All interface conflicts are made before calling for your single or else.
Between all Rather's to provide full connectivity I'm starting with rather why here is my pay cut.
Trace sir let's go with their rather warm first
enable but I'm going to show you that we're rather one is connected first.
Rather one is connected to three different networks.
As you can see that it's
yellow and that zero network it's the wealth that zero network and it's third in that zero network.
But while making my SPF configuration you don't really memorize you don't really need to memorize this.
We have a command which is showing us which interfaces are related to which networks and we are going
to advertise that networks.
OK watch me first.
I'm in the CLIA and I'm running show IP in their phase.
Brief comment as you can see that our Jaeger 0 0 interface has an IP address of eleven that one and
the others are 211 13 that one because of I'm using a sledge to any force having them mask with this
my network I.D. are Teyla eleven that zero twelve that zero and in the Zero all right let's go county
and rather or SPF I need to define a process I first this process I.D. must match on for Rather's two
for exchanging or SPF roots rather as before I can change an arbitrary thing I'm going to use one rather
was being far the first thing I should do when configuring or SPF is defining the rather IP OK rather
i.e. it's not an IP address.
As I told you before but I'm going to define a unique rather idea for each my brothers.
And this gonna be one one one one for my rather one or other.
I define the rods variety to the second step is advertising the networks that we are directly connected
to to be our brothers and doing it using network command the first network and directly connected is
delay 1.0.
Wild Card is 0 0 0 255 because this network contains the IP addresses beginning from 11 that 1 to 2
in the two hundred and fifty four so that means that the first three bits are constant my ip addresses
will stuck with this and the last bit is arbitrary
and I'm going to define the area it says use area zero in the question and I'm using eraser.
All right.
Pretty cool.
I'm gonna use the same thing for 12 and 13.
Practical let's go to the rather two
I'm in a rather two
show IP in the race.
Brave rather too is directly connect to the twelve twenty two and twenty four networks as you can see
rather as Pier 1 again please keep in mind that process I.D. must match on for Rather's I'm going to
give the rather I'd you first and that should be this one.
No rather idea should be unique for each rather that is the idea so I'm using 2 2 2 2 for the other
2 and the last thing I need to configure is my network statements not work
zero
and are a zero OK because I'm using a sledge 2 for my network idea is twenty two that zero and because
I'm using a slash 2 and 4 again my wildcard is the 0 0 0 and 255 please keep in mind that if you're
confusing Oh my God which work her mask I need to use you can reword this too you can read rework your
subnet mask you should use 0 instead of 255 then you should use 255 instead of 0 because of on the subnet
mask is 255 255 255 0 I'm using 0 0 0 255 for my wildcard mask.
Ok I'm gonna also
advertise these networks too.
All right pretty cool but I'm expecting something to see but I couldn't I couldn't see it here.
That's what I knew.
Really need to see as you can see that as soon as I type my network statements rather to rather to has
a ways P.F. neighbor right now.
And it's rather one.
Let's see what happened.
Now I configured the SPF for this guy.
And for this guy I didn't configure SPF yet 4 rather 3 and 4 but as soon as I configure the network
statement for the link between rather one or rather two they became and was.
Ed you sent NMR all right.
Now let's take a look to the third brother enable county Varadero SPF 1 rather eighty three territory
three and I need to take a look today.
Show IP interface please.
Please keep in mind that you can use show commands even if in you are in conflict grab the remote or
config mode or config if not by using the to comment at the beginning to show IP interface brave I can
say this or I can go to the privileged exec mode and I can use the show IP interface brief and the end
result always will be the same.
Okay.
This rather has this networks and I'm going to configure them with network.
Oh well I mean network
0 0 0 255 and is 0
13 and
34.
I'm expecting to see another membership between rather one and rather three right now.
And yes as you can see that rather tree has a neighbor which is rather one and a more and now let's
go to the rather for I am rather for how enable and come to rather overspill from known network rather
idea for 4 4 4 and network statements
networks will be 44
quarter for 24 and
34 I'm expecting to neighbor ship right now for is adjacent with 2 and by 8 it was already adjacent
with the 3 or yes.
Okay 4 is adjacent with 2 and 3 right now so that and I think that we accomplished the first step step
Von okay man.
I completed you
but to where fire configuration we need to use ping from P.S. 1 2.
P.S. 4.
Let's do it
I'm in P.S. 1.
I'm going to comment prompt and typing.
Ping
four 5 which is the IP address of PCI for let's see that was going on all right I got the reply.
And that means my ISP configuration is working properly right now and I can go to the second step in
the second step.
We need to run Choi IP protocols and show ip route commands let's go to the rather one and run
show IP protocols command.
All right.
That's what I expect to see I'm running or spear with a process idea of one.
I'm just using one area I'm running for networks these guys and I have these guys in my network that's
pretty cool.
That's why show IP protocols say to us and let's take a link to the show IP Rudd command through IP
Raul All right.
As you can see there.
And as you can remember from our previous sessions connect them and local links are automatically appearing
already in my show IP right outputs but what I need to see in here also I'm learning
five different networks using the O.
Which means or its path.
I dunno this one first where it is.
I dunno this one.
I dunno this one but I learn them via the other fathers that they're using all SPF protocol to all right.
Hey man my second step is also with my accomplished okay.
Let's take a look to the last step the last step of saying as to run short PSP speed database and show
I put Dave neighbour's comments.
I'm a rather one and less strong show IP always peer database comment
show at SPF database command is showing us the topology table and we bring us the general map of our
network.
I know how to go to the destinations y edited database but the best parts are being installed to the
IP routing packed IP routing table.
Okay.
Let's take a look to the show IP or SPF neighbor zone rather run.
Well they expect to see is rather 2 and 3 which are directly connected to the rather one and the s.
As you can see that and see the seeing the rather ideas that I configured for Rather to enter a and
I'm seeing the interface and IP address information as well.
All right guys that was a really cool session and we finished it.
Thanks for viewing.
Ah or a spare lap.
