Now in a previous video we configured HAARP between switch one and switch to previous to that video
we configure trunk links access ports and spending tree and we enhance the convergence timer's of these
devices to improve the way that the network handles failures and the utilization of uplinks in this
video we going to enable the GOP on switch one and switch to as well as on router three.
Now let's say just our Pirata doesn't actually exist.
It's only shown in the typology to show you that HAARP is configured between switch one and switch 2.
So don't let it confuse you.
The router is actually turned off it's only here as an icon.
It's not actually connected to any devices in the topology at all.
So we get enable the GOP on switch one switch to and Rodders three and then advertise a default route
from router 3 to these two switches in a subsequent video Ali cable network address translation on router
3 so that these devices especially the Router one or two devices acting as PCs can access the Internet.
So let's get started.
On switch one type enable confetti router and I can select various routing protocols.
I'm going to select the GOP I need to specify and antonymous system number.
If the system number is not the same the broadcast won't automatically exchange rates with each other.
So before I go any further do show IP protocols.
I can see that your GOP is being configured but we're not advertising any networks at the moment.
I need to advertise networks using the network command.
So as an example I could simply enter network 10.0 0.0 and that will enable your job on all interfaces
in the 10 network.
So do show IP protocols now shows me that your job is writing for networks 10.
The idea is this and your job P is enabled on these interfaces so do show IPR jobby interfaces shows
me that your job is enabled on villaine one violent 10 and villaine 20.
If I removed the network command and did that command again so do show IP job interfaces I would see
that your job is not enabled on any interfaces which means no networks will be advertised and your job
will not form relationships with any devices on any interfaces so Network 10 again.
Yeah.
Now we enabled on villaine one 10 and 20 and to make it easy I'll just get back to privilege mode.
So show IP your job.
We've already seen the interfaces and there are other options available include neighbors at the moment
there are no E-I GOP neighbors because I haven't enabled you GOP and any other devices.
I can look at the typologies so show IPTA GOP typology the routes that are going to be advertised in
your job include tendered wonder 10.0 I-Slash 24 tendered wonder 10 to 20 Flesch 24 as well as tendered
one to one hundred its era slushed 24 show run pipe section on GOP this is the GOP configuration that
we've done now as a rule of thumb you're going to want to use the note or just summary command to disable
automatic summarization in the video I showed you a problem with automatic summarization and the same
will happen with the job.
It's good practice to disable automatic summarization in your job.
So show run pipe section your job he all we've done is use the network command and disable automatic
summarization.
Now on this device automatic summarization in your job is disabled by default so notice automatic summarization
disabled.
Now let's prove that by doing a similar configuration on switch to serrata your job 100 network 10.0
added 0 0 to show IP protocol.
Just before I Precentor notice neighbor relationships have been formed between switch to and switch
one on villaine one the last 10 and Vilain 20 but do show IP protocols shows me that all the Medek summarization
is disabled.
This will be dependent on the version of Ioway sketchy using switch to is routing for network 10 and
is getting information from switch one on VLAN 10 and 20 and we land one back on switch one previously
we were routing full network 10 but we didn't have any writing information sources.
Now however we've got neighbor relationships on VLAN one villain 10 and Villon 20 show IP protocols
shows me that we've got these sources of routing information show IP Japie neighbors
so show Piaggio the neighbors shows us that we have three neighboring relationships.
So a neighbor relationship is established on every LAN show IP route at the moment.
We don't see any GOP rats in the running table so there are no deep entries because both these writers
are connected physically to all networks in this typology that lets enable you know GOP on Radio 3 and
they will advertise a rat into the typology.
