All language subtitles for 17. EIGRP Overview & Basic Configuration

Cwiek in our next section we're going to talk about the GOP protocol.

Let's go ahead with the GOP overview.

The GOP is an interview get the porticos suited for many different topologies and media in a well-designed

network.

Yet GOP scales well and provides extremely quick commercials time with minimal network traffic.

Yeah GOP was proprietary until 2000 and 13 but it is industry standard now.

Yeah GOP uses dule algorithm to find the best path and can make it cool or on cool load balancing and

can provide summarization for each other and each interface with three types of tables that we see in

GAAP terminology similar to OSPF and their neighbor topology and the running table neighbor table includes

all neighbors that is directly connected to rather using Jappy topology table includes successor feasible

successor and all other paths going to the target that work and the running table includes the best

paths for the target network.

We have five Pecka types in Europe and they are.

Hello.

Update Query reply and the EC knowledge.

Hello Packards are used to discover the others which are using Jappy update records are sound.

If only there is a change in our network topology.

For example ifs if our link is down or if rather fails the query is the packet that asks if network

cures on neighbor or not.

Reply is the answer of course Packards and acknowledgement peccant acknowledge the query update and

the reply packet's

GOP uses different k values to determine the best path to each destination.

The metric calculation is use

by this formula.

The metric calculation is made by using this formula actually and we have different all these as you

can see these cables these are all numbers scale numbers in the metric curve calculation.

K One is the bandwidth K-2 is the load K-3 is the delay K-4 is the reliability and K 5 is the anti-balaka

you by default Kavan bandwidth is equal to K3 delay and they are wan and K to load is equal to K4 reliability

and that is equal to K 5 and 2 and there are as soon as 0 and end result here is the formula of the

metric calculation of the edge.

This having the do logarithm.

Yeah your P uses the fusing update algorithm to ensure that a new route is recalculated globally whenever

it might cause a rounding loop.

This algorithm provides Fest's cojones for yeah.

Japie we have some terms that we are using for algorithm.

The first term is the feasible distance feasible distance refers to Lovell's metric for the particle

or destination and the second term is the advertised or report.

The distance you force to the metric to a destination as advertised by a neighboring rather.

OK let's go with another terms.

The first term we're going to look at is the successor successor is the primary route guy's successor

is the prime that is used for reaching 2 destination and defeasible successor is the next hope rather

that is guaranteed not to be a part of a running loop for a particular destination and this condition

is verified by testing administrative distance should be smaller than the feasible distance of the successor.

All right let's take a look to do a good example for example.

For B rather want two other three paths as you reach this network from rather one defeasible this is

300 then one and the Edward taes this is is the distance of the neighbor and there is Tenez you can

see it here for the path between rather 1 rather 4 which is here we can also get this network by using

the here and four year advertised.

This is 400 then 10 as you can see in here.

And the answer to the feasible distance is for longer than 10 and the advertised distance this time

is again Sam as you can see in here 300 Insan is smaller than 400 and 10 and this path are one and our

two is the primary path for these particular destination.

Okay let's go ahead with your periodic table and trees.

Let's take a look.

Sure why pure rot occiput offer.

Are people running rather which is rather two for this scenario and we're tapping shoy route as you

can see.

And we have D in here as you can see which means edge.

OK.

It was 0 on or is there for others.

If you're remembering this time it is D which means Japie we are running edger P and in here you're

seeing the administrates you distance of Elijah peak which is 90 and you can see these swollen Naxa

administrative distance and this is the feasible distance valy you and you can see the next slope in

here.

OK.

Let's go ahead with the larger topology table entries this time.

Here you can see on rather of three we are typing the show IP IP topology command.

And as you can see here for example for this network 5.0 network with no one's successor with a favorable

distance of three thousand and seventy two which means this guy says zero thirty five that five is the

successor for the work and because of the eight minutes through distance of this that is smaller then

the feasible distance in here the path.

Edward why have tens zero or 34.

That four will be the feasible successor.

Let's go with the basic year GAAP IPV for configuration to configure any E.A.G. or Puna rather we are

typing rather as GAAP and an X number and we're also using in year the network commands as you can see

in Network Command enables you to GAAP on the interfaces that matched with the IP address and the wildcard

mask as you can see.

And each year we are also a passive interface command passive interface Gieger 0 1 that enables the

suppression of running updates over some interfaces while it allows updates to be exchanged normally.

Over other interface

285 the year your peak configuration we can use the choice of porticos command.

We can use the IP European neighbors command and church check the information about our neighbors and

we can check the interfaces that we are using reaching our neighbor and we can see up time of the neighbor

ship.

And please keep in mind that we have a Maline here which is cute count that there should be zero if

there is no problem in Jappy neighbors ship.

Q count zero means everything is good.

OK to where the GOP because we are also showing people what common as you know and we are eggs mind

this out on our previous slides.

And let's go have the basic Elijah or P IPV 6 configuration to country during the year GOP IP version

6 rather ID is required.

So the first thing we are going to do is typing the IP version 6 unicast to our command again.

Then we are typing I PVC's rather Elijah P and the S number again then we are defining our rather right

in here as you can see after we are doing the same thing with the oil spill.

And we are getting into the interface mode and typing IPV 6 year GAAP and the S number and that is we

are just enabling the edge Arpey under the related interface and fool for with Kishan we can use again

short Peavey's six protocols sure why six GOP neighbors and meteor's sure IPV six route commands.
