It in a sexual way and take it to the point to point let's go ahead with that point of point.
Poor call Point to Point porticos people he is a datalink clear communications protocols used to establish
a direct connection between two notes.
It connects to others directly without any host or any other networking device in between it's camp
provides a connection authentication transmission encryption and cooperation optional optionally this
particle is used over many types of physical networks including the serial cable phone line cellular
telephone fiber optic links and etc..
PKP also supports authentication by PAP and Chapur recalls.
And additionally can monitored the quality of the link by link quality management feature and takes
the link down.
If there is too much errors the main PBB components are see LCP and the NCP HDL C is used for encapsulating
that grounds LCP refers to the control protocol and is used for setting up maintaining terminating the
link between the Wes's and handling were writing limits on packet size.
NCP refers to network control porticoes and is used for establishing and configuring different network
clear protocols such as IPV for IP V-6 IPX and Etzler.
Let's go ahead with the p p p frame in the PPV frame.
Again we have some different fields and one byte of the Lakefield and one byte with the Edwards field.
We have combed through all fields which consists of one byte.
Again we poor local field that there may be one or two bytes.
We are payload which is where I bowl and we have FCC Frenchy's sequences and the flag fills in our free
to establish epeople P.S. We have some phrases and in the phrase one link establishment and configuration
negotiation is met in this phase.
LCP opens the connection and negotiates the configuration options and this phase finishes when the receiving
rather Senza configuration acknowledgment for him back to the rudder initiating the connection interface
to cool the off link is checked which is an optional step and in the step LCP test linked to that mine.
Whether the link called it is sufficient to bring up network layer protocols and in the last phrase
which is phrased to in here network where political configuration negotiation is made and after the
LCP has finished doing quoted the termination phrase the appropriate NCP can separately configured the
network protocols and brings them up and take them down at any time.
Let's go ahead of the configuration of the point to point protocol to configure the point to point protocol
we have some options that we can use and there are authentication compression error detection people
be called back and the multa link.
And let's take a look to these guys now.
Authentication can be made by the PAP and the CHEP protocols for people be correct.
Let's go ahead with Pepp authentication first which transmits on an encrypted Eski passwords over the
network in here if you want support authentication would mean rather X and rather Y rather X sends its
own parameters which is user rather X password strong pass or something like that rather x' permit those
are checked on rather Weist local database.
And if the parameters are matched communication is as stablished and rather white will accept or reject
message too.
Rather why let's go ahead with the Chapeltown get in the year Firstly rather why this time sends a challenge
message and starts with the three way handshake this time rather X response with its own username and
the passport again as you can see in here.
Then run why compares the permit others on it's own local and accept or reject the communication as
you can see.
Let's go with the cooperation cooperation.
It increases the effective throughput on people the connections by reducing the amount of data in Frane
we can use this record or the predictor protocols for cooperation on point to point protocol.
Error the direction identifies fault conditions.
There are two options the call the and the magic number.
Help ensure reliable loop free data link.
The magic number field helps in detecting links that are in a loop spec condition and are generated
randomly at each end of the connection.
Let's go ahead with the code.
Back security people came before to augment that with the use of people be called back people they called
back is through X the access server to disconnect the incoming connection.
After a successful authentication and reestablish the connection wire and outbound call and the last
feature we are going to focus on is the multa link monitoring is used to take multiple people buildings
and bomb them together making them act as a single people building and pro-ISIS load balancing as you
can see in here we have two separate warnings in here and one mottling is doing actually is this is
combining the two separate wings together and bonding them together as a single link.
Let's go ahead.
The point of point particle configuration and troubleshooting Let's go ahead with the how we can call
for you to be forced to cover your pee pee pee guys all are rather what I'm going to do is just going
under the interface more for us by typing the interface and the interface name.
Basically then we're defining an encapsulation method and our encapsulation method will be p p p point
to point particle then optionally we can define a compressed method or we can define the people pick
Lenku multi-byte slapping the corporis predictor and Peepy Piccoli 80
let's go ahead how we can Cuvier people Piramal killing as you can see that we have two separate things.
And what we are doing here is just to combine them together for load balancing purposes to configure
the people appear on our rather Again we're just getting into the interface more buzz by typing this
on interface Malto link and the monthly number then we are defining our IP address.
And the thing we are going to do this time is typing the BPP multilane and people multiplying group
and the group number them we are getting into the serial interfaces by typing the serial 0 3 0 and serial
3 0 1.
There we are defining our encapsulation as.
And we are no IP address TPP multilane and the PBT mottling group one for the both of our interfaces.
This configuration should be made on rather too as well as you can see to refer to PBB configuration.
We can turn the show interface and the interface name command and we can check the encapsulation meated
and we can check if LCP is open or not.
Let's go and how we can configure the authentication for druthers.
The first thing we're going to focus on is configuring the pap to configure the PAP.
What we are doing or rather X is to define the rather wise parameters.
But surely there's something wrong in the figure the Celene step is not available for the purposes you
know.
So I'm cleaning this out.
Sorry guys there's not challenge step
OK.
No response to just this guy will send the message and this guy the other guy will tell me they accept
or reject.
So what are we going to do on the rather Aksa is to define the rather wise leaders own rather Rake's
we are attacking the user name rather why.
And the passport as soon pass and and in the interface most people rather as we are defining the people
or complication as Pap and we're also defining the own username and password of two other eggs by typing
the p p p pap Sentier is her name rather X and passport with strong past this line in here means I'm
going to send there rather X as user name but rather an answer I'm going to send a rather why as do
other X as my username and the passport strong pass.
So what I'm going to come for you or rather what this time is firstly is the parameters of the rather
X-ers you can see in here inserting the username Roderick's password and the strong pass again then
under the interface mode and defining the authentication protocol as pep then what then defining in
here is the DPP Pepp sent username and rather why as the rather wise on username and password will be
strong press again.
And let's go back to covering the CHEP challenge handshake authentication protocol this term again and
defining the rather words per meters or rather X and rather X as per meters on rather why and the difference
is Peepy authentication Pugel will be just CHEP in here is as you can see this we have just two steps
and we are defining our user names of the remote networks Lehman Brothers and we are defining the authentication
protocol as CHEP to troubleshoot the PBT connection we are typing the debark BPP authentication which
displays authentication Xchange sequence.
We can't write the book peepin negotiation which displays packets during connection establishment.
We didn't write the DBA BPP packets which displays the BBB packets being sent and received.
We can tap the Dilbert BPP URL which displays poor local errors and the error statistics and we can
use the debug PBB chip command to display the CHEP packet extranets.
