1 00:00:00,400 --> 00:00:06,890 It in a sexual way and take it to the point to point let's go ahead with that point of point. 2 00:00:06,890 --> 00:00:14,810 Poor call Point to Point porticos people he is a datalink clear communications protocols used to establish 3 00:00:14,870 --> 00:00:18,610 a direct connection between two notes. 4 00:00:18,620 --> 00:00:25,130 It connects to others directly without any host or any other networking device in between it's camp 5 00:00:25,130 --> 00:00:32,330 provides a connection authentication transmission encryption and cooperation optional optionally this 6 00:00:32,330 --> 00:00:39,700 particle is used over many types of physical networks including the serial cable phone line cellular 7 00:00:39,700 --> 00:00:42,920 telephone fiber optic links and etc.. 8 00:00:43,160 --> 00:00:48,370 PKP also supports authentication by PAP and Chapur recalls. 9 00:00:48,380 --> 00:00:55,190 And additionally can monitored the quality of the link by link quality management feature and takes 10 00:00:55,190 --> 00:00:55,870 the link down. 11 00:00:55,880 --> 00:01:10,660 If there is too much errors the main PBB components are see LCP and the NCP HDL C is used for encapsulating 12 00:01:10,750 --> 00:01:19,050 that grounds LCP refers to the control protocol and is used for setting up maintaining terminating the 13 00:01:19,050 --> 00:01:24,130 link between the Wes's and handling were writing limits on packet size. 14 00:01:24,160 --> 00:01:31,600 NCP refers to network control porticoes and is used for establishing and configuring different network 15 00:01:31,600 --> 00:01:37,960 clear protocols such as IPV for IP V-6 IPX and Etzler. 16 00:01:38,430 --> 00:01:42,180 Let's go ahead with the p p p frame in the PPV frame. 17 00:01:42,180 --> 00:01:50,760 Again we have some different fields and one byte of the Lakefield and one byte with the Edwards field. 18 00:01:50,820 --> 00:01:54,480 We have combed through all fields which consists of one byte. 19 00:01:54,480 --> 00:01:59,670 Again we poor local field that there may be one or two bytes. 20 00:01:59,810 --> 00:02:10,010 We are payload which is where I bowl and we have FCC Frenchy's sequences and the flag fills in our free 21 00:02:12,250 --> 00:02:21,490 to establish epeople P.S. We have some phrases and in the phrase one link establishment and configuration 22 00:02:21,490 --> 00:02:25,120 negotiation is met in this phase. 23 00:02:25,150 --> 00:02:34,090 LCP opens the connection and negotiates the configuration options and this phase finishes when the receiving 24 00:02:34,090 --> 00:02:42,390 rather Senza configuration acknowledgment for him back to the rudder initiating the connection interface 25 00:02:42,430 --> 00:02:51,300 to cool the off link is checked which is an optional step and in the step LCP test linked to that mine. 26 00:02:51,440 --> 00:02:59,770 Whether the link called it is sufficient to bring up network layer protocols and in the last phrase 27 00:02:59,800 --> 00:03:07,540 which is phrased to in here network where political configuration negotiation is made and after the 28 00:03:07,540 --> 00:03:16,000 LCP has finished doing quoted the termination phrase the appropriate NCP can separately configured the 29 00:03:15,990 --> 00:03:22,980 network protocols and brings them up and take them down at any time. 30 00:03:23,000 --> 00:03:30,240 Let's go ahead of the configuration of the point to point protocol to configure the point to point protocol 31 00:03:30,270 --> 00:03:38,780 we have some options that we can use and there are authentication compression error detection people 32 00:03:38,790 --> 00:03:41,660 be called back and the multa link. 33 00:03:41,700 --> 00:03:44,370 And let's take a look to these guys now. 34 00:03:45,730 --> 00:03:53,800 Authentication can be made by the PAP and the CHEP protocols for people be correct. 35 00:03:54,040 --> 00:04:00,370 Let's go ahead with Pepp authentication first which transmits on an encrypted Eski passwords over the 36 00:04:00,370 --> 00:04:09,100 network in here if you want support authentication would mean rather X and rather Y rather X sends its 37 00:04:09,190 --> 00:04:18,100 own parameters which is user rather X password strong pass or something like that rather x' permit those 38 00:04:18,100 --> 00:04:21,760 are checked on rather Weist local database. 39 00:04:21,910 --> 00:04:30,910 And if the parameters are matched communication is as stablished and rather white will accept or reject 40 00:04:30,910 --> 00:04:31,840 message too. 41 00:04:31,910 --> 00:04:40,780 Rather why let's go ahead with the Chapeltown get in the year Firstly rather why this time sends a challenge 42 00:04:40,780 --> 00:04:49,840 message and starts with the three way handshake this time rather X response with its own username and 43 00:04:49,840 --> 00:04:52,960 the passport again as you can see in here. 44 00:04:53,110 --> 00:05:01,690 Then run why compares the permit others on it's own local and accept or reject the communication as 45 00:05:01,690 --> 00:05:03,860 you can see. 46 00:05:03,880 --> 00:05:07,150 Let's go with the cooperation cooperation. 47 00:05:07,200 --> 00:05:15,040 It increases the effective throughput on people the connections by reducing the amount of data in Frane 48 00:05:15,430 --> 00:05:23,730 we can use this record or the predictor protocols for cooperation on point to point protocol. 49 00:05:24,840 --> 00:05:29,060 Error the direction identifies fault conditions. 50 00:05:29,280 --> 00:05:33,060 There are two options the call the and the magic number. 51 00:05:33,150 --> 00:05:37,920 Help ensure reliable loop free data link. 52 00:05:38,010 --> 00:05:45,420 The magic number field helps in detecting links that are in a loop spec condition and are generated 53 00:05:45,420 --> 00:05:49,290 randomly at each end of the connection. 54 00:05:49,290 --> 00:05:51,470 Let's go ahead with the code. 55 00:05:51,480 --> 00:05:59,280 Back security people came before to augment that with the use of people be called back people they called 56 00:05:59,290 --> 00:06:04,680 back is through X the access server to disconnect the incoming connection. 57 00:06:04,680 --> 00:06:14,460 After a successful authentication and reestablish the connection wire and outbound call and the last 58 00:06:14,460 --> 00:06:21,810 feature we are going to focus on is the multa link monitoring is used to take multiple people buildings 59 00:06:21,870 --> 00:06:28,890 and bomb them together making them act as a single people building and pro-ISIS load balancing as you 60 00:06:28,890 --> 00:06:38,880 can see in here we have two separate warnings in here and one mottling is doing actually is this is 61 00:06:38,880 --> 00:06:47,590 combining the two separate wings together and bonding them together as a single link. 62 00:06:47,590 --> 00:06:48,220 Let's go ahead. 63 00:06:48,220 --> 00:06:55,390 The point of point particle configuration and troubleshooting Let's go ahead with the how we can call 64 00:06:55,390 --> 00:07:05,050 for you to be forced to cover your pee pee pee guys all are rather what I'm going to do is just going 65 00:07:05,170 --> 00:07:12,610 under the interface more for us by typing the interface and the interface name. 66 00:07:12,610 --> 00:07:23,100 Basically then we're defining an encapsulation method and our encapsulation method will be p p p point 67 00:07:23,100 --> 00:07:30,690 to point particle then optionally we can define a compressed method or we can define the people pick 68 00:07:30,870 --> 00:07:37,360 Lenku multi-byte slapping the corporis predictor and Peepy Piccoli 80 69 00:07:39,960 --> 00:07:47,020 let's go ahead how we can Cuvier people Piramal killing as you can see that we have two separate things. 70 00:07:47,160 --> 00:07:54,930 And what we are doing here is just to combine them together for load balancing purposes to configure 71 00:07:54,930 --> 00:08:02,890 the people appear on our rather Again we're just getting into the interface more buzz by typing this 72 00:08:02,900 --> 00:08:12,420 on interface Malto link and the monthly number then we are defining our IP address. 73 00:08:12,540 --> 00:08:21,300 And the thing we are going to do this time is typing the BPP multilane and people multiplying group 74 00:08:21,330 --> 00:08:31,860 and the group number them we are getting into the serial interfaces by typing the serial 0 3 0 and serial 75 00:08:31,860 --> 00:08:33,290 3 0 1. 76 00:08:33,540 --> 00:08:37,190 There we are defining our encapsulation as. 77 00:08:37,620 --> 00:08:47,550 And we are no IP address TPP multilane and the PBT mottling group one for the both of our interfaces. 78 00:08:47,580 --> 00:08:55,170 This configuration should be made on rather too as well as you can see to refer to PBB configuration. 79 00:08:55,210 --> 00:09:04,850 We can turn the show interface and the interface name command and we can check the encapsulation meated 80 00:09:04,930 --> 00:09:10,020 and we can check if LCP is open or not. 81 00:09:11,380 --> 00:09:16,060 Let's go and how we can configure the authentication for druthers. 82 00:09:16,060 --> 00:09:22,010 The first thing we're going to focus on is configuring the pap to configure the PAP. 83 00:09:22,030 --> 00:09:29,330 What we are doing or rather X is to define the rather wise parameters. 84 00:09:29,800 --> 00:09:36,970 But surely there's something wrong in the figure the Celene step is not available for the purposes you 85 00:09:36,970 --> 00:09:37,800 know. 86 00:09:37,990 --> 00:09:39,950 So I'm cleaning this out. 87 00:09:39,970 --> 00:09:42,210 Sorry guys there's not challenge step 88 00:09:44,950 --> 00:09:45,890 OK. 89 00:09:46,760 --> 00:09:54,200 No response to just this guy will send the message and this guy the other guy will tell me they accept 90 00:09:54,200 --> 00:09:55,120 or reject. 91 00:09:55,130 --> 00:10:02,320 So what are we going to do on the rather Aksa is to define the rather wise leaders own rather Rake's 92 00:10:02,330 --> 00:10:05,930 we are attacking the user name rather why. 93 00:10:06,260 --> 00:10:15,120 And the passport as soon pass and and in the interface most people rather as we are defining the people 94 00:10:15,500 --> 00:10:26,390 or complication as Pap and we're also defining the own username and password of two other eggs by typing 95 00:10:26,390 --> 00:10:36,930 the p p p pap Sentier is her name rather X and passport with strong past this line in here means I'm 96 00:10:36,930 --> 00:10:45,970 going to send there rather X as user name but rather an answer I'm going to send a rather why as do 97 00:10:46,030 --> 00:10:51,220 other X as my username and the passport strong pass. 98 00:10:51,440 --> 00:10:58,310 So what I'm going to come for you or rather what this time is firstly is the parameters of the rather 99 00:10:58,730 --> 00:11:06,920 X-ers you can see in here inserting the username Roderick's password and the strong pass again then 100 00:11:06,980 --> 00:11:15,140 under the interface mode and defining the authentication protocol as pep then what then defining in 101 00:11:15,170 --> 00:11:27,260 here is the DPP Pepp sent username and rather why as the rather wise on username and password will be 102 00:11:27,500 --> 00:11:29,380 strong press again. 103 00:11:30,230 --> 00:11:37,510 And let's go back to covering the CHEP challenge handshake authentication protocol this term again and 104 00:11:37,520 --> 00:11:44,060 defining the rather words per meters or rather X and rather X as per meters on rather why and the difference 105 00:11:44,060 --> 00:11:54,350 is Peepy authentication Pugel will be just CHEP in here is as you can see this we have just two steps 106 00:11:54,380 --> 00:12:01,100 and we are defining our user names of the remote networks Lehman Brothers and we are defining the authentication 107 00:12:01,100 --> 00:12:11,600 protocol as CHEP to troubleshoot the PBT connection we are typing the debark BPP authentication which 108 00:12:11,600 --> 00:12:14,570 displays authentication Xchange sequence. 109 00:12:14,750 --> 00:12:22,400 We can't write the book peepin negotiation which displays packets during connection establishment. 110 00:12:22,400 --> 00:12:30,110 We didn't write the DBA BPP packets which displays the BBB packets being sent and received. 111 00:12:30,110 --> 00:12:37,310 We can tap the Dilbert BPP URL which displays poor local errors and the error statistics and we can 112 00:12:37,310 --> 00:12:42,830 use the debug PBB chip command to display the CHEP packet extranets.
