1 00:00:00,640 --> 00:00:08,010 It our next section will take a look to the EVP protocol. 2 00:00:08,250 --> 00:00:16,670 Let's go with the BJP first running protocols are basically reworded into IVP and DGP as you know as 3 00:00:16,680 --> 00:00:23,610 it can be understood from name I Gypsys are the protocols used in the Internet work for example the 4 00:00:23,610 --> 00:00:30,650 same autonomy system AJP is a jerk name for the protocols used when that works. 5 00:00:30,720 --> 00:00:40,320 In other words between the autonomy systems the is also an AGP and is very different from IGB routing 6 00:00:40,320 --> 00:00:48,400 protocols as the working Macartney's IGMP use the criteria code metric to reach a third of them work 7 00:00:48,450 --> 00:00:50,360 from one point to another. 8 00:00:50,370 --> 00:00:57,570 For example reape uses the metric hope Carvel's you know the number of layered 3D Wes's paths to reach 9 00:00:57,610 --> 00:00:59,120 the destination network. 10 00:00:59,310 --> 00:01:06,180 And OSPF and GOP first try to find the fastest line and then prefer that path. 11 00:01:06,390 --> 00:01:12,880 Unlike BGP it is a policy based world and political that allows you to control traffic flow. 12 00:01:12,910 --> 00:01:23,150 You see my musing by the many different features the main purpose of the BGP is to perform running between 13 00:01:23,390 --> 00:01:27,100 different autonomous systems without the loop. 14 00:01:29,760 --> 00:01:39,940 As you can see here we have two different phone systems and there is number 100 and the S number 200. 15 00:01:40,200 --> 00:01:48,310 There are two types of BGP and they are I BGP and the GBG pairs Yes. 16 00:01:48,640 --> 00:01:56,410 EVP is used to exchange Roths meaning routers which are in different autonomic systems as you can see 17 00:01:56,410 --> 00:02:05,410 that to provide communication that would rather see and the rather be willing to use you pay because 18 00:02:05,410 --> 00:02:08,190 rather is known as 200. 19 00:02:08,200 --> 00:02:19,150 And rather see is in as 100 and let's go ahead the configuration for the DVD Pirenne now to go figure 20 00:02:19,170 --> 00:02:29,890 the maybe GP or rather customer we are typing the rather BGP and the atheist number which are rather 21 00:02:29,890 --> 00:02:39,090 belongs to your customer rather belongs to the Sayers and our ISP rather belongs to disaster and we're 22 00:02:39,140 --> 00:02:48,610 turning on the ISP side rather BGP and the x number of each ISP rather belongs to them. 23 00:02:48,610 --> 00:02:57,100 What are we going to do in here is defining the neighbors many the Indeed we are defining our neighbors. 24 00:02:57,100 --> 00:03:04,690 Many of the guys please pay attention to this from on customer rather than going to define who is defining 25 00:03:04,690 --> 00:03:10,830 the IP address of the ISP rather as my neighbor so I'm typing neighbor. 26 00:03:11,200 --> 00:03:25,030 The IP address of the ISP rather and the remote the S of S number which is the s that ISP rather belongs 27 00:03:25,270 --> 00:03:26,920 to. 28 00:03:27,160 --> 00:03:32,210 The same thing on the ISP rather too as you can see here. 29 00:03:32,380 --> 00:03:41,230 And this time I'm defining this IP address as my neighbor and they say it's number as removed as an 30 00:03:41,880 --> 00:03:44,500 arm and not Simyra. 31 00:03:44,530 --> 00:03:54,270 By typing the statements in here for example for customer rather I I'm trying to announce this network 32 00:03:54,900 --> 00:04:05,350 which is connected gigs 0 1 and I'm using the mask T-word me for my subnet mask and two were fighting 33 00:04:05,420 --> 00:04:14,920 it is the configuration I knew the show I paid BGP summary command and I can't see my neighbors details. 34 00:04:14,920 --> 00:04:17,470 As you can see here it is again seen here. 35 00:04:17,500 --> 00:04:22,350 I have a neighbor for the customer other is to anyone that too. 36 00:04:22,540 --> 00:04:31,540 OK this is that the IP address of the ISP rather than the ISP rather is belonging to these. 37 00:04:31,900 --> 00:04:40,840 Which is correct and I can see the the old timers and the prefix and the states through suit and some 38 00:04:40,840 --> 00:04:49,770 information like that and I can also use the short piu rocks common to all our customers other to see 39 00:04:49,770 --> 00:04:51,110 the BGP route. 40 00:04:51,130 --> 00:05:02,050 For example being forced to BGP here and I can check if I'm receiving some much from the ISP rather 41 00:05:02,140 --> 00:05:12,460 or not and the third movie Kaisha made of is the show IP BGP command Bursch by using the show my PBT 42 00:05:12,630 --> 00:05:13,360 command. 43 00:05:13,470 --> 00:05:22,450 I can see the networks that I'm receiving from the ISP or other and I can see the next hope that I'm 44 00:05:22,450 --> 00:05:24,060 missing the one. 45 00:05:24,270 --> 00:05:26,160 And I can also use the. 46 00:05:26,220 --> 00:05:34,730 I can also check the metric local preference weight and the remove the AST number as well.
