1 00:00:00,120 --> 00:00:06,050 Cwiek in our next section we're going to talk about the GOP protocol. 2 00:00:06,450 --> 00:00:09,600 Let's go ahead with the GOP overview. 3 00:00:11,170 --> 00:00:20,010 The GOP is an interview get the porticos suited for many different topologies and media in a well-designed 4 00:00:20,310 --> 00:00:21,170 network. 5 00:00:21,290 --> 00:00:30,180 Yet GOP scales well and provides extremely quick commercials time with minimal network traffic. 6 00:00:30,420 --> 00:00:39,920 Yeah GOP was proprietary until 2000 and 13 but it is industry standard now. 7 00:00:40,080 --> 00:00:49,440 Yeah GOP uses dule algorithm to find the best path and can make it cool or on cool load balancing and 8 00:00:49,710 --> 00:01:00,280 can provide summarization for each other and each interface with three types of tables that we see in 9 00:01:00,580 --> 00:01:10,390 GAAP terminology similar to OSPF and their neighbor topology and the running table neighbor table includes 10 00:01:10,480 --> 00:01:19,900 all neighbors that is directly connected to rather using Jappy topology table includes successor feasible 11 00:01:19,900 --> 00:01:28,750 successor and all other paths going to the target that work and the running table includes the best 12 00:01:28,750 --> 00:01:31,820 paths for the target network. 13 00:01:33,650 --> 00:01:37,810 We have five Pecka types in Europe and they are. 14 00:01:37,970 --> 00:01:38,830 Hello. 15 00:01:38,930 --> 00:01:43,830 Update Query reply and the EC knowledge. 16 00:01:44,030 --> 00:01:52,500 Hello Packards are used to discover the others which are using Jappy update records are sound. 17 00:01:52,520 --> 00:01:56,890 If only there is a change in our network topology. 18 00:01:56,930 --> 00:02:06,590 For example ifs if our link is down or if rather fails the query is the packet that asks if network 19 00:02:06,860 --> 00:02:10,540 cures on neighbor or not. 20 00:02:10,550 --> 00:02:20,070 Reply is the answer of course Packards and acknowledgement peccant acknowledge the query update and 21 00:02:20,100 --> 00:02:22,190 the reply packet's 22 00:02:24,840 --> 00:02:33,140 GOP uses different k values to determine the best path to each destination. 23 00:02:33,150 --> 00:02:36,870 The metric calculation is use 24 00:02:40,590 --> 00:02:42,270 by this formula. 25 00:02:42,300 --> 00:02:49,830 The metric calculation is made by using this formula actually and we have different all these as you 26 00:02:49,830 --> 00:02:58,990 can see these cables these are all numbers scale numbers in the metric curve calculation. 27 00:02:58,990 --> 00:03:11,450 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 28 00:03:11,460 --> 00:03:25,050 you by default Kavan bandwidth is equal to K3 delay and they are wan and K to load is equal to K4 reliability 29 00:03:25,060 --> 00:03:35,070 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 30 00:03:35,790 --> 00:03:39,390 metric calculation of the edge. 31 00:03:39,920 --> 00:03:42,600 This having the do logarithm. 32 00:03:42,780 --> 00:03:53,070 Yeah your P uses the fusing update algorithm to ensure that a new route is recalculated globally whenever 33 00:03:53,070 --> 00:03:56,400 it might cause a rounding loop. 34 00:03:56,400 --> 00:04:00,830 This algorithm provides Fest's cojones for yeah. 35 00:04:00,880 --> 00:04:07,550 Japie we have some terms that we are using for algorithm. 36 00:04:07,610 --> 00:04:17,380 The first term is the feasible distance feasible distance refers to Lovell's metric for the particle 37 00:04:17,380 --> 00:04:22,810 or destination and the second term is the advertised or report. 38 00:04:22,810 --> 00:04:33,440 The distance you force to the metric to a destination as advertised by a neighboring rather. 39 00:04:33,620 --> 00:04:37,280 OK let's go with another terms. 40 00:04:37,310 --> 00:04:46,460 The first term we're going to look at is the successor successor is the primary route guy's successor 41 00:04:46,460 --> 00:04:56,600 is the prime that is used for reaching 2 destination and defeasible successor is the next hope rather 42 00:04:56,600 --> 00:05:04,880 that is guaranteed not to be a part of a running loop for a particular destination and this condition 43 00:05:04,910 --> 00:05:18,810 is verified by testing administrative distance should be smaller than the feasible distance of the successor. 44 00:05:19,100 --> 00:05:25,480 All right let's take a look to do a good example for example. 45 00:05:26,140 --> 00:05:39,800 For B rather want two other three paths as you reach this network from rather one defeasible this is 46 00:05:41,210 --> 00:05:53,270 300 then one and the Edward taes this is is the distance of the neighbor and there is Tenez you can 47 00:05:53,270 --> 00:06:02,310 see it here for the path between rather 1 rather 4 which is here we can also get this network by using 48 00:06:02,310 --> 00:06:06,910 the here and four year advertised. 49 00:06:06,930 --> 00:06:12,250 This is 400 then 10 as you can see in here. 50 00:06:12,510 --> 00:06:20,280 And the answer to the feasible distance is for longer than 10 and the advertised distance this time 51 00:06:20,370 --> 00:06:36,840 is again Sam as you can see in here 300 Insan is smaller than 400 and 10 and this path are one and our 52 00:06:36,840 --> 00:06:45,660 two is the primary path for these particular destination. 53 00:06:46,020 --> 00:06:51,590 Okay let's go ahead with your periodic table and trees. 54 00:06:52,050 --> 00:06:53,030 Let's take a look. 55 00:06:53,030 --> 00:06:55,700 Sure why pure rot occiput offer. 56 00:06:55,820 --> 00:07:02,400 Are people running rather which is rather two for this scenario and we're tapping shoy route as you 57 00:07:02,400 --> 00:07:03,570 can see. 58 00:07:03,570 --> 00:07:10,750 And we have D in here as you can see which means edge. 59 00:07:11,090 --> 00:07:11,760 OK. 60 00:07:11,880 --> 00:07:14,690 It was 0 on or is there for others. 61 00:07:14,700 --> 00:07:23,060 If you're remembering this time it is D which means Japie we are running edger P and in here you're 62 00:07:23,100 --> 00:07:33,050 seeing the administrates you distance of Elijah peak which is 90 and you can see these swollen Naxa 63 00:07:33,180 --> 00:07:44,400 administrative distance and this is the feasible distance valy you and you can see the next slope in 64 00:07:44,400 --> 00:07:45,120 here. 65 00:07:45,120 --> 00:07:51,230 66 10:41 1 one which is the successor DeWyze. 67 00:07:51,250 --> 00:07:52,130 OK. 68 00:07:52,290 --> 00:07:57,400 Let's go ahead with the larger topology table entries this time. 69 00:07:57,540 --> 00:08:03,880 Here you can see on rather of three we are typing the show IP IP topology command. 70 00:08:04,320 --> 00:08:16,000 And as you can see here for example for this network 5.0 network with no one's successor with a favorable 71 00:08:16,000 --> 00:08:29,500 distance of three thousand and seventy two which means this guy says zero thirty five that five is the 72 00:08:30,050 --> 00:08:44,170 successor for the work and because of the eight minutes through distance of this that is smaller then 73 00:08:44,710 --> 00:08:49,580 the feasible distance in here the path. 74 00:08:49,650 --> 00:08:53,720 Edward why have tens zero or 34. 75 00:08:53,740 --> 00:09:01,210 That four will be the feasible successor. 76 00:09:04,760 --> 00:09:14,200 Let's go with the basic year GAAP IPV for configuration to configure any E.A.G. or Puna rather we are 77 00:09:14,200 --> 00:09:24,370 typing rather as GAAP and an X number and we're also using in year the network commands as you can see 78 00:09:24,370 --> 00:09:34,870 in Network Command enables you to GAAP on the interfaces that matched with the IP address and the wildcard 79 00:09:35,140 --> 00:09:37,030 mask as you can see. 80 00:09:37,330 --> 00:09:45,910 And each year we are also a passive interface command passive interface Gieger 0 1 that enables the 81 00:09:46,150 --> 00:09:54,580 suppression of running updates over some interfaces while it allows updates to be exchanged normally. 82 00:09:54,620 --> 00:09:56,770 Over other interface 83 00:09:59,700 --> 00:10:06,410 285 the year your peak configuration we can use the choice of porticos command. 84 00:10:07,060 --> 00:10:16,540 We can use the IP European neighbors command and church check the information about our neighbors and 85 00:10:16,570 --> 00:10:24,700 we can check the interfaces that we are using reaching our neighbor and we can see up time of the neighbor 86 00:10:24,700 --> 00:10:25,420 ship. 87 00:10:25,570 --> 00:10:34,630 And please keep in mind that we have a Maline here which is cute count that there should be zero if 88 00:10:34,630 --> 00:10:38,750 there is no problem in Jappy neighbors ship. 89 00:10:38,770 --> 00:10:42,630 Q count zero means everything is good. 90 00:10:45,370 --> 00:10:52,740 OK to where the GOP because we are also showing people what common as you know and we are eggs mind 91 00:10:52,880 --> 00:10:56,400 this out on our previous slides. 92 00:10:56,840 --> 00:11:06,560 And let's go have the basic Elijah or P IPV 6 configuration to country during the year GOP IP version 93 00:11:06,560 --> 00:11:10,770 6 rather ID is required. 94 00:11:11,000 --> 00:11:17,890 So the first thing we are going to do is typing the IP version 6 unicast to our command again. 95 00:11:18,200 --> 00:11:28,130 Then we are typing I PVC's rather Elijah P and the S number again then we are defining our rather right 96 00:11:28,130 --> 00:11:35,030 in here as you can see after we are doing the same thing with the oil spill. 97 00:11:35,050 --> 00:11:44,030 And we are getting into the interface mode and typing IPV 6 year GAAP and the S number and that is we 98 00:11:44,030 --> 00:11:53,640 are just enabling the edge Arpey under the related interface and fool for with Kishan we can use again 99 00:11:53,940 --> 00:12:05,370 short Peavey's six protocols sure why six GOP neighbors and meteor's sure IPV six route commands.
