1 00:00:00,820 --> 00:00:06,750 So what will do once again is remove the layer 3 information on switch 1 and make this into the land 2 00:00:06,780 --> 00:00:08,430 routing device. 3 00:00:08,430 --> 00:00:11,520 Once again this is not something you want to do in the real world. 4 00:00:12,330 --> 00:00:15,900 It's just to show you what's happening in the background. 5 00:00:15,900 --> 00:00:23,970 So remove the IP address from the land one from violent to and from the LAN 11 6 00:00:29,140 --> 00:00:41,800 so show IP interface brief No IP addresses or could frigate's on which one Serat of one won't be able 7 00:00:41,800 --> 00:00:44,640 to ping 10 1 to 4 right. 8 00:00:44,680 --> 00:00:49,040 One cannot ping Rato for acting as a PC. 9 00:00:49,300 --> 00:00:55,650 So let's have a look at Route Fife and configure it and run a five interface if zero slashes zero. 10 00:00:55,670 --> 00:01:01,210 No shut all that out of the interface first. 11 00:01:01,230 --> 00:01:03,720 Ethan it is 0 0 dot 1. 12 00:01:03,780 --> 00:01:06,670 This is creating a sub interface. 13 00:01:06,760 --> 00:01:13,600 If I try and configure an IP address directly on this interface it's going to fail because it needs 14 00:01:13,600 --> 00:01:15,890 to know the ADA 2.1. 15 00:01:15,940 --> 00:01:25,140 Q tagging so encapsulation top one key villain one and this is the native line. 16 00:01:25,300 --> 00:01:29,710 Now I'll be able to put an IP address on that interface subdues do show run 17 00:01:34,300 --> 00:01:39,130 no IP addresses configured on the physical interface and IP addresses configured on this subject to 18 00:01:39,130 --> 00:01:42,850 face some interface one. 19 00:01:43,030 --> 00:01:44,570 Let's create one foot two. 20 00:01:44,650 --> 00:01:48,240 So encapsulation got one key too. 21 00:01:48,340 --> 00:02:00,680 In other words we to IP Address tend to 1 to 2 to 5 4 with the mosque interface Fosset Ethernet 0 0 22 00:02:01,480 --> 00:02:11,920 11 and kept isolation not one key villaine number is 11 IP address tendered one to 11 to 4 for 23 00:02:15,550 --> 00:02:19,890 show run. 24 00:02:19,900 --> 00:02:26,200 So once again no IP address configured on the physical interface something to face one is in villaine 25 00:02:26,200 --> 00:02:27,450 one. 26 00:02:27,490 --> 00:02:32,910 It's a native land interface to these violent to it using Ed.. 27 00:02:32,930 --> 00:02:39,090 Q So having to face 11 years in Villani 11 using Ed.. 28 00:02:39,110 --> 00:02:41,810 Q These numbers don't have to match up. 29 00:02:41,830 --> 00:02:45,940 It just makes more sense to do that to keep things consistent. 30 00:02:45,940 --> 00:02:52,550 Now let's see if Rato one can ping Rotto for. 31 00:02:52,680 --> 00:02:58,520 Let's check if the traffic actually hits a Rodda 5 de-bug IP. 32 00:02:58,740 --> 00:03:02,640 I see MP Mike should can ping its default gateway 33 00:03:07,880 --> 00:03:08,970 check some obvious stuff. 34 00:03:08,970 --> 00:03:15,300 So show I've been face brief interfaces up so that's good. 35 00:03:15,380 --> 00:03:20,870 And the router thing itself so paying 10 to 1 1 2 2 4 4 36 00:03:23,940 --> 00:03:30,330 be lent to keeping itself Villani 11 can ping itself. 37 00:03:30,640 --> 00:03:37,500 Ken wrote it to ping the default gateway so who's paying for camping wrote for. 38 00:03:37,890 --> 00:03:39,700 So traffic is going from here to here. 39 00:03:39,790 --> 00:03:41,920 Let's see if we can ping its default gateway 40 00:03:46,040 --> 00:03:46,770 Camping's. 41 00:03:46,780 --> 00:03:48,650 Let's do a y shall capture. 42 00:03:48,700 --> 00:03:49,830 See what's going on. 43 00:03:56,900 --> 00:04:01,080 So no traffic arriving on this port and that's probably an issue with this hub. 44 00:04:02,960 --> 00:04:06,480 So what I'll do now is save the conflicts on the devices. 45 00:04:09,020 --> 00:04:15,440 This looks like a genius three problem and that's why sometimes you might want to use physical switches. 46 00:04:15,540 --> 00:04:24,950 So save all the configfs and then I will reboot all stop Jeana's 3 and started again. 47 00:04:26,600 --> 00:04:32,480 And then we can try again and see if it solves our problem. 48 00:04:32,540 --> 00:04:33,970 So I'm going to reboot everything. 49 00:04:34,130 --> 00:04:38,360 And in the next video we'll continue to see if it solved the problem. 50 00:04:39,710 --> 00:04:46,980 OK so after a reboot of one as an example is able to ping Rhonda too. 51 00:04:47,000 --> 00:04:50,440 So that's the device pinging this device. 52 00:04:50,520 --> 00:04:54,750 If we do a capture on that the link to run a five 53 00:04:58,100 --> 00:04:59,300 and do the ping again 54 00:05:02,210 --> 00:05:14,610 3:56 ICMP what you'll notice is the pings received from Rodda one on Villani Levan and the reply goes 55 00:05:14,610 --> 00:05:17,720 back as we learn to. 56 00:05:17,730 --> 00:05:28,440 So once again has Villani Levan and to the reply is going back as we learned to be Lenni 11 reply being 57 00:05:28,440 --> 00:05:36,000 violent to now I had some problems ingenius 3 setting this up so you may run into similar problems. 58 00:05:36,000 --> 00:05:42,840 But the moral of the story is that traffic from the species untagged here it goes across as tagged hits 59 00:05:42,840 --> 00:05:50,320 this router it does into the land routing and changes it to the and to codes is tagged here. 60 00:05:50,550 --> 00:05:55,470 Back to the switch and untagged to PC to. 61 00:05:55,650 --> 00:05:59,280 Typically once again you wouldn't want to do any of this. 62 00:05:59,460 --> 00:06:07,350 You would simply enable in TV land routing on switch one or switch to a separate video I'm going to 63 00:06:07,350 --> 00:06:14,820 show you a more realistic real world of topology and show you how to set up in TV land rotting as well 64 00:06:14,820 --> 00:06:17,880 as HAARP and spending tree optimization.
