1 00:00:00,720 --> 00:00:05,790 So can wrote up one paying wrote of five paying 10 to 1 to a tutor to 2 00:00:09,160 --> 00:00:14,410 at the moment the pings are failing so let's do a trace route to tendered one or two to two. 3 00:00:14,410 --> 00:00:21,880 So we get two tendered wondered wondered too which is rockety and then things seemed to stop working. 4 00:00:21,950 --> 00:00:29,710 Let's do a de-bug ICMP and try and ping wrote a five again 5 00:00:32,950 --> 00:00:34,710 nothing seems to be happening. 6 00:00:34,780 --> 00:00:39,780 So let's check on rodded to what the IP writing table looks like. 7 00:00:39,820 --> 00:00:43,220 We can see network Forder wandered 1.0. 8 00:00:43,270 --> 00:00:47,820 In other words the network we can see network tender wandered 3.0. 9 00:00:48,010 --> 00:00:52,480 In other words this network we can see Network 10 wondered 1.0. 10 00:00:52,510 --> 00:01:00,850 In other words this network we have a default route to router 3 but remember that rotatory doesn't have 11 00:01:00,850 --> 00:01:02,780 visibility of this network. 12 00:01:03,130 --> 00:01:07,770 If rodded to forge that traffic Gerada 3 it's going to go nowhere. 13 00:01:07,780 --> 00:01:13,810 So what we need to do is we need to run a routing protocol on Route 2 and 4 so that this network is 14 00:01:13,870 --> 00:01:20,500 advertised to Rodda to through the tunnel so that rodder to forward's traffic to run a 5 through the 15 00:01:20,500 --> 00:01:24,030 tunnel via Radio 4. 16 00:01:24,110 --> 00:01:26,370 So we should enable that some kind of writing protocol. 17 00:01:26,370 --> 00:01:29,770 I'm going to enable you to keep it simple. 18 00:01:29,900 --> 00:01:32,660 The network that I'll enable is Network 10. 19 00:01:32,690 --> 00:01:36,890 So in other words I'm not going to enable you GOP on the serial interface. 20 00:01:36,890 --> 00:01:44,180 It's going to be enabled on the fast Ethernet and tunnel interfaces only will disable Warda summarization 21 00:01:45,190 --> 00:01:51,230 to show IP your GOP interfaces shows me that your job is running on first. 22 00:01:51,230 --> 00:01:54,310 Ethan It's 0 0 and the total interface. 23 00:01:54,320 --> 00:01:58,230 It's not running on the serial interface on Radio 4. 24 00:01:58,240 --> 00:01:59,370 We can do something similar. 25 00:01:59,370 --> 00:02:04,010 Serat at your job 100 network 10.0 to start at zero. 26 00:02:04,210 --> 00:02:04,790 No. 27 00:02:04,890 --> 00:02:06,320 Or the summary. 28 00:02:06,860 --> 00:02:13,440 And notice as soon as I did that a neighbor relationship was established to neighbor 10 not one but 29 00:02:13,470 --> 00:02:19,580 three to one precinct was made after I enabled Nu-Wood a summary to that neighbor. 30 00:02:19,840 --> 00:02:26,190 So once again show IPTA GOP interfaces shows that your job is enabled on Fosset. 31 00:02:26,200 --> 00:02:35,320 Ethan It is 00 as well as the tunnel interface show IP IP neighbors. 32 00:02:35,450 --> 00:02:42,910 We can see and your GOP neighbor tendered one vote freedom one directly connected through tunnels Zira. 33 00:02:42,950 --> 00:02:45,310 The point is and forgive the pun. 34 00:02:45,380 --> 00:02:51,720 This is a point to point link so logically rodder two and four are directly connected to each other 35 00:02:52,070 --> 00:02:56,580 and yet the GOP sees them as directly connected neighbors. 36 00:02:56,580 --> 00:03:07,610 So in order to show IP route we now see a route to 10.0 one a 2.0 slash 20:4 via tunnel's zero. 37 00:03:07,620 --> 00:03:16,800 This was learnt through the GOP from neighbored tendered 1.0 to rot to now has visibility of the network 38 00:03:17,160 --> 00:03:23,840 so can Rato one ping wrote a five. 39 00:03:23,990 --> 00:03:30,480 There was a slight timeout but notice the ping now succeeds and we can see the output in the debug. 40 00:03:30,920 --> 00:03:36,680 We received an echo reply on Radio 5 just to make the point debug. 41 00:03:36,830 --> 00:03:42,770 IP ICMP ping from Rodda one once again and notice the ping succeeds. 42 00:03:42,770 --> 00:03:44,850 We can see the output. 43 00:03:45,020 --> 00:03:51,860 So we've now successfully configured a Jori tunnel from rodder to to route a full and Rato one can ping 44 00:03:52,040 --> 00:03:53,330 Rodda 5. 45 00:03:53,560 --> 00:04:03,540 But remember Rodda 3 has no visibility of the networks Rodda 3 only sees network 4. 46 00:04:03,720 --> 00:04:11,720 Todd wondered 1.0 and Ettrick forward wonder 2.0 that has no visibility of this network 10 1 1 0 or 47 00:04:11,730 --> 00:04:14,790 the US network 10 1 2 0. 48 00:04:14,820 --> 00:04:21,710 So let's look at some of the show commands available for GRB tunnels and do some additional shock captures.
