WEBVTT 1 00:00.000 --> 00:09.000 Finally, let's take a look at using DIA links at a co-location. 2 00:09.000 --> 00:13.960 Now this is going to be very, very similar to using a gateway site. 3 00:13.960 --> 00:15.960 So this is going to be a very quick discussion. 4 00:15.960 --> 00:18.760 We just want to talk about some of the subtle differences. 5 00:18.760 --> 00:22.890 Other than that, the forwarding is going to be handled pretty much the same way 6 00:22.890 --> 00:23.000 . 7 00:23.000 --> 00:28.720 Let's go ahead and take a look at some of those minor changes. 8 00:28.720 --> 00:35.320 So the basic idea behind this design is we're going to now use a regional hub WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 8 00:28.720 --> 00:35.320 So the basic idea behind this design is we're going to now use a regional hub 9 00:35.320 --> 00:36.440 that has direct 10 00:36.440 --> 00:38.320 internet access. 11 00:38.320 --> 00:43.360 The branch sites then connect to that regional hub for their internet 12 00:43.360 --> 00:44.560 connection. 13 00:44.560 --> 00:49.560 So in this example, the branch sites don't have their own internet connection. 14 00:49.560 --> 00:52.960 Although truth be told, they really still could. 15 00:52.960 --> 00:56.400 That's just not really part of this particular design. 16 00:56.400 --> 01:00.960 And sort of the way it gets its name is oftentimes companies are going to WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 16 00:56.400 --> 01:00.960 And sort of the way it gets its name is oftentimes companies are going to 17 01:00.960 --> 01:02.640 choose to host these 18 01:02.640 --> 01:11.640 hubs at either a co-location or a CNF, which is a carrier neutral facility. 19 01:11.640 --> 01:16.630 Usually places that carry multiple different providers that we can use for that 20 01:16.630 --> 01:17.280 internet 21 01:17.280 --> 01:18.720 access. 22 01:18.720 --> 01:25.380 So then this is as simple as deploying SD-WAN edge routers at these regional 23 01:25.380 --> 01:26.560 offices. 24 01:26.560 --> 01:30.420 And those are then configured as gateway sites. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 24 01:26.560 --> 01:30.420 And those are then configured as gateway sites. 25 01:30.420 --> 01:34.610 So you can sort of see here how this isn't really all that different from the 26 01:34.610 --> 01:35.400 other gateway 27 01:35.400 --> 01:36.400 sites. 28 01:36.400 --> 01:41.320 It's just being hosted at a co-location or a CNF. 29 01:41.320 --> 01:45.960 Sort of the fundamental difference is that connection to the gateway site is 30 01:45.960 --> 01:46.440 going to 31 01:46.440 --> 01:48.680 be over a private connection. 32 01:48.680 --> 01:53.300 Again, the assumption is that the branch office doesn't have its own internet 33 01:53.300 --> 01:54.240 connection. 34 01:54.240 --> 01:56.560 It's a private WAN connection. 35 01:56.560 --> 02:01.180 Now just like always, we're still going to choose the best path and we're going WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 35 01:56.560 --> 02:01.180 Now just like always, we're still going to choose the best path and we're going 36 02:01.180 --> 02:02.040 to choose 37 02:02.040 --> 02:06.120 the best path the same way as we did before. 38 02:06.120 --> 02:11.650 So this follows that same forwarding logic that we did in the previous video 39 02:11.650 --> 02:12.400 where we 40 02:12.400 --> 02:15.800 talked about using a gateway site. 41 02:15.800 --> 02:18.400 So again, almost an identical model. 42 02:18.400 --> 02:23.240 The only difference here is we're hosting it at a co-location and we have our 43 02:23.240 --> 02:24.080 own SD-WAN 44 02:24.080 --> 02:30.800 edge routers at that co-location that's then acting as our gateway site. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 44 02:24.080 --> 02:30.800 edge routers at that co-location that's then acting as our gateway site. 45 02:30.800 --> 02:35.540 In this video, we talked about some of the minor changes that happened with our 46 02:35.540 --> 02:36.000 model 47 02:36.000 --> 02:43.480 where we decided to use a co-location or a CNF to host our own SD-WAN routers 48 02:43.480 --> 02:44.040 that then 49 02:44.040 --> 02:46.360 act as a gateway site. 50 02:46.360 --> 02:51.430 Again, the logic with the forwarding here is the same as it is with any other 51 02:51.430 --> 02:51.800 gateway 52 02:51.800 --> 02:53.120 site. 53 02:53.120 --> 02:57.860 So that actually concludes everything we need to discuss in this skill, which 54 02:57.860 --> 02:58.880 leaves us 55 02:58.880 --> 03:00.840 with just the challenge. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 55 02:58.880 --> 03:00.840 with just the challenge. 56 03:00.840 --> 03:05.650 So go ahead and tackle that challenge and I'll see you in the solution video on 57 03:05.650 --> 03:06.160 the other 58 03:06.160 --> 03:06.640 side.
