WEBVTT 1 00:00.000 --> 00:03.720 Hello and welcome. My name is Keith Barker. 2 00:03.720 --> 00:06.280 And sometimes it makes sense to separate things. 3 00:06.280 --> 00:09.360 An example might be something like you have a couple of kids that are fighting. 4 00:09.360 --> 00:12.080 You know, at that moment, it might be good to go ahead and separate them 5 00:12.080 --> 00:13.120 and keep them separate. 6 00:13.120 --> 00:16.080 Or if you have like two different people from two different families, 7 00:16.080 --> 00:17.040 they have their own stuff. 8 00:17.040 --> 00:19.440 You might want to have separate storage for each of them. 9 00:19.440 --> 00:21.440 You know, this person keeps all their stuff here 10 00:21.440 --> 00:23.920 and the other person keeps all their stuff over there. 11 00:23.920 --> 00:27.570 So you might ask, well, what does this got to do with NSX and networking within 12 00:27.570 --> 00:28.800 the world of NSX? 13 00:28.800 --> 00:31.840 And the answer is we may have more than just one customer. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 13 00:28.800 --> 00:31.840 And the answer is we may have more than just one customer. 14 00:31.840 --> 00:33.200 For example, it may not just be us. 15 00:33.200 --> 00:37.760 Maybe we're hosting services for multiple customers, also known as tenants. 16 00:37.760 --> 00:41.760 So if we have customer one here and customer two here and customer three here, 17 00:41.760 --> 00:44.480 they all may want to choose networks that they want to use. 18 00:44.480 --> 00:47.680 For example, each of those customers may want to use the 10-10 network. 19 00:47.680 --> 00:51.310 And if that's the case, we need to make sure we're keeping all those routes 20 00:51.310 --> 00:51.920 separate. 21 00:51.920 --> 00:55.520 So all the customer ones routes are kept in a bubble or a container 22 00:55.520 --> 00:58.480 and all the routes for customer two are kept in a separate container. 23 00:58.480 --> 01:02.560 And all the routes for customer three are yet kept in yet a separate container. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 23 00:58.480 --> 01:02.560 And all the routes for customer three are yet kept in yet a separate container. 24 01:02.560 --> 01:04.800 Now, in the world of networking and routing, 25 01:04.800 --> 01:09.120 these logical containers are referred to as a VRF. 26 01:09.120 --> 01:12.640 And that VRF stands for virtual routing and forwarding. 27 01:12.640 --> 01:14.320 That's the VRF portion of it. 28 01:14.320 --> 01:17.120 And that's the concept that we can use inside of NSX 29 01:17.120 --> 01:19.920 to create multiple VRFs, one for each customer. 30 01:19.920 --> 01:23.120 And that way we can keep all their routes separate and unique to them. 31 01:23.120 --> 01:26.780 And then another customer has their own VRF and their own routes and so forth 32 01:26.780 --> 01:27.520 and so on. 33 01:27.520 --> 01:31.520 And in the world of NSX, this is referred to as VRF light. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 33 01:27.520 --> 01:31.520 And in the world of NSX, this is referred to as VRF light. 34 01:31.520 --> 01:35.390 Because although we are using the process of compartmentalizing certain groups 35 01:35.390 --> 01:35.920 of routes, 36 01:35.920 --> 01:40.490 we're not using it with some additional or other features such as MPLS, layer 3 37 01:40.490 --> 01:40.800 VPNs, 38 01:40.800 --> 01:42.320 or other types of services. 39 01:42.320 --> 01:45.600 So the other day, the concept of VRF light in the world of NSX 40 01:45.600 --> 01:49.280 is to keep one customer's route separate from another customer's routes. 41 01:49.280 --> 01:52.460 And in this set of videos, you and I get to walk through the logic of how that 42 01:52.460 --> 01:53.200 's implemented, 43 01:53.200 --> 01:54.880 we'll put a game plan together. 44 01:54.880 --> 01:58.000 And then what you and I get to do is walk through step by step the 45 01:58.000 --> 01:58.960 implementation 46 01:58.960 --> 02:03.280 and verification of VRF light in the world of NSX. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 46 01:58.960 --> 02:03.280 and verification of VRF light in the world of NSX. 47 02:03.280 --> 02:05.760 So I'll see you my friend in the very next video.
