WEBVTT 1 00:00.000 --> 00:04.880 It's time for us to spend some time reviewing the virtualization technologies 2 00:04.880 --> 00:06.080 we've discussed. 3 00:06.080 --> 00:10.190 Everything from virtualized hosts and virtual machines and virtual switching, 4 00:10.190 --> 00:11.380 importantly, 5 00:11.380 --> 00:16.360 all the way up to talking about virtualization technology we use in networking. 6 00:16.360 --> 00:22.380 So VRFs and then tunnel mechanisms, GRE, IP stack, how do we lock those down? 7 00:22.380 --> 00:27.700 And then VXLAN and LISP, which importantly comes back to our conversation on 8 00:27.700 --> 00:28.360 Cisco's 9 00:28.360 --> 00:32.500 software-defined access, which is kind of why we're talking about VXLAN and LIS WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 9 00:28.360 --> 00:32.500 software-defined access, which is kind of why we're talking about VXLAN and LIS 10 00:32.500 --> 00:32.840 P. 11 00:32.840 --> 00:36.680 So we do want to make sure that we can kind of close that circle here or go, go 12 00:36.680 --> 00:36.680 , 13 00:36.680 --> 00:40.240 go, folks, or however, want to say it, but make sure that we understand not 14 00:40.240 --> 00:40.760 only how 15 00:40.760 --> 00:43.840 these technologies work, but why it matters. 16 00:43.840 --> 00:48.390 Now as part of this skill, what we're really going to focus on is just some 17 00:48.390 --> 00:49.200 making sure 18 00:49.200 --> 00:52.280 we have the knowledge, making sure we understand the concepts. 19 00:52.280 --> 00:56.200 We're going to hit some quiz questions, which will help us to maybe check those 20 00:56.200 --> 00:57.080 recall types 21 00:57.080 --> 00:58.080 of situations. 22 00:58.080 --> 01:01.600 Do I remember the different types of hypervisors, for example? WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 22 00:58.080 --> 01:01.600 Do I remember the different types of hypervisors, for example? 23 01:01.600 --> 01:07.040 Do I remember how much MTU changes with VXLAN, those kinds of things? 24 01:07.040 --> 01:09.830 And then we'll have a couple of scenarios as well, just to make sure that we 25 01:09.830 --> 01:10.000 have a 26 01:10.000 --> 01:14.550 little bit more of an open-ended conversation to ensure that we understand how 27 01:14.550 --> 01:15.400 these concepts 28 01:15.400 --> 01:16.640 come together. 29 01:16.640 --> 01:20.600 The one thing we're not going to do in this skill is jump back into the lab. 30 01:20.600 --> 01:25.550 And the reason for that is simply the labs that were done in those skills, we 31 01:25.550 --> 01:26.160 can just 32 01:26.160 --> 01:27.680 go back and do those anytime. 33 01:27.680 --> 01:30.680 And so that's what I really recommend doing is in order to make sure we WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 33 01:27.680 --> 01:30.680 And so that's what I really recommend doing is in order to make sure we 34 01:30.680 --> 01:31.520 understand the 35 01:31.520 --> 01:36.970 commands we're supposed to be running in order to deploy GRE, to deploy IPsec, 36 01:36.970 --> 01:37.360 all of 37 01:37.360 --> 01:41.800 that, we're not deploying VXLAN or LISP, we just need to understand those 38 01:41.800 --> 01:42.560 concepts. 39 01:42.560 --> 01:46.870 But for the technologies we have to configure, I highly recommend going back in 40 01:46.870 --> 01:47.640 time whether 41 01:47.640 --> 01:52.630 it's now or at the end of the course, whichever one you want, maybe both, but 42 01:52.630 --> 01:53.640 go back to those 43 01:53.640 --> 01:56.240 skills, do those labs again. 44 01:56.240 --> 01:59.820 It's just absolutely mission critical that we'd be able to log into a device 45 01:59.820 --> 02:00.320 and know WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 45 01:59.820 --> 02:00.320 and know 46 02:00.320 --> 02:02.840 how to perform those configurations. 47 02:02.840 --> 02:06.680 And there's no better way to do that than by simply launching the lab and doing 48 02:06.680 --> 02:07.040 those 49 02:07.040 --> 02:08.040 configs. 50 02:08.040 --> 02:10.730 So with that, let's go ahead and jump into some quiz questions and scenarios to 51 02:10.730 --> 02:10.920 help 52 02:10.920 --> 02:12.640 us drive these points home.
