1 00:00:02,266 --> 00:00:09,425 [music] 2 00:00:09,425 --> 00:00:13,336 You don't need to have a terminal server - sometimes people 3 00:00:13,336 --> 00:00:16,694 call it an access server - but it's handy. 4 00:00:18,011 --> 00:00:20,884 In case you're not familiar with this term, what is this? 5 00:00:21,419 --> 00:00:26,702 In my office here at INE I've got a little real mini rack I've put together. 6 00:00:26,702 --> 00:00:30,396 It's got, I think, three routers and two switches in it. 7 00:00:30,554 --> 00:00:35,278 And it's useful, but what's irritating to me is that 8 00:00:35,278 --> 00:00:37,829 I don't have a terminal server in that little mini lab. 9 00:00:37,829 --> 00:00:42,687 What that means is when I want to change my console connection I have to 10 00:00:42,687 --> 00:00:47,314 physically turn around, unplug the console port from Switch 1, plug it in Switch 2. 11 00:00:47,314 --> 00:00:50,392 When I'm done with that, unplug it from Switch 2. plug it into Router 1. 12 00:00:50,392 --> 00:00:53,877 I have to physically move the console port around. 13 00:00:53,877 --> 00:00:56,329 Like I said, it's kind of irritating. 14 00:00:56,329 --> 00:01:02,415 If that bothers you, for about $120 to $140 15 00:01:02,415 --> 00:01:05,618 you can buy a Cisco 2509 or 2511. 16 00:01:05,618 --> 00:01:07,397 These are routers that are end-of-sale. 17 00:01:07,396 --> 00:01:09,420 Cisco hasn't sold these in a million years, 18 00:01:09,420 --> 00:01:13,045 but they're still available as used products on eBay and other sites. 19 00:01:13,219 --> 00:01:15,364 And you can use this as a terminal server. 20 00:01:15,560 --> 00:01:20,319 Terminal server is a router that has a bunch of low-speed serial interfaces 21 00:01:20,319 --> 00:01:24,129 and it's got a special cable that comes out of it called an Octal cable. 22 00:01:24,129 --> 00:01:27,016 So you'll need to buy the Octal cable along with this. 23 00:01:27,016 --> 00:01:31,015 An Octal cable, it's a cable that's got a big, fat connector on it. 24 00:01:31,015 --> 00:01:34,682 You plug it in and it's got eight cables that come out of it. 25 00:01:34,682 --> 00:01:39,209 And each one of those cables connects into the console ports 26 00:01:39,209 --> 00:01:41,416 of the various devices you have in your rack. 27 00:01:41,416 --> 00:01:45,488 So what you can do is you can connect to the console port of the terminal server, 28 00:01:45,488 --> 00:01:49,299 and then from there get into the console ports of any of your routers 29 00:01:49,300 --> 00:01:54,238 or switches without physically having to plug and unplug your console cables. 30 00:01:54,303 --> 00:01:56,619 So it's just a convenience device, 31 00:01:56,619 --> 00:02:02,437 but if you've got the money to buy one it certainly will make your life easier. 32 00:02:04,027 --> 00:02:06,336 Don't think about resale value. 33 00:02:08,013 --> 00:02:11,412 Cisco equipment is not an investment. 34 00:02:11,412 --> 00:02:14,635 It's not like buying a house, or diamonds or something. 35 00:02:14,635 --> 00:02:18,394 This stuff goes down in value super-fast. 36 00:02:18,394 --> 00:02:22,327 I mean, you can buy routers out there nowadays for $40 or $50 37 00:02:22,327 --> 00:02:24,830 that when you bought them brand new were $2,000. 38 00:02:24,830 --> 00:02:28,904 So if you plan on reselling this when you're done, 39 00:02:28,904 --> 00:02:30,153 you're going to take a hit. 40 00:02:30,153 --> 00:02:33,292 So if you're spending $500 right now on building your rack, 41 00:02:33,292 --> 00:02:38,026 you might get $150 back when you turn around and sell it, 42 00:02:38,026 --> 00:02:40,555 so just consider that money gone. 43 00:02:43,154 --> 00:02:45,977 Also, don't just take my word for it. 44 00:02:45,977 --> 00:02:49,656 Before you do any of this stuff, research a lot of other articles. 45 00:02:49,656 --> 00:02:54,012 Just google, "build Cisco home lab." 46 00:02:54,012 --> 00:02:56,354 Use those four keywords, "build Cisco home lab," 47 00:02:56,354 --> 00:02:59,951 and you will find lots of articles on there giving various different 48 00:02:59,951 --> 00:03:02,577 piece of advice of how to go about doing this. 49 00:03:02,577 --> 00:03:05,487 I would recommend before you lay down a single penny, 50 00:03:05,487 --> 00:03:09,377 not only watching this video but reading a minimum of three other 51 00:03:09,377 --> 00:03:11,956 articles, just to get a well-rounded advice, 52 00:03:11,957 --> 00:03:13,840 make sure you hit all the bullet points, 53 00:03:13,840 --> 00:03:17,932 then I think you'll be well-prepared to start your planning and your designing. 54 00:03:19,391 --> 00:03:22,211 Lastly, this might happen. 55 00:03:22,211 --> 00:03:24,946 You might have planned as much as possible, 56 00:03:24,945 --> 00:03:27,765 prepared as much as possible, created your spreadsheets, and at the 57 00:03:27,765 --> 00:03:31,653 end of the day, your lab doesn't support something. 58 00:03:31,653 --> 00:03:33,989 There's some feature that you just overlooked, 59 00:03:34,153 --> 00:03:36,608 some interface you neglected to buy. 60 00:03:37,157 --> 00:03:38,725 Don't beat yourself up. 61 00:03:38,725 --> 00:03:40,573 Don't bang your head against the wall. 62 00:03:40,574 --> 00:03:45,170 You could go out and buy another piece of equipment to supplement 63 00:03:45,170 --> 00:03:49,027 your rack to support that feature, but at that point, 64 00:03:49,027 --> 00:03:51,879 if it's just one or two things that your rack isn't supporting, 65 00:03:51,879 --> 00:03:55,892 it might just be more financially beneficial for you to rent some 66 00:03:55,892 --> 00:03:59,865 rack time on INE's rack or somebody else's rack, because maybe 67 00:03:59,865 --> 00:04:04,529 you can just spend three or four hours practicing that one feature, 68 00:04:04,529 --> 00:04:09,954 and that only costs you maybe $100 investment of tokens or something, 69 00:04:09,954 --> 00:04:14,525 which is less than buying the two or three routers, or additional 70 00:04:14,525 --> 00:04:18,059 two or three switches you would need yourself to practice that. 71 00:04:18,059 --> 00:04:19,379 So consider that. 72 00:04:19,379 --> 00:04:23,219 Hopefully your home rack will support pretty much everything you need, 73 00:04:23,219 --> 00:04:25,756 but if it doesn't, you can always supplement 74 00:04:25,768 --> 00:04:27,637 it with rack time somewhere else. 75 00:04:29,043 --> 00:04:30,643 Elizabeth asked a good question. 76 00:04:30,643 --> 00:04:33,618 I'm actually going to make this live, because I want 77 00:04:33,617 --> 00:04:35,972 anybody else to weigh in on this as well. 78 00:04:35,973 --> 00:04:37,999 She says she's a Cisco partner, so that's great. 79 00:04:37,998 --> 00:04:41,329 So Elizabeth, that means you've got access to IOS, which is awesome. 80 00:04:41,436 --> 00:04:44,032 You're looking at building a combination routing and switching 81 00:04:44,032 --> 00:04:47,743 and collaboration home lab. What budget would you recommend? 82 00:04:47,743 --> 00:04:50,794 You don't know the routing and switching side very well. 83 00:04:54,279 --> 00:04:57,581 I don't know collaboration, so I can't speak to that. 84 00:04:57,581 --> 00:05:01,238 So I can't really talk to you about what devices you'll need to buy to 85 00:05:01,238 --> 00:05:07,386 turn this into a collaboration rack, or how much those devices will cost you. 86 00:05:08,518 --> 00:05:12,462 From a routing and switching perspective, 87 00:05:13,344 --> 00:05:19,422 just off the top of my head, I would say for $600 you should be able to 88 00:05:19,422 --> 00:05:22,912 buy a pretty decent routing and switching rack. 89 00:05:22,911 --> 00:05:25,867 A lot of these routers that I showed you that we have in our rack, like 90 00:05:25,867 --> 00:05:33,139 the 2011s and the 1841s, you can buy those for $50 to $80 on eBay. 91 00:05:33,139 --> 00:05:38,832 A lot of the switches you can buy for $120, $130 dollars. 92 00:05:38,832 --> 00:05:41,966 So I'm just estimating that if you buy three switches 93 00:05:41,966 --> 00:05:47,689 and four routers, and the various cables and stuff, and a hub, 94 00:05:47,689 --> 00:05:52,045 you should be able to do all of that for $600 bucks or less - rough estimate. 95 00:05:53,679 --> 00:05:57,132 Somebody else might be able to chime in on what additional things 96 00:05:57,132 --> 00:06:00,338 you'd need for collaboration and how much those might cost you, 97 00:06:00,338 --> 00:06:03,943 if any of those of you who are watching have already gone down that path. 98 00:06:06,664 --> 00:06:16,619 Let's see here. So Mary asks, can you get by with just two 3560s and a 3550, 99 00:06:16,619 --> 00:06:21,000 or would you get rid of the 3550 and get all 3560s? 100 00:06:23,454 --> 00:06:25,078 Short answer is yes. 101 00:06:25,077 --> 00:06:27,191 I think that what you're proposing is fine. 102 00:06:27,191 --> 00:06:33,780 If you have a couple of 3560s, I'd recommend you have at least two 3560s, 103 00:06:33,780 --> 00:06:37,379 and then a third switch can be pretty much whatever you want. 104 00:06:37,379 --> 00:06:40,692 But you are going to want at least two switches that support 105 00:06:40,692 --> 00:06:44,318 your private VLANs, your DHCP snooping and all of that stuff. 106 00:06:44,318 --> 00:06:46,266 You're going to want at least two switches that do that. 107 00:06:46,266 --> 00:06:49,709 Ideally three, but if you've already got a 3550, 108 00:06:49,709 --> 00:06:53,450 or if you can get your hands on a 3550, that's fine. 109 00:06:53,450 --> 00:06:56,464 That'll be fine for your third switch, because that can still do routing. 110 00:06:56,464 --> 00:06:59,480 3550s can still do your EIGRP, and OSPF 111 00:06:59,480 --> 00:07:02,478 and stuff like that, they just can't do some of the more advanced 112 00:07:02,478 --> 00:07:05,982 security features, but if you've got two other switches that can, 113 00:07:05,982 --> 00:07:07,249 that should be good enough. 114 00:07:07,249 --> 00:07:08,690 So that's fine. 115 00:07:08,899 --> 00:07:12,510 Someone's asking about the CCIE level. 116 00:07:12,510 --> 00:07:17,525 When I was practicing for my CCIE, I basically used a rack that was 117 00:07:17,525 --> 00:07:21,261 similar to what we have here - that had four or five routers in it 118 00:07:21,261 --> 00:07:24,284 and three switches - and I found that to be perfectly sufficient. 119 00:07:24,284 --> 00:07:28,202 This is, of course, talking about the routing and switching CCIE. 120 00:07:29,771 --> 00:07:33,673 Here at INE, of course, if you log into our INE CCIE racks, 121 00:07:33,673 --> 00:07:35,704 which I'll show you when we get to part two here, 122 00:07:35,704 --> 00:07:40,801 they're much larger topologies - which is great, gives you a lot of flexibility. 123 00:07:40,801 --> 00:07:44,155 But if you're building your own home lab, 124 00:07:44,308 --> 00:07:49,793 you don't need to build a home lab that's got 10 or 15 routers in it and 8 switches. 125 00:07:49,793 --> 00:07:56,863 Great if you can, but, I think, for CCIE level, 126 00:07:56,863 --> 00:08:01,775 you'd probably want an absolute minimum of five routers. 127 00:08:01,775 --> 00:08:05,566 I can't see being able to do some of the more complex filtering and 128 00:08:05,567 --> 00:08:10,969 summarization and redistribution topologies with anything less than 129 00:08:10,969 --> 00:08:15,522 five routers, and a minimum of three switches. 130 00:08:15,522 --> 00:08:19,066 Keep in mind, if those three switches are full multilayer switches, 131 00:08:19,066 --> 00:08:22,738 you've basically got a topology of eight routers - five routers and 132 00:08:22,738 --> 00:08:24,859 three multilayer switches gives you eight routers, 133 00:08:24,859 --> 00:08:26,578 and you can do all kinds of stuff with that. 134 00:08:26,578 --> 00:08:29,252 I would say that's the minimum. And that should be fine 135 00:08:29,252 --> 00:08:32,404 for doing all of your routing and switching CCIE level stuff. 136 00:08:33,293 --> 00:08:36,476 Someone's mentioning that their V4 CCIE routing and 137 00:08:36,476 --> 00:08:39,422 switching home lab cost them $2000. 138 00:08:39,422 --> 00:08:44,945 I'd be curious, Howard, if you could tell us the quantity of routers 139 00:08:44,945 --> 00:08:48,676 and switches that you have in your lab that led up to that, 140 00:08:48,675 --> 00:08:53,012 and also if all that stuff was used or if you bought any of that 141 00:08:53,013 --> 00:08:56,108 stuff new. Certainly new stuff will ratchet up the price very, 142 00:08:56,108 --> 00:08:58,451 very quickly. Ah, Michael's got a good point here. 143 00:08:58,451 --> 00:09:00,623 I'll make sure this is all visible. 144 00:09:00,623 --> 00:09:05,339 He says, for Cisco partners there is the NFR program, 145 00:09:05,436 --> 00:09:10,292 where you can get some devices refurbished from Cisco direct at a steep discount. 146 00:09:10,292 --> 00:09:12,508 So for those of you who are Cisco partners that's also something 147 00:09:12,507 --> 00:09:14,212 you might want to look into as well. 148 00:09:14,213 --> 00:09:15,825 Yeah, John has a good point. 149 00:09:15,825 --> 00:09:19,338 If you buy a router as a terminal server, that's another router. 150 00:09:19,338 --> 00:09:21,887 Not only do you have that octal cable coming out to connect 151 00:09:21,887 --> 00:09:25,195 to the console ports, but that terminal server should have probably 152 00:09:25,195 --> 00:09:28,542 at least two FastEthernet interfaces in it. 153 00:09:28,541 --> 00:09:32,674 So that's another router that you can add into your topology. Exactly, exactly. 154 00:09:32,823 --> 00:09:38,151 3750s are great. Yes, certainly, if you can have a stack of two or 155 00:09:38,151 --> 00:09:42,668 three 3750s, now you can practice switch stacks as well. 156 00:09:42,668 --> 00:09:46,273 That's also going to require that you buy that special stack cable. 157 00:09:47,037 --> 00:09:51,002 I've never looked for that on eBay. I'm sure somebody sells that used as well. 158 00:09:51,538 --> 00:09:53,951 So 3750s, they're a little bit pricier. 159 00:09:53,951 --> 00:09:58,693 So 3750s, even used, cost a little bit more than 3560s do. 160 00:09:58,693 --> 00:10:03,599 So you have to ask yourself, is that additional benefit of doing switch stacking 161 00:10:03,599 --> 00:10:10,768 worth the extra $40 to $60 per switch that I'm going to spend? It's your choice. 162 00:10:10,965 --> 00:10:14,885 Jeremy's mentioning, the backbone router ID has always confused me. 163 00:10:14,885 --> 00:10:17,295 What is the purpose, to serve as a WAN? 164 00:10:17,294 --> 00:10:19,066 Should this be connected to the Internet? 165 00:10:19,066 --> 00:10:26,624 So, here when you log into, not just INE's racks, 166 00:10:26,624 --> 00:10:33,449 but most companies that give you the ability to purchase time on their 167 00:10:33,449 --> 00:10:40,302 racks, usually will have at least one router that's called a backbone router. 168 00:10:40,558 --> 00:10:44,553 The purpose of the backbone router is, when you log into the rack, 169 00:10:45,011 --> 00:10:48,276 you will have access to some routers and switches that you can 170 00:10:48,276 --> 00:10:49,834 pretty much do anything on. 171 00:10:49,834 --> 00:10:52,306 You can configure it, you can wipe out the configuration, 172 00:10:52,306 --> 00:10:53,537 you can do whatever. 173 00:10:53,659 --> 00:10:55,491 But they are probably going to want to have, 174 00:10:55,491 --> 00:11:00,183 in the background, other routers, maybe switches, 175 00:11:00,183 --> 00:11:01,984 that you don't have access to. 176 00:11:01,983 --> 00:11:03,005 Like in our case. 177 00:11:03,006 --> 00:11:05,519 In our CCNA/CCNP rack. 178 00:11:05,797 --> 00:11:11,527 One of our backbone routers is configured as a frame relay switch. 179 00:11:11,649 --> 00:11:15,402 So it's always preconfigured with PBCs, with DLCI numbers. 180 00:11:15,402 --> 00:11:19,553 We don't want you to have access to that, because that one router 181 00:11:19,553 --> 00:11:23,914 is serving as a frame relay switch for lots of different racks. 182 00:11:23,914 --> 00:11:27,946 There's five different racks that all feed into that one frame relay 183 00:11:27,946 --> 00:11:31,131 switch, and so we don't want people getting in there and messing it up. 184 00:11:31,380 --> 00:11:34,728 There's another backbone router that's in the rack which is being 185 00:11:34,728 --> 00:11:37,806 used to inject routes into your rack. 186 00:11:37,805 --> 00:11:43,851 So for example, when you're going through the route workbook, 187 00:11:43,851 --> 00:11:48,126 when you're doing the EIGRP and the OSPF tasks, you will notice that 188 00:11:48,126 --> 00:11:51,888 once you configure EIGRP and OSPF all of a sudden magically you're 189 00:11:51,888 --> 00:11:55,885 seeing EIGRP routes, and you're seeing OSPF routes, because that backbone 190 00:11:55,885 --> 00:11:58,886 router in the background is injecting that in there. 191 00:11:58,886 --> 00:12:02,412 And we don't want you having access to that to mess that up, because that's 192 00:12:02,412 --> 00:12:05,052 not only serving your rack, but other people as well. 193 00:12:05,053 --> 00:12:08,516 So usually the concept of a backbone router is simply, it's a device 194 00:12:08,516 --> 00:12:12,607 that is untouchable by you, that's been pre-configured by somebody 195 00:12:12,608 --> 00:12:16,040 else to inject something into your rack. 196 00:12:16,040 --> 00:12:19,030 Now, certainly, if you're building a home-based lab, 197 00:12:19,399 --> 00:12:21,114 you don't need that concept. 198 00:12:21,114 --> 00:12:23,041 You're going to have access to everything. 199 00:12:23,041 --> 00:12:26,743 So a backbone router is really only something you would see conceptually 200 00:12:26,743 --> 00:12:29,621 in remote racks that you're logging into. 201 00:12:31,288 --> 00:12:34,102 John asks a good question right here. 202 00:12:34,102 --> 00:12:37,801 How do you switch back and forth between console access and being 203 00:12:37,801 --> 00:12:39,202 on the actual network? 204 00:12:39,558 --> 00:12:41,788 Two cables are going to the terminal router. 205 00:12:41,788 --> 00:12:48,799 In my particular case, when I'm doing it here in my office-- your 206 00:12:48,799 --> 00:12:52,367 laptop has probably a WiFi connection. 207 00:12:52,367 --> 00:12:55,713 I use WiFi here while I'm on the actual network, and my 208 00:12:55,712 --> 00:12:58,441 console connections via my USB port. 209 00:12:58,441 --> 00:13:03,086 So it's two completely different interfaces on my laptop. 210 00:13:03,086 --> 00:13:08,461 I'm doing just asking and doing regular text through the USB port as console, 211 00:13:08,461 --> 00:13:11,327 but all of my frame data, my Ethernet frames going to the 212 00:13:11,327 --> 00:13:14,481 corporate network are either going through my Ethernet cable, 213 00:13:14,481 --> 00:13:17,426 which connects to the corporate network, or via WiFi. 214 00:13:17,426 --> 00:13:19,381 So the two are completely different, 215 00:13:19,381 --> 00:13:21,807 my laptop does not get confused. 216 00:13:23,012 --> 00:13:27,285 John asked, would you advise purchasing a terminal server over 217 00:13:27,285 --> 00:13:29,222 a console access server? 218 00:13:29,222 --> 00:13:33,286 I'm personally not exactly sure what the difference is between the two. 219 00:13:33,286 --> 00:13:37,298 In my mind, I've seen people interchangeably use the term, 220 00:13:37,298 --> 00:13:39,825 terminal server and access server. 221 00:13:40,523 --> 00:13:44,045 Back when I worked at Cisco, in our labs, 222 00:13:44,045 --> 00:13:47,673 our 2509s and our 2511s, we called them terminal servers. 223 00:13:47,673 --> 00:13:49,203 That's what connected the console ports. 224 00:13:49,203 --> 00:13:52,029 When I came here to INE, the racks we have here, 225 00:13:52,029 --> 00:13:54,936 they call them access servers. 226 00:13:54,936 --> 00:13:58,462 So, I'm not sure if you're thinking of something else. 227 00:13:58,687 --> 00:14:00,173 Okay, great, Howard. 228 00:14:00,173 --> 00:14:03,342 So I'll make that visible there. So Howard had previously mentioned that 229 00:14:03,341 --> 00:14:08,100 his CCIE rack that he built cost roughly two grand, and right there 230 00:14:08,100 --> 00:14:10,747 he's mentioning what that rack consisted of. 231 00:14:10,747 --> 00:14:14,157 So for those of you who are watching this recorded a month or six 232 00:14:14,157 --> 00:14:18,095 months from now, so Howard built a rack consisting of it looks like 233 00:14:18,094 --> 00:14:23,501 roughly four switches, a couple 3560s, a couple of 3750s. 234 00:14:24,133 --> 00:14:32,346 He had three 1841s, two 3825s, four 2600 XM. So you basically had 235 00:14:32,346 --> 00:14:35,945 four, five, six. So you had nine routers. 236 00:14:36,210 --> 00:14:39,773 And then you had a 2511 as an access server. 237 00:14:41,386 --> 00:14:44,238 And then a couple of actual racks as well. 238 00:14:44,238 --> 00:14:49,482 So you had nine routers, four switches and an access server, 239 00:14:49,482 --> 00:14:51,896 and that cost you roughly $2,000. 240 00:14:54,636 --> 00:15:00,777 Alfonzo, I don't have any answer for you about the CCIE security path, 241 00:15:00,777 --> 00:15:04,488 because I have not pursued that certification, so maybe somebody 242 00:15:04,489 --> 00:15:07,399 else can chime in on that, but I'm not sure what hardware you would 243 00:15:07,399 --> 00:15:11,732 need to build a rack for that. 244 00:15:12,956 --> 00:15:19,966 John clarified his question. So John was wondering, if I want to use 245 00:15:19,966 --> 00:15:25,430 my laptop for two things, if I want my laptop on the one hand to 246 00:15:25,430 --> 00:15:29,445 be sending actual data into my rack, maybe I'm using some package 247 00:15:29,445 --> 00:15:32,407 generator software and I want to send data into my rack, 248 00:15:32,407 --> 00:15:38,154 and at the exact same time I want my laptop to have actual real internet 249 00:15:38,154 --> 00:15:44,013 access to my DSL modem or something, how do I do that? 250 00:15:45,363 --> 00:15:49,898 The way I have done it in the past is I use my hard-wire Ethernet 251 00:15:49,898 --> 00:15:53,746 cable to connect to my rack, and that's where I did like my package 252 00:15:53,746 --> 00:15:58,278 generation stuff. I use my WiFi connection to connect to my home 253 00:15:58,278 --> 00:16:02,463 WiFi network, and what you have to tweak is you actually have to 254 00:16:02,463 --> 00:16:05,742 go into-- let me see here if I can show it to you. 255 00:16:06,409 --> 00:16:09,425 I can only speak to Microsoft here, I can't speak to those 256 00:16:09,425 --> 00:16:11,760 of you who are using MACs. 257 00:16:13,193 --> 00:16:16,726 But here, and I think you'll see it, 258 00:16:16,727 --> 00:16:19,510 if I use the command-- let me expand this a little bit. 259 00:16:19,868 --> 00:16:24,234 If I use the command route print scroll up. 260 00:16:24,234 --> 00:16:28,036 So right now my laptop actually does have a hard-wired Ethernet connection 261 00:16:28,036 --> 00:16:32,333 into INEs corporate network, and I also have a Wi-Fi connection 262 00:16:32,333 --> 00:16:33,805 into INEs corporate network. 263 00:16:33,805 --> 00:16:37,991 And you'll see I have two default routes. 264 00:16:38,891 --> 00:16:44,851 So what you'd want to do is, in your particular case, if my hard-wired 265 00:16:44,851 --> 00:16:49,607 Ethernet connection was going to my rack, I'd want to make sure that 266 00:16:49,607 --> 00:16:54,085 my default route I only had one of them, and that my default 267 00:16:54,085 --> 00:16:57,114 route was pointing to my Wi-Fi connection. 268 00:16:57,414 --> 00:17:03,637 So you'd want to use like the route delete command in DOS to delete 269 00:17:03,637 --> 00:17:06,916 the default route that's pointing out your Ethernet cable, because in 270 00:17:06,916 --> 00:17:11,567 reality, that's not a valid default route to get to external networks. 271 00:17:11,566 --> 00:17:13,789 That's only going to your own internal network. 272 00:17:13,789 --> 00:17:18,630 So as long as you delete that, and then you might want to add a static 273 00:17:18,631 --> 00:17:23,669 route in DOS into the network you've got built into your home lab. 274 00:17:23,669 --> 00:17:28,428 And then just keep one single default route, which is the default 275 00:17:28,428 --> 00:17:31,288 route pointing out your WiFi connector, which gives you 276 00:17:31,288 --> 00:17:34,019 your actual real internet connectivity. 277 00:17:34,019 --> 00:17:36,158 So that's how you want to accomplish that. 278 00:17:36,577 --> 00:17:39,319 Can't speak to how pricey a basic voice lab. 279 00:17:39,319 --> 00:17:40,744 That goes back to collaboration. 280 00:17:40,744 --> 00:17:45,509 Somebody else was asking how much a collaboration lab would cost. 281 00:17:46,206 --> 00:17:49,458 One other question and then we'll take a break here. 282 00:17:49,458 --> 00:17:53,047 So Steven's asking, is it worth mentioning talking about an IP power 283 00:17:53,047 --> 00:17:56,824 distribution unit, so you can power cycle remotely? 284 00:17:57,483 --> 00:17:58,854 That's really your choice. 285 00:17:59,781 --> 00:18:01,650 You have to ask yourself this question, 286 00:18:01,650 --> 00:18:06,473 do you foresee that once you've got this lab built and running in 287 00:18:06,473 --> 00:18:10,011 your house - in your bedroom, your garage, 288 00:18:10,011 --> 00:18:14,489 or wherever it's going to be - do you foresee yourself needing 289 00:18:14,489 --> 00:18:16,213 to access this lab remotely? 290 00:18:16,213 --> 00:18:19,773 Do you foresee yourself working from your actual office 291 00:18:19,773 --> 00:18:21,755 and needing to get into this lab? 292 00:18:21,755 --> 00:18:24,372 If the answer to that is yes, then yeah, 293 00:18:24,371 --> 00:18:29,021 you'll probably want to get an IP power distribution unit so you 294 00:18:29,021 --> 00:18:31,334 can remotely power cycle your equipment. 295 00:18:31,486 --> 00:18:33,439 If you don't think you're ever going to need that, 296 00:18:33,439 --> 00:18:36,423 if you say to yourself, Well, the only time I'm ever going to access 297 00:18:36,423 --> 00:18:38,591 this equipment is actually when I'm right there physically in 298 00:18:38,591 --> 00:18:41,783 front of it, then no, you obviously wouldn't need that. 299 00:18:42,549 --> 00:18:46,698 The other thing is, if you are going to access your lab remotely, 300 00:18:46,698 --> 00:18:52,341 now you've got to think about, Okay, my terminal server is probably 301 00:18:52,341 --> 00:18:54,999 now going to become a necessity. It's no longer optional, 302 00:18:54,999 --> 00:18:58,371 I'm going to have to have one. And that terminal server is going to 303 00:18:58,371 --> 00:19:05,472 have to have a public IP address so I can get to it from the outside world. 304 00:19:05,472 --> 00:19:08,863 That opens up a whole other ball of worms, is how you get a 305 00:19:08,863 --> 00:19:12,910 public static IP address on your terminal server so you can get to it 306 00:19:12,910 --> 00:19:17,517 from your office, or from when you're vacationing in Hawaii or whatever. 307 00:19:17,517 --> 00:19:21,240 So that's also something you'd have to think about is how to accomplish that. 308 00:19:21,240 --> 00:19:26,013 [music]
