This is Part 2 of my VIRL series showing you how to download, install and configure Cisco VIRL 2 using VMware Player and Windows 10. The new version of Cisco VIRL allows you to create virtual Cisco networks using just your Web browser. You don't have to use a thick client or any other software - everything is included and everything is easy to use. The new version of Cisco VIRL 2 is one of your best options for CCNA, CCNP and CCIE Labs. VIRL 2 has multiple advantages over other platforms such as GNS3 or EVE-NG. VIRL 2 supports an HTML5 web client and contains all the Cisco IOS images. You don't have to use a thick client like you do with GNS3. You don't have to follow a convoluted process to get Cisco images working like you do with EVE-NG. You don't have to try to find images as they are all included as part of your VIRL subscription and by simply mapping an ISO drive to your virtual machine you can immediately start using all Cisco IOS images in your topologies. Both EVE-NG and GNS3 require that you provide your own IOS images - typically they recommend that you buy a VIRL subscription anyway. That means that you are already paying for VIRL. VIRL2 is also an official Cisco product - that means that you don't have to worry about any gray legal issues with regards to running Cisco IOS images on your laptop. This is an official Cisco product that is supported by Cisco. By paying your yearly subscription fee of $199, you can use Cisco IOS images such as IOSv, IOSvL2, ASAv, NX-OSv and others without any worries. VIRL 2 has everything you need to get started. Disadvantages include the requirement to license your installation. That however has been simplified dramatically from previous releases. There is also a 20 node limited in topologies. However, for most of us that is fine for a lot of labs. Is VIRL better than GNS3 or EVE-NG? In many ways it is. But, all platforms have advantages and disadvantages. If you are studying for your ccie, you many prefer gns3 or eve-ng as they don't limit the number of devices in a topology like virl does. VIRL-PE limits you to 20 devices - so your topologies cannot be massive like they could with gns3 or eve ng. However, if you are studying for your ccna or ccnp, VIRL may be more than enough. Cisco have made massive changes to their certification programs and it is fantastic to see the new version of VIRL in action.

DAI is now part of the CCNA 200-301 exam. You need to know both DAI and DHCP Snooping for the new CCNA exam. Kali Linux can be used to implement an ARP poisoning attack which can result in a man-in-the-middle attack to capture passwords. Stop ARP poisoning attacks by implement Dynamic ARP Inspection. In a previous video I demonstrated how to use Ettercap and Kali Linux to capture usernames and passwords by poisoning the ARP caches of a Windows 10 computer and Cisco router. In this video I'll show you how to stop this type of attack. ARP spoofing attacks and ARP cache poisoning can occur because ARP allows a gratuitous reply from a host even if an ARP request was not received. After the attack, all traffic from the device under attack flows through the attacker's computer and then to the router, switch, or host. An ARP spoofing attack can target hosts, switches, and routers connected to your Layer 2 network by poisoning the ARP caches of systems connected to the subnet and by intercepting traffic intended for other hosts on the subnet. It's so easy to hack badly configured networks using Kali Linux! Ethernet networks rely on protocols such as Address Resolution Protocol (ARP) to function, but they can be easily manipulated using Kali Linux. Make sure you have configured your networks securely! Otherwise, look at how simple it is to hack networks using Kali Linux running on a Windows 10 computer. Applications like Ettercap make hacking with Kali Linux super easy! It's important that you as a network professional know how to protect networks from hackers. Even the new Cisco CCNA 200-301 exam covers some of these hacking topics.

Does the iPhone 11 perform better than an iPhone 10 XS Max and iPhone X when using WiFi 6? What about a PC upgraded to use WiFi 6? Is it worth it upgrading your network to WiFi 6 (802.11ax)? In this video I show you the performance of multiple devices - iPhone 11, iPhone XS Max, iPhone X, iPhone 7 and PC - when using a Netgear Nighthawk AX6000 RAX80 Router. Is wifi 6 better? I think so based on my tests. I am getting over 800 Mbps on a iPhone and over 900 Mbps with a PC. I think that is good performance! However, this is in a test environment - your results may vary depending on where you position the WiFi access point or router and what interference you encounter (thick walls, metal etc). You also need devices that support 802.11ax such as a Galaxy S10 or iPhone 11. Without Wi-fi 6 or 802.11ax support, you may not see much difference in your tests. ======================== Menu: ======================== Overview 0:01 Spoiler results: 2:41 Is is worth buying a wifi 6 router? 3:52 Technical content start: 4:40 Unboxing: 4:57 iPhone 11, XS Max, X, 7 Wifi 6 testing: 9:10 PC WiFi 6 network card testing: 12:58 ======================== Devices used: ======================== Netgear Router: https://amzn.to/2RzHwIB WiFi card: https://amzn.to/3aLpX01 Please note that links listed may be affiliate links and provide me with a small percentage/kickback should you use them to purchase any of the items listed or recommended.
