Читать книгу CCNP Enterprise Certification Study Guide: Implementing and Operating Cisco Enterprise Network Core Technologies - Ben Piper, David Higby Clinton - Страница 16

The CCNA certification isn't required to attain the CCNP Enterprise certification. Nevertheless, I strongly recommend that you obtain your CCNA certification or the equivalent experience before embarking on your CCNP Enterprise journey. Refer to the CCNA exam blueprint (www.cisco.com/c/en/us/training-events/training-certifications/certifications/associate/ccna.html) for a full list of topics you should already be familiar with. Because the CCNP Enterprise is a professional-level certification, I don't review some of the basics covered by the CCNA such as subnetting, IPv4, and IPv6 addressing.

You'll need a virtual or physical lab, which you should already have from your previous networking studies. Your lab should be able to support at least eight routers and two layer 3 switches running IOS version 15.2 or later. You should be able to configure your lab on your own by looking at layer 2 and layer 3 diagrams. Topology diagrams will be included in each chapter.

If your existing lab doesn't meet the requirement, Cisco Virtual Internet Routing Lab (http://virl.cisco.com) includes virtual machine images for a variety of switches and routers. These images are virtual machines that run using QEMU and are light on CPU and memory, so you don't need a beast of a server to run simulations, although more resources always help. Other options, although not blessed by Cisco, are GNS3 (https://gns3.com) and EVE-NG (www.eve-ng.net).
