I took a break from studying for the CCDE to wrap up a new Troubleshooting lab for everyone.  I went ahead and toned down my original CCIE Security Lab (<a rel=\"noreferrer noopener\" href=\"https:\/\/thenetworksdown.com\/?p=5\" target=\"_blank\">available here<\/a>) into a more &#8220;palatable version&#8221; of a practice troubleshooting lab. The focus of this lab is to troubleshoot an Enterprise Network&#8217;s cross section for some fun.  I built this lab to help everyone asses some &#8220;Common Troubleshooting Issues within an Enterprise&#8221; that may (or may not) make themselves known at some point in your networking career.  I am releasing it for free for everyone in EVE-NG format.<\/p>\n\n\n\n<p>As with my last lab, I&#8217;ve attempted to use the Lab Tasks function of EVE-NG, however,<span style=\"text-decoration: underline;\"> <strong>I will also<\/strong> <\/span>make the Workbook available for download via a PDF on this page as well.  <em>See below for the links.<\/em><\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"431\" src=\"https:\/\/thenetworksdown.com\/wp-content\/uploads\/2025\/11\/LAB002-1024x431.png\" alt=\"\" class=\"wp-image-2373\" srcset=\"https:\/\/thenetworksdown.com\/wp-content\/uploads\/2025\/11\/LAB002-1024x431.png 1024w, https:\/\/thenetworksdown.com\/wp-content\/uploads\/2025\/11\/LAB002-300x126.png 300w, https:\/\/thenetworksdown.com\/wp-content\/uploads\/2025\/11\/LAB002-768x323.png 768w, https:\/\/thenetworksdown.com\/wp-content\/uploads\/2025\/11\/LAB002.png 1276w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p><strong>PLEASE READ THE ENTIRE LAB WORKBOOK.<\/strong>  The tasks do not need to be solved sequentially, but there are some interdependent faults within some of the reported tickets.<\/p>\n\n\n\n<p><em><code><span class=\"has-inline-color has-vivid-red-color\"><strong><u>Disclaimer:<\/u>&nbsp; All of the Public\/Private IP space, Public\/Private ASNs, Designs, Naming Schemes, Site Locations, Scenarios, etc. that are in use in this topology were selected at random.&nbsp; If any of the information in this lab overlaps with or resembles that of a production network, it is purely coincidental and is not intentional.&nbsp; <\/strong><\/span><\/code><\/em><a href=\"https:\/\/thenetworksdown.com\/\"><code><span class=\"has-inline-color has-vivid-red-color\"><strong>https:\/\/thenetworksdown.com\/<\/strong><\/span><\/code><\/a><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><em><span style=\"text-decoration: underline;\">Again, some boiler plate question answers<\/span><\/em>:<\/li>\n\n\n\n<li>No, I&#8217;m not quite interested in breaking any NDAs and\/or losing my certs (most of all my &#8220;street cred&#8221;)\u2026 So please, don&#8217;t ask.<\/li>\n\n\n\n<li>The lab is formatted for <strong>EVE-NG<\/strong>.<\/li>\n\n\n\n<li>I have included the Image Names\/Versions I used while creating this lab.<\/li>\n\n\n\n<li><strong><span style=\"color:#c01215\" class=\"has-inline-color\"><span style=\"text-decoration: underline;\">I will not<\/span> <\/span><\/strong>make the Images, BIN files, or any qcow2 files available, Sorry.<\/li>\n\n\n\n<li>Whatever I couldn&#8217;t grab from Cisco&#8217;s site, I was able to get from my Cisco Rep.<\/li>\n\n\n\n<li>The QCOW file for Palo came from their support site.
