MicroNugget: How to Configure Extended ACLs on Cisco Routers

Start learning cybersecurity with CBT Nuggets. https://courses.cbt.gg/security In this video, Jeremy Cioara covers extended ACLs on Cisco routers. ACLs are powerful documents that contain lists of statements that govern which devices can and cannot access other devices. By configuring extended ACLs, you can regulate the traffic on a network and keep traffic moving fast and secure. One of the many things that a well-configured extended ACL can do for a network is prevent a given IP address' traffic from reaching another IP address. That's because an extended access list is really nothing more than a document with a row of statements that permit or deny traffic based on rules you can set up. That can be protocol, port number, source, destination, time range, and more. When it comes to configuring an extended ACL, just like driving to Disneyland only to discover it's closed would waste time and energy, the best practice is to host extended access lists as close to the source as possible. See how to write rules that identify source IP, its protocol, and the many other filters you can use to manage network traffic with extended ACLs. 🌐 Download the Free Ultimate Networking Cert Guide: https://blog.cbt.gg/b942 ⬇️ 13-Week Study Plan: CCNA (200-301): https://blog.cbt.gg/8lky Start learning with CBT Nuggets: • Cisco CCNA (200-301) | https://courses.cbt.gg/h6s
