In this video, you'll learn: - What an Access Control List (ACL) is and what it is used for - How ACLs filter traffic on Cisco routers - The two types of ACLs: Standard and Extended - How ACL rules are processed top-down with an implicit deny at the end - The difference between numbered and named ACLs - How to apply an ACL to an interface — inbound vs outbound direction - Where to place Standard ACLs vs Extended ACLs for best results - How ACLs are used beyond traffic filtering — NAT, route maps, VPNs, QoS ACLs are everywhere in Cisco networking — used for security, traffic management, and as building blocks for advanced features. This video makes sure you understand the fundamentals before moving into configuration and advanced use cases.
