Routing And Switching Questions
The main difference between standard and extended ACLs (Access Control Lists) lies in the level of control and granularity they offer in network traffic filtering.
Standard ACLs are based on source IP addresses only and are typically used to permit or deny traffic based on the source IP address. They provide a basic level of control but lack the ability to filter based on other factors such as destination IP address, port numbers, or protocols.
On the other hand, extended ACLs offer more advanced filtering capabilities by allowing control based on source and destination IP addresses, port numbers, protocols, and other factors. They provide a higher level of control and flexibility in defining access policies for network traffic.
In summary, standard ACLs are simpler and limited to filtering based on source IP addresses, while extended ACLs offer more comprehensive filtering options by considering multiple factors such as source and destination IP addresses, port numbers, and protocols.
