ACL Placement: Closer to the Source or Destination? -- Access Control Lists (ACLs) -- Part 8 of 8

Standard ACLs and Extended ACLs are two different tools you can use to identify and filter traffic. When applying them to filter traffic, a decision as to be made as to where they should be applied. In this video, we talk through the different options and shed light on why the following rules end up being the best practice:

Standard ACLs should be applied closest to the Destination
Extended ACLs should be applied closest to the Source

That said, these two rules should be considered as guidelines and not hard-fast rules. There are times when an ACL placement that doesn't follow this logic makes the most sense. That will be unpacked in the video =).
