Your comment implies that ACLs are static and must be configured manually. In this day and age of automated systems, that is no longer true. Anyone who wants to can easily implement dynamic ACLs. They will be slightly less dynamic than a routing protocol, but ACLs do not have to be manually configured and do not have to be static. Of course, on some hardware ACLs have a significant CPU impact, but that is less of a factor than it used to be. --Michael Dillon
