Emphasize: Distinguish the aspects of the extended IP access list from the standard access list. Your students will perform labs using extended access lists commands. For both standard and extended IP access lists, enter an address mask that identifies which bits in the address field you want the access list to match that will be “don’t care” bit positions. For both types of access lists, the access-group command allows packet filtering into or out of the router.
