120 - 238 CCNA 2: Routers and Routing Basics v3.1 Instructor Guide – Module 11 Copyright © 2004, Cisco Systems, Inc. 11.1.1 Introduction to ACLs ACLs are lists of conditions that are applied to traffic that travels across a router interface. These lists tell the router what types of packets to accept or deny.
121 - 238 CCNA 2: Routers and Routing Basics v3.1 Instructor Guide – Module 11 Copyright © 2004, Cisco Systems, Inc. If all the ACL statements are unmatched, an implic it "deny any" statement is placed at the end of the list by default.

123 - 238 CCNA 2: Routers and Routing Basics v3.1 Instructor Guide – Module 11 Copyright © 2004, Cisco Systems, Inc. 11.1.4 The function of a wildcard mask A wildcard mask is paired with an IP address. The binary numbers one and zero in the mask are used to identify how the corresponding IP address bits should be handled.
124 - 238 CCNA 2: Routers and Routing Basics v3.1 Instructor Guide – Module 11 Copyright © 2004, Cisco Systems, Inc. To test an ACL, the students will need to know what traffic will be permitted, denied, and the path. Have students test for connectivity, apply the ACL, and then check the ACL to see if it works.
125 - 238 CCNA 2: Routers and Routing Basics v3.1 Instructor Guide – Module 11 Copyright © 2004, Cisco Systems, Inc. 11.2.2 Extended ACLs Extended ACLs are used more often than standard ACLs because they provide a greater range of control.
