Cisco IOS Access Lists takes a methodical approach to access lists and their capabilities, and is ideal for administrators of Cisco equipment configured access lists before but feel as if they do not take full advantage of their capabilities (which, author Jeff Sedayao prove, widespread pass through security). There is an emphasis on minimizing traffic and safety, as the section on how to use access lists to keep routing updates from stub networks exemplifies. Like many books in the series of blue-administrative system, this one includes a lot of explanation about what the capabilities of each, and how each fit with other parts of the system -. David Wall Topics covered: Capabilities and limitations of access lists under the Cisco Internetwork Operating System (IOS) and other similar routing and access-control environment. Access policies (with emphasis on packet filtering), routing policies (via route filtering and route maps), and details of Border Gateway Protocol (BGP), which relates to all access lists.
