![]() ![]() Far from being mutually exclusive, Cisco devices, UNIX operating systems, and open source applications can enjoy a peaceful, perhaps even inevitable, coexistence for years to come. For example, the use of UNIX gateways can enable intrusion detection, firewalling, cable and DSL access, terminal servers and access concentrators, VPNs, roaming user support, and other LAN and WAN services. With Cisco Systems routers dominating the Internet and enterprise networking and UNIX routing and gateway solutions spreading from within server farms and data centers, new opportunities and possibilities arise for system and network administrators who understand the benefit of integrated designs. UNIX gateways introduce massive performance possibilities at a fraction of the price of dedicated proprietary appliances by performing network tasks entirely in software. * Explore Linux and BSD networking concepts * Utilize advanced features such as high availability, NAT, bandwidth management, policy routing, and multicast architectures * Understand the way forwarding and signaling are implemented in the UNIX world * Encounter the fascinating world of dynamic UNIX routing and TCP/IP stacks ![]() * Review lab exercises throughout the book that bring concepts to life ![]() * Identify the advantages and disadvantages of Cisco/UNIX integrated designs * Learn how to design, build, and administer integrated gateway routing systems Design, build, and operate integrated gateway routing systems ![]()
