SUMMARY AND CONCLUSION
As companies strive to lower the cost of running their network and increase the productivity of their end users with network applications,
more intelligent branch-office solutions are required. The Cisco 2800 Series offers these solutions by providing enhanced performance and
increased modular density to support multiple services at wire speed. The Cisco 2800 Series is designed to consolidate the functions of many
separate devices into a single, compact package that can be managed remotely. Because the Cisco 2800 Series routers are modular devices,
interface configurations are easily customized to accommodate a wide variety of network applications, such as branch-office data access,
integrated switching, voice and data integration, dial access services, VPN access and firewall protection, business-class DSL, content
networking, intrusion prevention, inter-VLAN routing, and serial device concentration. The Cisco 2800 Series provides customers with the
industry's most flexible, adaptable infrastructure to meet both today's and tomorrow's business requirements for maximum investment
protection.
