• An application-specific configured router
• Fully integrated DSL/Security/Wireless router
• To support high performance Internet access
High-Availability Features
The Cisco IOS Software Advanced IP Services feature set offers basic and advanced routing capabilities
to deliver failover protection and load balancing . These capabilities include Border Gateway Protocol (BGP),
Open Shortest Path First (OSPF) Protocol, Enhanced Interior Gateway Routing Protocol (EIGRP), and Routing
Information Protocol (RIP) routing protocols along with dial-on-demand routing (DDR) Reliable Static Routing
Using Object Tracking . Each of the Cisco 1800 Series fixed-configuration routers is equipped with either
an ISDN BRI, V . 9 2 analog modem, or Ethernet port for secondary WAN backup connection . If the primary
DSL, cable, or Ethernet-access WAN experiences a link failure or loss of connectivity, the router will detect
this failure and will fail over to the secondary backup WAN . The Cisco 1800 Series fixed-configuration
routers help enable customers to deliver high-performance and high-availability, mission-critical business
applications .
