When to Deploy
Deploy the Cisco 1800 Series
fixed-configuration routers when you need:
• An application-specific configured router
• Fully integrated DSL/Security/Wireless router
• To support high performance Internet access
• High availability Internet connections and load
balancing
• Easy to order products
• Ability to connect several LAN devices
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.92 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.
