Platform Overview

Series Specications
When to Deploy
Deploy the Cisco 1800 Series fixed-
configuration routers when you need:
• An application-specic congured 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
