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..
