High Availability
Cisco 890 Series Routers enable customers to deliver high-performance, high-availability, mission-critical
business applications (Figure 5). The Cisco IOS Software universal image with Advanced IP Services feature
license (default) offers basic and advanced routing capabilities to deliver failover protection and load balancing.
These capabilities include Virtual Router Redundancy Protocol (VRRP) (RFC 2338), Hot Standby Router Protocol
(HSRP), MultigroupHSRP (MHSRP), and dial backup with external modem through a virtual auxiliary port. Cisco
890 Series Routers are integrated with ISDN BRI (892, 896, and 897 models), a V.92 analog modem (891 model),
or a Gigabit Ethernet port for a secondary WAN backup connection. The Cisco 891F supports both the ISDN BRI
and a V.92 analog modem with a Fast Ethernet port for a secondary WAN backup connection. If the primary
Ethernet-access WAN is disconnected, the router detects this failure and fails over to the secondary backup WAN.
