High Availability
Cisco 890 Series routers enable customers to deliver high-performance and 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), Multigroup
HSRP (MHSRP), and dial backup with external modem through an virtual auxiliary port. Cisco 890
Series routers are integrated with ISDN BRI (892 model) or a V.92 analog modem (891 model) 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.

Integrated Wireless LAN Capability
The Cisco 890 Series is ideal for enterprise small branch offices and small businesses that need to
be connected to larger enterprise networks. These routers help extend corporate networks to
secure remote sites while giving users access to the same applications found in a corporate office.
They provide increased reliability for diversity of wireless data, voice, and video applications. When
users require WLAN access, visibility and control of network security are even more critical at the
remote site. The Cisco 890 Series meets this need with a single device that combines integrated
802.11a/g/n capabilities with security features such as Wi-Fi Protected Access (WPA), including
authentication with IEEE 802.1X with Cisco Extensible Authentication Protocol (LEAP) and
Protected EAP (PEAP), and encryption with WPA Temporal Key Integrity Protocol (TKIP). The
Cisco 890 Series wireless models that include the integrated access point have full feature parity
