Cisco® 890 Series Integrated Services Routers combine Internet access,
comprehensive security, and wireless services in a single, secure device that is easy
to deploy and manage (Figure 1). The best-in-class Cisco 890 Series architecture is
specifically designed to deliver high performance with concurrent services, business
continuity, and investment protection for enterprise small branch offices and service
provider-managed services applications.

Product Overview
Cisco 890 Series Integrated Services Routers (ISRs) are fixed-configuration routers that provide collaborative
business solutions for secure voice and data communications to enterprise small branch offices (Figure 2). They
are designed to deliver secure broadband, Metro Ethernet, wireless LAN (WLAN) connectivity, and business
continuity. The routers also come with powerful management tools, such as the web-based Cisco Configuration
Professional configuration management tool, which simplifies setup and deployment. Centralized management
capabilities give network managers visibility and control of the network configurations at the remote site.
Cisco 890 Series Integrated Services Routers offer the following:
●
The routers offer high performance for secure broadband and Metro Ethernet access with concurrent
services for enterprise small branch offices.
●
They provide business continuity and WAN diversity with redundant WAN links: Fast Ethernet (FE), V.92,
ISDN Basic Rate Interface (BRI), Gigabit Ethernet (GE), ADSL2+/VDSL (Annex A/B/M), Multimode
G.SHDSL, and Small Form-Factor Pluggable (SFP).
●
An integrated secure 802.11a/g/n access point (optional) is based on the draft 802.11n standard. Dual-band
radios allow for mobility and support for autonomous or Cisco Unified WLAN architectures.

Architecture Features and Benefits
Secure Network Connectivity
Cisco 890 Series Routers deliver high performance with integrated security and threat defense. Network security
has become a fundamental building block of any network, and Cisco routers play an important role in embedding
security at the customer’s access edge. Cisco recognizes this requirement, so Cisco 890 Series Routers are
equipped with security hardware acceleration and Cisco IOS Software (by default, a universal image with
Advanced IP Services feature license). This Cisco IOS Software feature set facilitates hardware-based IPsec
encryption on the motherboard and provides a robust array of security capabilities such as Cisco IOS Firewall,
Cisco ScanSafe Connector, IPS support, IPsec VPNs (DES, 3DES, and AES), SSL VPN, tunnel-less Group
Encrypted Transport VPN, DMVPN, Easy VPN server and client support, Secure Shell (SSH) Protocol Version 2.0,
and Simple Network Management Protocol (SNMP) in one solution set.
Cisco 890 Series Routers come with a comprehensive security solution that protects organizations’ networks from
known and new Internet vulnerabilities and attacks while improving employee productivity. Security suite also
includes the following:
●
FlexVPN: Large customers deploying IPsec VPN over IP networks are faced with high complexity and high
cost of deploying multiple types of VPN to meet different types of connectivity requirements. Customers
often have to learn different type of VPNs to manage and operate different types of networks. And when a
technology is selected for a deployment, migrating or adding functions to enhance the VPN is often avoided.
FlexVPN was created to simplify the deployment of VPN and address the complexity of multiple solutions,
and, as a unified ecosystem, to cover all types of VPNs: remote-access, teleworker, site-to-site, mobility,
managed security services, and others.
●
Next-generation encryption (NGE): Traditional encryption standards (Internet Key Exchange Version 1
[IKEv1], Secure Hash Algorithm1 [SHA-1], etc.) were developed more than a decade ago. They are no
longer considered as secure as before. NGE is meant to refresh the existing security protocols to the next
level based on the standard Suite-B algorithms such as SHA-2, AES-Galois Counter Mode (AES-GCM),
Elliptic Curve Diffie-Hellman (ECDH), Elliptic Curve Digital Signature Algorithm (ECDSA), IKEv2, etc. NGE
offers customers secure network communications systems that will be reliable for the next decade.
●
Cisco ISR Web Security with Cisco ScanSafe: Cisco Cloud Web Security is a cloud-based service designed
to prevent zero-day malware from reaching corporate networks, including roaming or mobile users. The
Cisco ScanSafe Cloud Web Security solution requires no hardware, initial capital costs, or maintenance and
provides unparalleled real-time threat protection (Figure 3). This solution is scalable and easy to maintain,
and is ideally suited for small businesses and enterprise small branch offices.

Metro Ethernet Connectivity
Cisco 890 Series Routers are ideal for service provider deployments as Metro Ethernet customer premises
equipment (CPE). The routers also provide failover protection and load balancing. The 8-port managed switch
provides enough LAN ports for connecting multiple devices, and the optional PoE capability can supply power to IP
phones or other devices. The Cisco 890 Series offers customers significant value by simplifying deployment of
Ethernet WAN services with end-to-end OA&M, service-level agreement (SLA) monitoring and verification, and
configuration management, resulting in increased operational efficiency and reduced operating expenses (OpEx).
The Cisco 890 Series supports the following Metro Ethernet features:
●
E-LMI: Basic configuration for detection and isolation of connectivity in the Metro Ethernet network
●
E-LMI: Automated configuration of customer edge based on profiles configured:
◦ Layer 2 connectivity management
◦ E-LMI for the customer edge
●
Metro Ethernet OA&M:
◦ Debugging hierarchy of Ethernet networks
◦ Layer 2 service performance monitoring
●
802.1agCFM:
◦Standard that uses domains to contain OA&M flows and bound OA&M responsibilities
●
802.3ah: Ethernet in the First Mile (EFM)
◦Three types of packets: Continuity Check, Layer 2 Ping, and Layer 2 Traceroute
●

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.
