The Cisco 1721 router offers the following key features:

The Cisco 1700 Series supports the value of end-to-end Cisco network solutions with the following benefits:

E-Business Applications

VPN and Security

The Cisco 1721 router is part of the end-to-end Cisco VPN solution. VPNs create secure connections via the Internet to connect geographically dispersed offices, business partners, and remote users while providing security, traffic prioritization, management, and reliability equal to that of private networks.

By supporting industry standards, IPSec, Layer 2 Tunneling Protocol (L2TP), and DES and 3DES, the Cisco 1721 router delivers robust VPN solutions to ensure data privacy, integrity, and authenticity.

The optional VPN hardware encryption module for the Cisco 1721 router further optimizes VPN encryption performance. By offloading encryption tasks to the VPN module, the router processor is freed to handle other operations. The VPN module accelerates the rate at which encryption occurs, speeding the process of transmitting secure data, a critical factor when using 3DES encryption.

The Cisco 1721 router offers integrated security features, including stateful inspection firewall functionality and IDS as an optional Cisco IOS Software feature. By deploying Cisco IOS Software firewall functionality, customers do not need to purchase or manage multiple devices, thus simplifying network management and reducing capital costs. Additionally, remote management applications, such as Cisco Security Device Manager (SDM), make it easier than ever to deploy and monitor Cisco IOS Firewall and VPN on your Cisco 1721 router.

Cisco IOS Software firewall security features include access control lists (ACLs), user Authentication, Authorization, and Accounting (such as Password Authentication Protocol/Challenge Handshake Authentication Protocol [PAP/CHAP], TACACS+, and Remote Access Dial-In User Service [RADIUS]). These security features provide the optimal level of firewall protection to customers.

The Cisco 1700 Series routers support the Cisco Easy VPN Remote feature that allows the routers to act as remote VPN clients. As such, these devices can receive predefined security policies from the headquarters' VPN head-end, thus minimizing configuration of VPN parameters at the remote locations. This solution makes deploying VPN simpler for remote offices with little IT support or for large deployments where it is impractical to individually configure multiple remote devices. While customers wishing to deploy and manage site-to-site VPN would benefit from Cisco Easy VPN Remote because of its simplification of VPN deployment and management, managed VPN service providers and enterprises who must deploy and manage numerous remote sites and branch offices with Cisco IOS routers for VPN will realize the greatest benefit.

The Cisco 1700 Series routers also support the Cisco Easy VPN Server feature that allows a Cisco 1700 router to act as a VPN head-end device. In site-to-site VPN environments, the Cisco 1700 router can terminate VPN tunnels initiated by the remote office routers using the Cisco Easy VPN Remote. Security policies can be pushed down to the remote office routers from the Cisco 1700 router. In addition to terminating site-to-site VPNs, a Cisco 1700 router running the Unified VPN Access Server can terminate remote access VPNs initiated by mobile and remote workers running Cisco VPN client software on PCs. This flexibility makes it possible for mobile and remote workers, such as sales people on the road, to access company intranet where critical data and applications exist.

Business-Class DSL

The Cisco 1721 router supports business-class DSL through the optional ADSL or G.shdsl WICs.

The Cisco 1721 business-class DSL solution combines the cost benefits of DSL service with the advanced routing capability required for business use of the Internet. Through enhanced DSL QoS features, performance levels for mission-critical applications are guaranteed. (See Figure 2.)

Figure 2
The Cisco 1700 Series Deployed with an ADSL WIC

When equipped with optional Ethernet WICs, the Cisco 1700 Series supports a two- or three-Ethernet configuration, enabling deployment with an external broadband modem (such as DSL, cable modem, or wireless modem)—often supplied by a service provider as a demarcation point and deployment of a demilitarized zone (DMZ). (See Figure 3.)
