The Cisco 1721 Modular Access Router is designed to help organizations embrace the productivity benefits of e-business applications. The Cisco 1721 router enables e-business by delivering secure Internet, intranet, and extranet access with virtual private networks (VPNs) and firewall technology. The Cisco 1721 router offers:
The Cisco 1721 Router delivers a versatile e-business WAN access solution.
Powered by Cisco IOS® Software, the Cisco 1721 router provides a cost-effective solution for small and medium businesses and enterprise small branch offices to support e-business applications through a comprehensive feature set in a compact design.
- A RISC processor to support high-performance routing, encryption, and broadband services
- One autosensing 10/100 Fast Ethernet port
- Two WAN interface card (WIC) slots that support the same data WAN interface cards as the Cisco 1600, 2600, and 3700 routers
- One auxiliary (AUX) port (up to 115.2-kbps asynchronous serial)
- One console port
- One internal expansion slot for the hardware-assisted VPN encryption card (MOD1700-VPN)
- FlexibilityThe modular Cisco 1721 adapts easily to fit the needs of growing businesses. Interchangeable WAN interface cards enable easy additions or changes in WAN technologies without requiring a forklift upgrade of the entire platform. Modular data slots enable users to tailor data services as needed.
- SecurityThe Cisco 1721 supports hardware-assisted wire-speed Triple Digital Encryption Standard IP Security (3DES IPSec) VPN encryption (using optional VPN module), a Cisco IOS Software-based stateful inspection firewall, and an intrusion detection system (IDS) that allows customers to keep their data safe.
- Business-class DSLBusiness-class DSL is delivered through the optional asymmetric DSL (ADSL) or symmetrical high-bit rate DSL (G.shdsl) WICs. The Cisco 1700 Series 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 quality-of-service (QoS) features, performance levels for mission-critical applications and toll-quality voice/data integration are guaranteed.
- Traffic managementThe Cisco 1721 is based on Cisco IOS Software, the accepted standard for Internet operations. Cisco IOS Software allows traffic prioritization by user or application, ensuring that the most strategic e-business applications and time-sensitive applications perform as expected.
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.
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.
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.)
