High-Performance Architecture for VPNs and Broadband Service

A robust RISC architecture and Cisco IOS features enable the Cisco 1751 Router to support VPN applications with

tunneling and security, as well as DSL, cable, and other broadband access technologies. An internal slot on the Cisco

1751 motherboard supports an optional VPN module that provides hardware-assisted IPSec DES and 3DES

encryption at T1/E1 speeds. The Cisco 1751 Router equipped with the WIC-1ADSL supports VPN over ADSL

service. See Figure 6. The Cisco 1751 Router with the uBR910 series cable DSU supports business-class broadband

cable access. The Ethernet WIC (WIC-1ENET) provides an alternate method of deploying DSL/cable Internet access

with the use of an external modem. In some cases, the ISP provides the broadband modem.

The Cisco 1751Router, deployed in conjunction with the ADSL WIC, enables SMB and small branch customers to reap the beneﬁts of ADSL.

Network Management and Ease of Installation

The Cisco 1751 Router supports a range of network-management and ease-of-installation tools:

•

he Cisco Security Device Manager (SDM) is an intuitive, web-based device management tool embedded within

the Cisco IOS access routers. SDM simpliﬁes router and security conﬁguration through smart wizards to enable

customers to quickly and easily deploy, conﬁgure and monitor a Cisco access router without requiring knowledge

of Cisco IOS Command Line Interface (CLI). For more information visit www.Cisco.com/go/sdm.

• Cisco ConﬁgMaker is a Windows wizard-based tool designed to conﬁgure a small network of Cisco routers,

switches, hubs, and other network devices from a single PC. This tool makes it easy to conﬁgure value-add

security features such as the Cisco IOS Firewall Feature Set, IPSec encryption, and network address translation

(NAT); establish VPN policies (including QoS and security); and conﬁgure the Dynamic Host Conﬁguration

Protocol (DHCP) server.

• CiscoWorks for Windows, a comprehensive network management solution for small to medium sized networks

that provides Web-based network monitoring and device conﬁguration management.

• CiscoWorks2000, the industry-leading Web-based network management suite from Cisco, simpliﬁes tasks such

as network inventory management and device change, rapid software image deployment, and troubleshooting.

• For service providers, Cisco Service Management (CSM) provides an extensive suite of service management

solutions to enable planning, provisioning, monitoring, and billing.
