Cisco 7100 Series — VPN Routers

Product Overview

The Cisco 7100 Series VPN Router is a high-end, integrated VPN solution melding high-speed, industry-leading routing with a comprehensive suite of advanced site-to-site VPN services. The Cisco 7100 Series VPN Router integrates key features of VPNs — tunneling, data encryption, security, firewall, advanced bandwidth management (QoS), and service-level validation — to deliver self-healing, self defending VPN platforms that better and more cost-effectively accommodate remote-office and extranet connectivity using public data networks. The Cisco 7100 Series VPN Router offers specific hardware configurations optimized for VPN applications and network topologies. Optional embedded WAN and Fast Ethernet interfaces combined with high-performance routing and rich VPN services provide turnkey VPN routing solutions.

The Cisco 7100 Series encompasses two VPN routers, the Cisco 7120 and the Cisco 7140. The Cisco 7120 is the entry-level Cisco 7100 Series VPN Router, integrating high-performance, industry-leading routing with scalable VPN security and bandwidth management to provide cost-effective, comprehensive VPN solutions for larger branch offices and headquarters. The Cisco 7120 comes in six different models defined by WAN interface. The Cisco 7140 series provides superior routing and VPN services performance for the most demanding VPN deployments, as well as multiport WAN and LAN interfaces and dual power supplies for increased VPN solution flexibility and reliability. The Cisco 7140 comes in seven different models.

Features common to the Cisco 7120 and 7140 include:

• Dual autosensing 10/100BaseT Fast Ethernet ports

• Integrated WAN interface (except the Cisco 7140-2FE model)

• Service module slot, providing a modular architecture for hardware-based VPN services acceleration, such as high-speed IPSec or MPPE encryption provided by the Integrated Services Module

• One expansion slot for interface extensibility, utilizing over 30 Cisco 7xxx port adapters that enable LAN/WAN/voice interface customization for specific site requirements

• 64-MB system memory for reliable, high-speed VPN services delivery---expandable to 256 MB

• 64-MB packet memory for advanced bandwidth management services and long-delay networks

• 48-MB Flash disk for storing Cisco IOS software images---expandable to dual 128 MB Flash disks

• Dual PCMCIA card slots for loading and storing Cisco IOS software configuration files from Flash disk or Flash memory cards

• Low profile, two rack unit design for rack space conservation

• Cisco IOS IP software with VPN tunneling and advanced bandwidth management features included
