The Cisco 1720 Modular Access Router and the enhanced Cisco 1721 Modular
Access Router are designed to help organizations embrace the productivity benefits
of e-business applications. The Cisco 1721 and 1720 routers enable e-business by
delivering secure Internet, intranet, and extranet access with virtual private
networks (VPNs) and firewall technology. The Cisco 1721 and 1720 routers offer:
• Wide array of WAN access options,
including high-speed business-class
digital subscriber line (DSL)
• High-performance routing with
bandwidth management
• Inter-virtual LAN (VLAN) routing
(Cisco 1721 only)
• VPN access with firewall option
The Cisco 1721 (shown below in Figure 1)
is an enhanced version of the
award-winning Cisco 1720 Modular
Access Router. The Cisco 1721 offers
higher performance, additional
functionality, and increased memory
capacity over the Cisco 1720. In addition,
the Cisco 1721 supports standards-based
IEEE 802.1Q VLAN routing, which enables
enterprises to set up multiple VLANs and
route between them for added security
within the internal corporate network.
