The proliferation of the networked economy has spawned fundamental changes in how business is conducted. Running business at Internet speeds has resulted in global expansion, acquisitions, and alliances for many enterprises. Such expansion has placed new demands on the traditional wide-area network (WAN). Networks once focused solely on connecting a few remote sites must now be expanded to accommodate international offices and external business partners. Furthermore, critical business applications have driven the need for ubiquitous connectivity and increased bandwidth to remote locations. Consequently, many enterprises are augmenting or replacing their traditional WANs with site-to-site virtual private networks (VPNs) to better accommodate these new connectivity requirements.The 7204VXR400/T3VPN bundle is best suited for site-to-site VPN services at the enterprise edge with its bundled DS3 interface card. This bundle combines the Cisco VAM encryption performance of greater than full-duplex DS3 line rate with the high bandwidth of a DS3 port adapter. Although the Cisco 7200 Series VPN bundles have been optimized to meet the needs of most LAN-to-LAN and LAN-to-WAN VPN configurations, they can be customized to meet site-specific requirements. For instance, the bundles can be network customized by choosing from a large selection of LAN/WAN port adapters available on the Cisco 7200 Series. Moreover, the bundles can support a larger number of VPN tunnels, by installing more memory, as customer's VPN requirements grow over time.
