The modular design of the Cisco® XR 12000 Series Routers combines shared port adapters (SPAs) and SPA interface processors (SIPs), and enables service prioritization for data, voice, and video services. This extensible design maximizes connectivity options and offers superior service intelligence through programmable interface processors that deliver line-rate performance. Modularity enhances speed-to-service revenue and provides a rich set of quality of service (QoS) features for premium service delivery while effectively reducing the overall cost of ownership. This data sheet contains the specifications for the Cisco XR 12000 Series IPsec VPN Shared Port Adapter.

PRODUCT OVERVIEW
Service providers and enterprises require ubiquitous and secure connectivity to address today's mission-critical, high-bandwidth applications. Many service providers deploy IPsec VPN technology to geographically extend their existing VPNs, and use IPsec to give remote users access to their corporate VPNs. Enterprises replace their traditional WANs with site-to-site and remote-access VPNs with this technology as well. The Cisco XR 12000 IPsec VPN SPA offers next-generation encryption technology and a form factor designed to enable a more flexible and scalable network infrastructure.

The Cisco IPsec VPN SPA delivers scalable and cost-effective VPN performance for Cisco XR 12000 Series Routers. Using the Cisco XR 12000 SIP cards (401, 501, and 601), each slot of the Cisco XR 12000 Series Router can support up to two Cisco IPsec VPN SPAs, or any mixture of the Cisco IPsec VPN SPA with other interface SPA types on the same SIP card. Although the Cisco IPsec VPN SPA does not have physical interfaces, it takes advantage of the breadth of interfaces on the Cisco XR 12000 Series Router.
