Delivers IPv6 over L2TP while protecting existing IPv4 network investments
SAN JOSE, Calif., 8h June, 2011 – Cisco today announced that SFR France has selected its Carrier-Grade Internet Protocol Version 6 (CGv6) Solutionas a first step in the transition of their network infrastructure to IPv6. SFR, the second largest telecommunications operator in France, has deployed the Cisco ASR 1000 Seriesrouter, enabling IPv6 access to the Internet for residential customers.
SFR required a simple, cost effective solution to transition its IPv4 network to IPv6. The Cisco ASR 1000, utilizing Layer 2 Tunneling Protocol (LT2P), enabled SFR to leverage its existing investment in IPv4 network access infrastructure to quickly provide IPv6 services to their customers.
- Because of the exponential growth of Internet services and increasing number of end users, Service Providers are looking for new ways for their current network architecture to meet the needs of Internet-ready appliances, new applications, and services. IPv6 is designed to enable service providers to meet these challenges and provide new services to their customers. As the number of devices per broadband user exponentially increases worldwide, cable, DSL, Ethernet to the home, wireless, and other always-on access technologies can benefit from the huge address range of IPv6.
- The IPv6 over L2TP approach requires limited investment and impact on existing infrastructure. Dual-stack IPv4/IPv6 services on the Residential Gateway (customer) side are enabled. The solution enables IPv6 sites to communicate with each other over an IPv4 core.The technology significantly reduces the lead-time to IPv6 deployment for service providers while protecting their existing network investment.
- Cisco has taken a leadership position to author and drive an open standard for L2TP, as defined in (RFC 5571), which describers IPv6 global connectivity over an IPv4 core. This document was approved in August 2009 by the Internet Engineering Steering Groupto be published as a Standards Track RFC.
L2TP Softwire Tunnel technology is a component of Cisco's Carrier-Grade IPv6 (CGv6)solution that outlines the three approaches of Preserve, Prepare and Prosper for customers looking to transition to IPv6. The framework was launched in October 2009 with the Cisco CRS family, ASR series and other products supporting this solution.
