SFR France is taking a step forward with its IPv6 addressing migration just in time for this week's IPv6 World Day test flight event.
A key part of this transition includes the deployment of Cisco's (Nasdaq: CSCO) CGv6 solution, which includes its ASR 1000 Series router, a move that will enable it to deliver IPv6-based Internet access for its residential broadband customers.
Because the move to IPv6 from IPv4 is a transition, SFR's IPv6 deployment will incorporate the ASR's Layer 2 Tunneling Protocol (LT2P) that will enable it to simultaneously leverage its existing IPv4 address infrastructure while being able to provide IPv6 services to their customers in a dual-stack mode.
Two of the main advantages of the IPv6 over L2TP approach for SFR and other service providers is it does not require a new capital investment and it does impact existing IPv4 infrastructure in place.
From a residential service perspective, SFR France will enable IPv4/IPv6 services on the customer's home residential gateway. From there, IPv6-enabled sites, including homes will be able to communicate with one another over an IPv4-based core network.
