About This Product

Product Description:

The Cisco L-FLSASR1-NAT64-2M is a software feature license designed for the Cisco ASR 1000 Series Aggregation Services Routers. This license activates the Stateful NAT64 capability with a capacity of 2,000,000 (2 Million) concurrent sessions.

Stateful NAT64 is a critical technology for IPv4 to IPv6 transition, enabling IPv6-only devices to communicate with IPv4-only servers by maintaining session state information. This high-capacity license is ideal for service providers and large enterprise data centers that require robust, hardware-accelerated translation services to support a large user base during network migration. It is delivered as an electronic Product Authorization Key (PAK).
