FLASR1-CGN-2M

Description

The Cisco FLASR1-CGN-2M is a Right-To-Use (RTU) feature license designed specifically for the ASR1000 series routers, providing Carrier Grade NAT (CGN) capabilities with support for up to 2 million sessions. This license addresses the critical need for IPv4 address conservation in large-scale service provider environments, enabling efficient NAT translation at carrier grade scale.

Key Capabilities

• Activates CGN functionality, including ip nat mode CGN, on ASR1000 platforms.
• Supports high-scale session handling up to 2M concurrent sessions for demanding network deployments.
• RTU licensing model allows for straightforward evaluation and permanent activation without traditional PAK-based right-to-use enforcement.
• Essential for broadband service providers transitioning to IPv6 while maintaining IPv4 compatibility through large-scale NAT.

Platform Integration

This license integrates seamlessly with Cisco ASR1000 series routers, unlocking advanced CGN features when the base IP Base technology package is present. It is particularly noted for deployment on models such as ASR1013 and ASR1002, where users have confirmed its necessity for enabling CGN operations.

Network Benefits

• Mitigates IPv4 address exhaustion by allowing multiple subscribers to share public IPv4 addresses.
• Provides deterministic and scalable NAT translation suitable for high-density subscriber environments.
• Enhances network efficiency in fixed and mobile broadband access networks.
• Supports service provider requirements for logging, analytics, and compliance in CGN deployments.

Deployment of the FLASR1-CGN-2M license empowers network operators to scale their CGN services reliably on proven ASR1000 hardware, ensuring robust performance and feature richness for modern internet peering and customer edge applications.
