Integrated with Cisco IOS XE for easy activation and management
Works with existing security and QoS policies
Scalable licensing model for future growth

Technical Specifications

Compatible hardware: Cisco ASR1000 series (ASR1001, ASR1002, ASR1004, ASR1006)
License type: Feature license (perpetual)
Maximum session capacity: 2 meter sessions
Software requirement: Cisco IOS XE release 16.9 or later

Applications

Service provider networks transitioning customers from IPv4 to IPv6
