FlexVPN and L2TPv3 are powerful VPN technologies that provide secure and scalable tunneling solutions for enterprises and service providers. FlexVPN, based on IKEv2, offers a unified framework for remote access, site-to-site, and hub-and-spoke VPNs, simplifying deployment and management while supporting advanced encryption and authentication.
L2TPv3 (Layer 2 Tunneling Protocol Version 3) extends Layer 2 connectivity across IP networks, allowing seamless transport of Ethernet, Frame Relay, or ATM traffic over a secure tunnel. Together, these technologies enable flexible, efficient, and secure network virtualization for diverse use cases.
