Internet Key Exchange V2 Ipsec Virtual P by Bartlett Graham Inamdar Amjad
IKEv2 IPsec Virtual Private Networks is the first plain English introduction to IKEv2: both a complete primer on this important new security protocol and a practical guide to deploying it with Cisco's FlexVPN implementation. Cisco experts Graham Bartlett and Amjad Inamdar explain how IKEv2 can be used to perform mutual authentication and to establish and maintaining security associations (SAs). Their insights into IKEv2's goals theory and underlying concepts will be invaluable to all network security professionals whatever technologies or solutions they choose for implementation. Next Bartlett and Inamdar thoroughly introduce FlexVPN Cisco's high-value implementation of the IKEv2 standard. You'll discover FlexVPN's unified paradigm and learn how its command-line interface can be used to manage IKEv2 in site-to-site remote access hub and spoke topology and partial mesh (spoke to spoke direct) environments. The authors explain how FlexVPN's simple modular framework relies on the tunnel interface paradigm while remaining compatible with legacy VPN implementations. They offer detailed guidance on configuring IKEv2 VPNs using FlexVPN in both Cisco IOS and IOS-XE environments and show how FlexVPN unifies previous Cisco overlay solutions including crypto maps EasyVPN DMVPN and remote access. Their practical design examples and hands-on troubleshooting steps will help you gain real mastery of FlexVPN configuration and operations in any network environment.
