Cisco IPsec VTI VPN with IKEv2 and OSPF - IOS 15.2 (Cisco Pocket Lab Guides)

In this lab guide I will be showing you how to configure a Cisco IOS VTI VPN using the following requirements:
-IPsec LAN-LAN VPN tunnel.
-Virtual tunnel interface (VTI)
-Strongest cryptographic algorithms available.
-IKE v2
-AES 256
-SHA 512
-DH group 24
-Pre-shared keys
-OSPF over the VTI tunnel.
I will be using the IOS CLI and not the security device manager (SDM) in this book as it is easier to use and more powerful. The SDM is very useful for management after the IOS router has been configured.
The IOS router will be based upon a 7200VXR with version 15.2 but a lot of the configuration will work on previous versions of the code and on other platforms.
