The IPsec protocols use a security association, where the communicating parties establish shared security attributes such as algorithms and keys. As such IPsec provides a range of options once it has been determined whether AH or ESP is used.

Internet Key Exchange (IKE) is the protocol Cisco Meraki uses to establish IPSec connections for Non-Meraki site-to-site and client VPNs. When a VPN endpoint sees traffic that should traverse the VPN, the IKE process is then started. IKE is broken down into 2 phases: Phase 1 IPSec and VPNs IPSec is defined by the IPSec Working Group of the IETF. It provides authentication, integrity, and data privacy between any two IP entities. Management of cryptographic keys and security associations can be done manually or dynamically using an IETF-defined key … IPsec VPN Lifetimes - Cisco Meraki IPsec VPNs using IKE utilize lifetimes to control when a tunnel will need to re-establish. When these lifetimes are misconfigured, an IPsec tunnel will still establish …

IPsec & IKE - Check Point Software The goal of the Internet Key Exchange (IKE) is for both sides to independently produce the same symmetrical key. This key then encrypts and decrypts the regular IP packets used in the bulk transfer of data between VPN peers. IKE builds the VPN tunnel by authenticating both sides and reaching an agreement on methods of encryption and integrity.
