IPsec uses four main protocols to create a security framework: Internet Key Exchange (IKE), which makes IPsec more scalable by simplifying the key management; Internet Security Association and Key Management Protocols (ISAKMP), which is the general framework for exchanging keys and is sometimes used as almost a synonym for IKE; Encapsulating Security Protocol (ESP), which is used to provide authentication, integrity checking, and confidentiality to IP packets; and Authentication Header (AH), which is used to provide authentication and integrity checking for IP packets.
You need to know a little bit about each of these, since various choices are available when you configure an IPsec VPN.
