ISAKMP, also called IKE (Internet Key Exchange), is the negotiation protocol that allows two hosts to agree on how to build an IPsec security association. ISAKMP negotiation consists of two phases: Phase 1 and Phase 2.   Phase 1 creates the first tunnel, which protects later ISAKMP negotiation messages. Phase 2 creates the tunnel that protects data.  IPSec then comes into play to encrypt the data using encryption algorithms and provides authentication, encryption and anti-replay services.   IPSEC VPN REQUIREMENTS To help make this an easy-to-follow exercise, we have split it into two required steps to get the Site-to-Site IPSec Dynamic IP Endpoint VPN Tunnel to work. These steps are: (1)  Configure  ISAKMP  (ISAKMP Phase 1) (2)  Configure  IPSec   (ISAKMP Phase 2, ACLs, Crypto MAP) Our example setup
