Explanation

With EAP, the specific authentication mechanism is not chosen during the link establishment phase of the PPP connection; instead, the PPP peers negotiate to perform EAP during the connection authentication phase. When the connection authentication phase is reached, the peers negotiate the use of a specific EAP authentication scheme known as an EAP method. After the EAP method is agreed upon, EAP allows for an open-ended exchange of messages between the access client and the authenticating server that can vary based on the parameters of the connection. The conversation consists of requests and responses for authentication information. The EAP method determines the length and details of the authentication
