Internet Engineering Task Force (IETF) Z. Cao Request for Comments: 6696 China Mobile Obsoletes: 5296 B. He Category: Standards Track CATR ISSN: 2070-1721 Y. Shi Q. Wu, Ed. Huawei G. Zorn, Ed. Network Zen July 2012 EAP Extensions for the EAP Re-authentication Protocol (ERP) Abstract The Extensible Authentication Protocol (EAP) is a generic framework supporting multiple types of authentication methods. In systems where EAP is used for authentication, it is desirable to avoid repeating the entire EAP exchange with another authenticator. This document specifies extensions to EAP and the EAP keying hierarchy to support an EAP method-independent protocol for efficient re- authentication between the peer and an EAP re-authentication server through any authenticator. The re-authentication server may be in the home network or in the local network to which the peer is connecting. This memo obsoletes RFC 5296.
