The Extensible Authentication Protocol (EAP), defined in [RFC3748], is an authentication framework that supports multiple authentication mechanisms. Today, EAP has been implemented at end hosts and routers that connect via switched circuits or dial-up lines using PPP [RFC1661], IEEE 802 wired switches [IEEE8021X], and IEEE 802.11 wireless access points [IEEE80211i].

            An Extension for EAP-Only Authentication in IKEv2


   IKEv2 specifies that Extensible Authentication Protocol (EAP)    authentication must be used together with responder authentication    based on public key signatures.  This is necessary with old EAP    methods that provide only unilateral authentication using, e.g., one-    time passwords or token cards.

   This document specifies how EAP methods that provide mutual    authentication and key agreement can be used to provide extensible    responder authentication for IKEv2 based on methods other than public    key signatures.
