1.5 Prerequisites/Preconditions

The Extensible Authentication Protocol Method for Microsoft CHAP has no specific prerequisites or preconditions; however, both EAP and MSCHAPv2 have their own prerequisites, as specified in [RFC3748] and [RFC2759], respectively.

For example, MSCHAPv2 depends on the out-of-band establishment of a shared secret between a peer and its authentication server. EAP depends on the out-of-band configuration of which methods are supported by a peer and its EAP server.
