</span>RFC 5281 (EAP-TTLSv0 [1]) only describes the encapsulation of EAP<br>
messages in 'EAP-Message' RADIUS AVPs. Actually, the list of allowed<br>
AVPs is very specific (see section 13). The 'EAP-Payload' Diameter AVP<br>
defined in RFC 4072 (released three years earlier [2]) is not mentioned<br>
at all. And the registry for allowed AVPs was never extended later<br>
either [3]. So it seems what the Cisco ePDG is doing is not RFC compliant.<br>
