Relation between EAP and IGMP
According to this article, "Extensible Authentication Protocol (EAP) is the mechanism by which authentication takes place. As the name suggests, it is an extensible protocol. It operates as part of IGMPv3, and is itself an extension to this protocol."
I have not found any valid relation between IGMPv3 and EAP by reading the IGMPv3 standard (RFC 3376). If any of you have any clue about it please add your comment or send me an email.
