The EAP Re-authentication Protocol (ERP) [RFC5296] is designed to allow faster re-authentication of a mobile device that was previously authenticated by means of the Extensible Authentication Protocol [RFC3748]. Given that the local root key (e.g., a DSRK, as described in RFC 5295 [RFC5295]) is generated using the local domain name (LDN), LDN discovery is an important part of re-authentication. As described in RFC 5296 [RFC5296], the LDN to be used in ERP can be learned by the mobile device through the ERP exchange or via a lower- layer mechanism. However, no lower-layer mechanisms for LDN discovery have yet been defined.

The EAP Re-authentication Protocol (ERP) Local Domain Name DHCPv6 Option
In order to derive a Domain-Specific Root Key (DSRK) from the Extended Master Session Key (EMSK) generated as a side effect of an Extensible Authentication Protocol (EAP) method, the EAP peer must discover the name of the domain to which it is attached.
This document specifies a Dynamic Host Configuration Protocol Version 6 (DHCPv6) option designed to allow a DHCPv6 server to inform clients using the EAP Re-authentication Protocol (ERP) EAP method of the name of the local domain for ERP.
