Orange The RADIUS Attributes suboption, specified in RFC 4014, enables a DHCP relay agent to pass identification and authorization information received during RADIUS authentication to a DHCP server. However, RFC 4014 defines a frozen list of RADIUS attributes that can be included in such a suboption. This document updates RFC 4014 by relaxing that constraint and allowing to tag additional RADIUS Attributes as permitted in the RADIUS Attributes DHCP suboption.
