Abstract Abstract
The DHCPv6 RADIUS option provides a mechanism to exchange The DHCPv6 RADIUS option provides a mechanism to exchange
authorization and identification information between the DHCPv6 relay authorization and identification information between the DHCPv6 relay
agent and the DHCPv6 server. This mechanism is meant for the agent and the DHCPv6 server. This mechanism is meant for the
centralized DHCPv6 server to select the right configuration for the centralized DHCPv6 server to select the right configuration for the
requesting DHCPv6 client based on the authorization information requesting DHCPv6 client based on the authorization information
received from the RADIUS server, which is not co-located with the received from the RADIUS server, which is not co-located with the
DHCPv6 server. The Network Access Server (NAS) acts as DHCPv6 relay DHCPv6 server. The Network Access Server (NAS) acts as DHCPv6 relay
