Global Configuration Commands

RFC 3315 also describes DHCPv6 Relay Agent interactions, which are very much like DHCPv4 Relay Agent. RFC 3046 describes the DHCPv6 Relay Agent Information Option, which employs very similar capabilities as those described by DHCPv4 Relay Agent Option in RFC 2132.

With the larger address space inherent to IPv6, addresses within a network can be allocated more effectively in a hierarchical fashion. DHCPv6 introduces the notion of “prefix delegation” as described in RFC 3633 as a way for routers to centralize and delegate IP address assignment.
