Rebind Capability in DHCPv6 Reconfigure Messages
Abstract
This document updates RFC 3315 (DHCPv6) to allow the Rebind message

message. It extends the Reconfigure message to allow a DHCPv6 server
to cause a DHCPv6 client to send a Rebind message. The document also
clarifies how a DHCPv6 client responds to a received Reconfigure
message.
