1.  Introduction

   DHCP (RFC 2131 [2]) provides IP addresses and configuration
   information for IPv4 clients.  It includes a relay agent capability,
   in which processes within the network infrastructure receive
   broadcast messages from clients and forward them to DHCP servers as
   unicast messages.  In network environments like DOCSIS data-over-
   cable and xDSL, for example, it has proven useful for the relay agent
   to add information to the DHCP message before forwarding it, using
