 A Revised Internet-Draft is available from the on-line Internet-Drafts 
 directories. This draft is a work item of the Dynamic Host Configuration 
 Working Group of the IETF.                                                

       Title     : An Inter-server Protocol for DHCP

The DHCP protocol is designed to allow for multiple DHCP servers, so that 
reliability of DHCP service can be improved through the use of redundant 
servers.  To provide redundant service, multiple DHCP servers must carry 
the same information about assigned IP addresses and parameters; i.e., the 
servers must be configured with the same bindings.  Because DHCP servers 
may dynamically assign new addresses or configuration parameters, or extend
the lease on an existing address assignment, the bindings on some servers 
may become out of date.  The DHCP inter-server protocol provides an 
automatic mechanism for synchronization of the bindings stored on a set of 
cooperating DHCP servers.  The underlying capabilities of the DHCP 
inter-server protocol required for multiple server cache replications are 
based upon the Server Cache Synchronization Protocol (SCSP).

Send a message to:  mailserv@ds.internic.net. In the body type: 
     "FILE /internet-drafts/draft-ietf-dhc-interserver-01.txt".
							
NOTE: The mail server at ds.internic.net can return the document in
      MIME-encoded form by using the "mpack" utility.  To use this
      feature, insert the command "ENCODING mime" before the "FILE"
      command.  To decode the response(s), you will need "munpack" or
      a MIME-compliant mail reader.  Different MIME-compliant mail readers
      exhibit different behavior, especially when dealing with
      "multipart" MIME messages (i.e., documents which have been split
      up into multiple messages), so check your local documentation on
      how to manipulate these messages.
							
							

Below is the data which will enable a MIME compliant mail reader 
implementation to automatically retrieve the ASCII version
of the Internet-Draft.
