I was referring to RFC 3203 (defines DHCPFORCERENEW message), which is the
trigger that signals a host (through its DHCP client) to send a DHCPREQUEST
message to the server.  As far as I know, this feature is not widely
implemented in clients or servers.

Once the client sends the DHCPREQUEST message, all the required DHCP
functions are part of RFCC 2131 and are widely implemented:

* Host sends DHCPREQUEST, as though the host is requesting a lease extension
* Server responds with DHCPNAK
* Host removes current IP address from interface
* Host sends DHCPDISCOVER
* Server responds with DHCPOFFER containing new IP address
* Host sends DHCPREQUEST for new IP address
* Server responds with DHCPACK, completing assignment of new IP address

I don't imply that "not widely implemented" is a reason not to include
DHCPFORCERENEW in the PANA spec (if that is what you had intended).
