	Title           : Virtual Subnet Selection Sub-Option for the Relay Agent Information Option for DHCPv4

In some environments, a relay agent resides in a network element
which also has access to one or more virtual private networks (VPNs).
If a DHCP server wishes to offer service to DHCP clients on those
different VPNs the DHCP server needs to know information about the
VPN on which each client resides. The Virtual Subnet Selection sub-
option of the relay-agent-information option is used by the relay
agent to tell the DHCP server important information about the VPN
(called the Virtual Subnet Selection information, or VSS) for every
DHCP request it passes on to the DHCP server, and is also used to
properly forward any DHCP reply that the DHCP server sends back to
the relay agent.

NOTE:   The mail server at ietf.org 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
