Subject: Dynamic assignment of IP address to a relay agent interface

I was reading draft-ietf-dhc-agent-options-07.txt
"DHCP Relay agent Information Option" . Is it possible
for a relay agent with a WAN interface like ATM, with
no IP address set to dynamically assign an IP address
to one of its subinterfaces that are connected to a
LAN (DHCP clients) via a PVC.

Under section 3.1 "Agent circuit ID suboption",
(option 82) the client could receive IP configuration
information from the DHCP server via the relay agent
using an identifier, which in this case could be
either the router sub-interface number or the ATM VC
number. 

Is it also possible for the agent itself, to receive
IP info about itself from the DHCP server. If so will
the agent act as both a client and an agent, when it
acts as a client, does it have to (must) add a
loopback address of itself to be identified by the
DHCP server, and it will also probably have to utilize
option 82 again, to define which sub-interface is
requesting the IP address.

Am I missing something here ?

Thanks
