[j-nsp] JUNOS BootP-relay Behaviour

[alain.briant at bt.com]

When I configure DHCP relay like this on an EX switch:
 
"set forwarding-options helpers bootp interface XX server @IPDHCPserver"
 
The outgoing relayed paquets are received on the DHCP server with a
source address
of the outgoing interface of the EX switch (the Net IP.B address)
 
                                             __________
                        _______             {          }
              Net IP.A |       | Net IP.B  {            }
DHCP client |----------| EX SW |----------{      NET     }--| DHCP
server
                       |_______|           {            }
                                            {__________}
 
 
 
On a C router and other brands the behaviour is different and the
address used 
is the one from the incoming interface (the Net IP.A address)
 
Does someone know if the behaviour of the JUNOS relay can be changed to
use the
incomming interface address?
 
Thanks for your help
