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)
We see this too, but why does it matter? DHCP servers are required to
inspect the "giaddr" field in the BOOTP/DHCP header, not the source of
the IP packet.
