Hi Experts,

As per the RFC, The DHCP client broadcasts DHCPDISCOVER, DHCPREQUEST and
DHCPINFORM messages, unless the client knows the address of a DHCP server.

Broadcast here means only all network broadcast(255.255.255.255) , or does
it also includes the subnet broadcast.

when Destination Ip(in ip header) is "subnet broadcast", would like to know
the dhcp server behavior with below cases.
1. Destination ip is "subnet broadcast"  and the destination mac is
FF:FF:FF:FF:FF:FF
2. Destination ip is "subnet broadcast" and the destination mac is "unicast
mac"


Regards,
Venkat.
