This is a question w.r.t server behavior in the DHCP standard. I've read the RFC and it's still not clear to me.

Situation is this:

There are two DHCP servers on a network. My client initially get IP address from server A. At some stage, server A goes down. My poor client is sending REQUEST in RENEW and then REBIND state, with no response whatsoever.

My questions is: in this situation, should server B response to the REQUEST in REBIND state, e.g. DHCPNAK?

Thanks,
