Hello ALL! 

Historically our customer has got network where 2 DHCP servers are up and 
running for redundancy purpose. DHCPD config file is common for both servers. 
No issues if we boot down the wire WinPE, any Linux. We observe issue when gPXE 
is booted.
When gPXE requests IP address both DHCP servers send responces. The concequence 
of such behaviour is that gPXE lost network settings. We have localized problem 
to the following small scenario:

1. boot to gPXE 1.0.1 on host A and enter to the interactive mode (Ctrl-B).
2. from another host B start pinging IP address which will be assigned to the 
host A 
3. execute on Host A gPXE command: dhcp net0
4. ping from host B are successful. 
 ...waiting a little bit about 5-7 secs ....
Host A is not pingable.  

If we stop one of DHCP server such issue is eliminated. 

Question: is it a bug of gPXE? _or_ Is it a feature and our customer breaks 
some RFCs?

Thanks,  Oleg.
