"ignore booting" and failover?

[Tina Siegenthaler]

Hi list

I've been having this problem for some time, asked this list already  
once, tried different things - now I was able to nearly solve it, but  
not entirely... so I'm asking again (sorry).

We have this #"!?** Dell server which insist on sending DISCOVERS  
every minute or so on some virtual interface / MAC address ("BMC"),  
but we never found out how to disable that. These DISCOVERS are  
cluttering our dhcp.log, so we'd like to just ignore them and - very  
important - not to log them, but we don't want to give that MAC  
address a valid IP. I added "ignore booting" to the host statement of  
that MAC address, and now at least one of our failover peers indeed  
ignores that client (and also logs nothing). But the other peer still  
logs them with this line:

Oct 24 12:50:25 DHCP-0339 dhcpd: DHCPDISCOVER from 00:14:22:72:6d:cb  
via 130.60.145.1: load balance to peer DHCP-Zool

Hmph. Nearly there, but not entirely. How can I get rid of these, too?  
Ideas?
We used to use some workaround, giving that MAC an IP but with an  
invalid router address so that it couldn't do anything, but this still  
eats up one valid IP which is not ideal...

TIA, Tina
