I'm trying to find evidence that carp can work with dhcpd. All of the

The ISC dhcpd has it's own failover method, which might be what I should
use, but it would be nice if it it could work with carp.
It's not clear to me how carp disables the inactive interface on the
secondary machine. If it can still respond to layer 2 requests, this might
not work.
I realize that a simple test could be done to see if dhcp would still
listen and send ethernet frames on the carpX device on both sides, but it
would take some time to get to that point, and I haven't bought the second
carp device yet.
I'm using a static setup inside my dhcpd.conf (hardware ethernet and
fixed-address) so leases are not an issue (although dhcpd seems to be
able to deal with a lost lease file).
If you distribute static IP configurations only: I wouldn't bother
with failover. Let both of the DHCP servers make their offers. The client
will choose one and ignore the other.
Take care
