Description

Smart Proxy should support multiple dhcp records for the same ip address to support bonded interfaces. Cobbler already supports this.

It should be possible to deploy two dhcp reservations for a single nic.
The ipaddress and hostnames should be the same, the macs and names should differ.

Conflict detection should not mark these records as a conflict.

There's a chance that it might be possible with ISC dhcpd when 'option dhcp-client-identifier' is used to explicitly set client ids, but it needs to be checked (it also doesn't apply to most setups, as not all eherhnet switches support forwarding of custom client ids). I don't think this is possible with MS dhcp at all (but also needs to be verified).

Dimitri, what do you want to gain from the client id? I believe (and tests indicate that as well and cobbler does it in a similar way) that it's enough to deploy to reservations and make the checking for duplicates/conflicts more intelligent. I'd have foreman send a white list of mac addresses and filter the duplicates by them. Should work, I guess.
