Hi,

I have two general questions about the dhcpd and its
implementation/usage.

Is there a way to set up two or more dhcpds in one network? They
should share their configuration and (if necessary) the lease-
db. What I want is redundancy of the dhcp-service...

The other thing I don't know how to implement: Can I configure
the dhcpds for unicast?

Heres my setup:

10.1.1.0/24                 10.1.3.0/24
.--------.  .-.         .-.  .--------.
!Subnet 1!--!R!---. .---!R!--!Subnet 3!        Router supports
'--------'  '-'   ! !   '-'  '--------'        BOOTP/DHCP-Relay
                .-----.                        (RFC 1542)
                !DHCPd!
10.1.2.0/24     '-----'
.--------.  .-.   ! !
!Subnet 2!--!R!---' '--...
'--------'  '-'

The hosts in the subnets sends a dhcp-discover as broadcast.
The router catch this broadcast and transform it to a
unicast-request to the (configured) dhcp-server. Additionaly,
the router uses the field "giaddr" for "remembering" the origin
host who sends the dhcp-discover. The DHCPd should identify the
subnet and answer with an ip-adress out of this range.

Any ideas?


Thanks a lot and best regards,
Peter Janze
