Multiple DHCP question

Hi,

Is there a method to provide
- multiple DHCP servers just for redundancy ? (on the same
VLAN/subnet, providing IP's from the same pool)
- a DHCP providing IP's from different pools, depending on the origin
of the requester ? (origin of the requesters switch for instance)

Regards.

You can have multiple DHCP servers on a network. Just give them different
address ranges. A DHCP server can also hand out different address ranges,
according to the interface used.

Hi,

Yes for sure. Just look at

# man dhcpd.conf
(search for failover)

under debian. You need to install the dhcpd3 server of
http://www.isc.org

There you can arrange that.

Actually recent isc dhcpd (>3) have built in fail over capabilities
to provide ha dhcp service (same address ranges).
