Forget reservations, if your DHCP server goes down, your problems will be
more difficult than reserved IP addresses. 

 

Trust me; you just need to make one reservation for each IP. 

 

Now, if your multiple dhcp servers got the same IP range, then you are
replicating your servers with dhcp replication enabled. If this is your
case, you just need to define the reservation one time on the main server,
and the replication program will set the reservation on the other servers.

With multiple dhcp servers - how is redundacy achieved with regards to
reserved addresses?    If reserved addresses are configured on only one
server what happens if that server goes down?

If you have multiple DHCP servers, everyone should have a different IP
range. The reservations on each server consist of IP INSIDE that range, so
you just need make one reservation.

 

The IP duration depends on the stability of your network. If mostly of your
clients are desktops and you have a good margin of remaining IP addresses,
you can make it bigger (20 days in my network), on the other hand, if you
have a few margin of IP addresses and/or have a lot of mobile users, your
lease should be lower (3 days for instance)

How are reserved ip addresses configured on multiple dhcp w2k servers?
Are reserved addresses duplicated on each server?          

What do you recommend for ip address lease duration?
