I am a little confused by your scenario. Are you saying that all of your
clients have reserved IP's? If not, I could see the following scenario
occurring:
Client A has reservation for 199.222.222.55 from Server 1
Client B requests IP address from Server 2
Server 2; not having a reservation for 199.222.222.55, assigns it to Client
B
Client B is unable to participate on the IP network because it detects an
IP Conflict.
Perhaps I am missing something? The scenario I understood from John Chu was
the following:
Server 1 has scope 199.222.221.50 to 224 (leaving IP's available for
servers, routers, etc)
Server 1 has scope 199.222.222.50 to 100 (all for static reservations)
Server 2 has scope 199.222.222.50 to 100 (all for static reservations -
redundancy)
Server 2 has scope 199.222.223.50 to 224 (leaving IP's available for
servers, routers, etc)
In order to make your DHCP servers has redundant as possible, you might want
to run DHCP backup, and then use a utility like DHCPEXIM to export/import
the database.

That is exactly what I do here.
This is an example, maybe it will help:
Server 1
199.222.222.50 to 199.222.222.100 reserve 199.222.222.50 to
199.222.222.75
Server 2
199.222.222.50 to 199.222.222.100 reserve 199.222.222.76 to
199.222.222.100
This gives you redundancy, if one of your servers goes down, you just open
up the scope on the other server.
For static ip's you can use 199.222.222.10 through 199.222.222.49; these are
not in the DHCP servers so you don't have to worry.

I think what you may want to do for redundancy since you have two dhcp
servers is that overlaps a section of the address on both servers and make
the static reservations on both. Make sure this section is use for static
only and the address assigned has to be the same on both servers otherwise
you'll run into duplicate IP address issue.

Yes - but if you do as you state in your original question and use IP
addresses OUTSIDE of either scope a reservation would not be required
because those servers would not know of that IP address to dynamically
assign it to anyone anyway.

Now if I use IP address that belongs to either of the scopes then couldn't
the other DHCP server assign an IP address from its pool when the DHCP
request goes out.
Thanks

Why would you add a reservation for an IP outside of either of the scopes?
If the address is outside of the scope, it will never be assigned by either
of the servers.

I have two DHCP servers running mutually exclusive scope of IP addresses.
If I want to add reservations for IP (that do not belong to either scope)
do I need to add those reservation to both servers OR just one server?
Thanks
