Shared Network Question

[Clayton Keller]

I have a setup in which a DHCP request is coming in from a Relay Agent 
IP address of 192.168.121.2, however, I'd like to assign it an address 
from a 10.10.45.0 subnet.

My understanding was I could use a shared-network to handle this type of 
situation. We are also looking at using some Option 82 info as well.

Here is my configuration for the shared network:

shared-network Lab
{
         subnet 192.168.121.0 netmask 255.255.255.128
         {
         }

         class "Test"
         {
                 match if option agent.circuit-id = "XXXX";
         }

         subnet 10.1.45.0 netmask 255.255.255.0
         {
                 default-lease-time 1800;
                 max-lease-time 3600;
                 option routers 10.1.45.1;
                 option broadcast-address 10.1.45.255;

                 pool
                 {
                         failover peer "failover";
                         deny dynamic bootp clients;
                         allow members of "XXXX";
			range 10.1.45.10 10.1.45.254;
                 }
         }
}

When I have this config loaded on both dhcpd servers, the following 
response is seen from the logs when the discover packet is received.

dhcpd: DHCPDISCOVER from xx:xx:xx:xx:xx:xx via 192.168.121.2: peer holds 
all free leases

I'm not sure if I'm not setting this up properly, or if this is a viable 
option to the setup we are working with regarding the incoming traffic.
