Separates VLANs with the same IP-Range

I'm not sure how option 82 remote-id relates to the below, but you could cause both relays to allocate from the same ip range by setting up a shared network like this:

shared-network SomeNetwork {
     subnet 192.168.0.0 netmask 255.255.255.0 {
          range 192.168.0.100 192.16.0.150;
     }
     subnet 10.0.3.0 netmask 255.255.255.0 {
          # This will link the 10.0.3.0/24 subnet to the 192.168.0.0/24 subnet for address allocation purposes.
          # any relayed DHCP traffic from source 10.0.3.55 or 10.0.3.70 will cause the DHCP server to allocate 
          # an address from 192.168.0.0/24
     }
}
