DHCP on LAN-Segment with secondary IP-Address-Range

Situation:

DHCP-Server (W2K) in VLAN 1 (192.168.168.115/24)

Router between VLAN 1 (192.168.168.1/24) and VLAN 2 (192.168.169.1/24)

Secondary IP-Address-Range in VLAN 2 on Router-Interface (172.0.0.1/24)

Router forwards DHCP-Requests from VLAN 2 to DHCP-Server.

interface Vlan2

ip address 172.0.0.1 255.255.255.0 secondary

ip address 192.168.169.1 255.255.255.0

ip helper-address 192.168.168.115

DHCP-Server receives the packets from Routers Primary address (192.168.169.1) and will give a lease out of that range

Question:

How to configure DHCP-Server / Router to give leases (reservations) out of the secondary range (172.0.0.x) to the clients.

Re: DHCP on LAN-Segment with secondary IP-Address-Range

Unfortunately, there is no way to implement DHCP on the secondary address range.

Hi, I think you should implement a superscope in the DHCP server which includes both subnets within the same Vlan2. Then you should make the coresponding reservations and permitted leasings
