I have an ethernet address with a primary address in the 192.168.2.0/24
subnet and a secondary address in the 192.168.3.0/24 subnet.
The Windows 2000 DHCP server has a scope for the 192.168.3.0 subnet, but the
DHCP server itself has an address in the 192.168.2.0 subnet.
I can ping the DHCP server from the secondary address on the router.
I tried using the smart-relay command and debug showed that the router is
indeed forwarding the DHCP request to the DHCP server with a giaddr of
192.168.3.1. However, the DHCP server is returning an answer which the
router says has an invalid XID not_for_us.
When I change the ip address of the DHCP server to 192.168.3.2, it works
fine.
What do I need to do to get the secondary address to work with DHCP?
interface e0
ip address 192.168.2.1 255.255.255.0
ip address 192.168.3.1 255.255.255.0 sec
ip helper-address 192.168.2.102
!
ip dhcp smart-relay
