i only know that happen with ip helper-adress command.but how different vlan getting different scope range from dhcp server

If you're using Windows 2000/2003 as your DHCP server, just create a new scope for those other ranges.

The ip helper-address inserts a GIADDR field into the packets so that the DHCP server knows which scope to give an address from.

Not all DHCP servers can do this.
