DHCP on a per-vlan basis?

Like this, do you mean?

! ip dhcp pool net-1 network 192.168.1.0 255.255.255.0 default-router 192.168.1.254 ! ip dhcp pool net-2 network 192.168.2.0 255.255.255.0 default-router 192.168.2.254 ! interface vlan1 ip address 192.168.1.254 ! interface vlan2 ip address 192.168.2.254 !

Aha! That makes sense. I wish the cisco docs explained it a little simpler, but that does make perfect sense.

In order for a router to hand out DHCP for a network, it obviously needs an IP address in that same network to receive the broadcast, and the router would match the network the broadcast was received on with the dhcp pool's "network" statement.

Thanks for making the totally obvious appear before my eyes. Thanks a mil' mate.:)

Not clear. Can you elaborate what you mean?

if i understand you correctly,...

yes

router doesn't forward broadcast by default unless you allow them to. That is why ip helper-address is needed to be configured on the interface. If dhcp request was received by the router and the router has a pool it can give, then it reply to the client without needing to relay. It will know which pool of address to give based on gi add.
