IP HELPER in VLAN

Greetings All

I am getting problem in IP helper commands.I issue commands on Interfaces but did not get IP from DHCP Pool of Router.

Router acting as DHCP---3750---3750--Router as DHCP Client.

Vlan is Up/Up.Alreday done shut /no shut  on All interfaces.

Please check the attached image and guide me.

Re: IP HELPER in VLAN

If I am understanding your drawing you have helper address on vlan 20 and 30. But these vlans are configured to learn their addresses from DHCP. So they would send a request to the broadcast address. They are not able to forward to the helper address till they have an address.

IP HELPER in VLAN

Having looked again at the post I see another significant problem. The router has configured only one DHCP scope as far as I can tell. That scope works for the subnet connecting R1 and R2 on the Ethernet. I do not see any scope configured for vlan 20 or for 30. Each vlan needs its own subnet and its won DHCP scope.

I now see that before posting the question in this form that the original poster also posted the same question in the LAN forum. I suggest that any further discussion be focused on the LAN forum which is where it started.
