Multiple DHCP servers for Different VLAN

[samhopealpha]

Hi all,

Here is my environment:

- There are 3 VLan configured in a single switch (vlan5, vlan100, vlan200)

vlan5 is production environment (10.10.5.x)

vlan100 is the testing environment (10.10.100.x)

vlan200 is the testing environment (10.10.200.x)

- there is already an existing DHCP server in the production network

- a new router will be added into the network, and to be a new DHCP server for testing enviroment

- A trunk connection has been created between the switch and router

How do I ensure that the new router's DHCP would not affact the vlan5(production environment) and successfully provides DHCP service to vlan100 and vlan200?

Thanks

Sam

add ip helper command under the interface vlan that will use the new DCHP server.

I have created 2 DHCP pool on the new router,

seems there is no conflict to the VLAN 5 without the ip helper command...

if a new device plug to the vlan5 switch port, will this new device get the correct DHCP pool from vlan5?

or randomly/wrongly get DHCP pool from vlan100/vlan200 ?

Thanks for the reply
