DHCP Relay agent

redifining my dhcp issue. i have windows 2000 DHCP server; and (1)2900 switch segmented with 3 VLANS; each Vlan has a 2500 router. can i use the routers as relay agents using the windows DHCP server.

Re: DHCP Relay agent

If you are using each router for each vlan as default gateway, you can configure each of them as dhcp relay agents. (ip helper-address)

Re: DHCP Relay agent

On the ethernet interfaces of the routers, add:

ip helper-address a.b.c.d

Where a.b.c.d = your DHCP server

Then configure a scope for each of the subnets on your dhcp server, and DHCP requests from those subnets should be fufilled with addresses from the appropriate scopes.
