DHCP Relay agent

[lkatsaros]

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.

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)

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.
