how can we configure two DHCP on a network?
can anyone tell me step by step with explaination?
It's a recipe for disaster, putting two DHCP servers on the same Layer 2 segment.
What I would do is create a second network (VLAN, separate NIC and switch, etc) for the PXE boot environment. Otherwise, you're just setting yourself up to have weird issues.
Alternatively, you could have the Linux server serve all DHCP requests, disable the DHCP server on the Linksys router, and put the router's IP as the default gateway for the network. It's perfectly acceptable to divorce DHCP from router functions. We do it in every one of our networks, and we have a few hundred of them (serving 11M users).
