Can you have two DHCP servers with the same scope?
You can have two dhcp servers on the same LAN. You just have to split the scope so ip addresses don’t overlap. If you make sure that Server Conflict Detection is on you should be fine.
Can there be two DHCP servers on the same network?
If you are considering multiple DHCP servers, remember that multiple DHCP servers cannot share any of the same addresses. If you use more than one DHCP server in your network, each server must be configured with their own unique IP address ranges.
How does a DHCP server connect to a subnet?
So you can either configure relay agent (ip helper) on router interfaces connected to your new networks or connect DHCP server to each new subnet directly using additional NICs on DHCP server. Since you mention that there will be routing between all subnets, then you need to configure IP helper address on router interfaces to point to DHCP server.
Is there such a thing as a DHCP relay agent?
This restriction requires all individual subnets have its own DHCP server for DHCP operation, which is practically not feasible in network operators’ networks or corporate computer networks (too many DHCP servers are required in the network!). To address this problem, the concept of a DHCP relay agent has long been adopted [1].
How does DHCP respond to an IP address?
Part of MS standard DHCP offering is that it will respond with an IP address from a scope, based on the interface that receives the DHCP request. So if your DHCP server has two network interfaces lets say A & B, and each interface is in a different subnet.
What are the scopes of a DHCP server?
So if your DHCP server has two network interfaces lets say A & B, and each interface is in a different subnet. DHCP has two scopes, Scope_A and Scope_B, and these match the subnet of the interface then a request from a device received by interface A will get an address from Scope_A, and the same is true from Scope_B.
