Can one DHCP server service multiple IPv4 subnets?
A subnet declaration is required for every network your DHCP server is serving. Multiple subnets require multiple subnet declarations. If the DHCP server does not have a network interface in a range of a subnet declaration, the DHCP server does not serve that network.
How do DHCP and BOOTP handle multiple subnets?
First of all, you can set up a seperate server on each subnet. Secondly, a feature of some routers known as “BOOTP forwarding” to forward DHCP or BOOTP requests to a server on another subnet and to forward the replies back to the client.
What is the most significant change of DHCP over BOOTP?
DHCP Operation: — A significant difference between a DHCP configuration and a Bootp configuration is that an IP address assignment from a DHCP server is automatic, requiring no configuration of the DHCP server. Using that automatic feature, though, the address is temporarily leased.
Can I have 2 DHCP servers on the same network?
Not really, unfortunately. On the same subnet, you absolutely cannot run two DHCP servers that assign addresses from the same range. However, on the same subnet, you can have two DHCP servers that assign addresses from different ranges. You can run two DHCP servers on the subnet and let one distribute addresses .
How to setup DHCP server with multiple network interfaces?
The dhcp server should serve a different subnet on the interfaces eth1, eth2, eth3. Each subnet has its own vSwitch (vSphere) and the dhcp server is connected to each vSwitch. The network interface setup looks like this:
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.
How to substitute 2 for 3 in DHCP server?
Substitute 2 for 3 where desired. After this, configure each VLAN with an IP helper address of the DHCP server. IP helper tells traffic where to go to get a DHCP lease, but tags the traffic for that specified VLAN, and makes the request appear to come from the VLAN IP address.
Can a DHCP server issue from two separate scopes?
As others have mentioned, to have a Windows DHCP server issue DHCP leases from two separate /24 scopes, you would want to implement VLANs. I don’t recommend using a superscope unless absolutely necessary. It just gets ugly. For VLANning, you would need a managed switch that handles VLAN tagging.
