How do DHCP and bootp handle multiple subnets?

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.

How many DHCP servers can you have on any one subnet or flat network?

two DHCP servers
You can run two DHCP servers on the subnet and let one distribute addresses .

When BOOTP can be better than DHCP?

BOOTP stands for Bootstrap protocol. DHCP stands for Dynamic Host Configuration Protocol. BOOTP has no support for temporary IP Addressing. DHCP Server support for temporary IP Addressing but for limited period of time.

What method does a DHCP client use to locate a DHCP server?

The client discovers a DHCP server by broadcasting a discover message to the limited broadcast address (255.255. 255.255) on the local subnet. If a router is present and configured to behave as a BOOTP relay agent, the request is passed to other DHCP servers on different subnets.

How to scope DHCP for two different subnets?

Assign its IP to be in the .6 subnet and make sure the DHCP service is binding to that interface. You CAN NOT get away with just assigning a .6 subnet IP to the SAME NIC, I tried. It must be a different NIC (probably because of the MAC address). If your Windows server is a VM you are golden with 0 downtime probably.

Can a DHCP server refuse to serve a subnet?

If your server is 192.168.5.10/24 but you want it to serve DHCP to 192.168.6.0/24 subnet, windows DHCP server will refuse to serve to the .6 subnet. It doesn’t know they are right on top of eachother. So add another NIC.

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 you use DHCP on more than one network segment?

Support DHCP clients on a single physical network segment (such as a single Ethernet LAN segment) where multiple logical IP networks are used. But the above really isn’t the best design. You should consider alternatives.
