DHCP Failover On Windows Server

What is DHCP Failover and How it's Work?

The DHCP failover protocol provides a method for two DHCP servers to communicate with each other. Depending on the configuration, DHCP failover can provide both redundancy and load balancing by sharing one or more pools between two or more DHCP servers. The servers are known as failover peers.After placing two DHCP servers in a failover relationship, each DHCP pool’s addresses are divided between primary and secondary servers

DHCP failover works by replicating IP address leases and settings in one or more DHCP scopes from a primary DHCP server to a failover partner server.

All scope information is shared between the two DHCP servers, including active leases. This enables either DHCP server to assume responsibility for DHCP clients if the other server becomes unavailable.

Figure

Configaration

Now, I active the Scope In ADDS (Admin.local) and also In( IPAM admin.local )

In IPAM Server > Active the Scope (name = Ipam.admin.local)

In >  ADDS > Address lease

Now , I go to Client PC and check which Ip is connected 

Now if I disable the the Ethernet in admin. local,

Now if I check ,,

This is the Address lease of > IPAM server

This is the Process of DHCP Failover.
