DHCP HA Reservation replication support

Howdy,

Is there any change that 2025 will support replicating DHCP reservations finally within a DHCP HA setup?  We have to rely on powershell scripts today to accomplish this.

Thanks!

    Agreed, DHCP Failover "cluster" without using Failover Cluster Manager but DHCP internal failover (active / passive or active / active (loadbalancing) feature does replicate everything BUT not

    - new or changed DHCP scopes
    - MAC reservations

    in both cases this can be done via Script or MMC (Replicate Scopes)

    I would be thrilled to see this changing.

    Idea: scheduled task doing this work, so you do not have to change much on the service.

    You made me curious! All DHCP HA setups I had in my hands now, since Server 2012, did replicate the reservations to the other side. ( I cannot tell for Server 2008 R2 and before since I never ran DHCP in HA there, but I suspect it is that way since Server 2000 ).
    So what is the exact HA setup you use?
