Hi @Steve
Two DHCP servers in a failover relationship synchronize the IP address lease information on a continual basis there by keeping their respective databases up-to-date with client information and in sync with each other.
As I understand, EVEN not manually replicate RESERVATION, the address leases folder is synced with each other. If server A goes down, printer still get the same IP from B, I think no need to manually configure reserve.
If the scope lease time is set to an infinite lease time, the reserved client's lease is also shown as infinite.
Best regards
Karlie
