Hi Thomas,

The primary challenge to failover performance, is that it is a synchronous
protocol.  Servers are
supposed to wait until their peers acknowledge that a least update has been
received prior to sending the corresponding response (i.e. DHCPACK)to the

---> I have doubt about this topic, The dhcp failover protocol support lazy
update right?
server grants the leases for the client and updates the peer server after
client lease acknowledgment, This is how it can operate even if the peer
server is down, please correct if I am wrong
