How DHCP Lease Renewal Works

DHCP Client sends a DHCPREQUEST packetDHCP Client sends a DHCPREQUEST packet11

DHCP Server1 sends a DHCPACK packetDHCP Server1 sends a DHCPACK packet22

If the client fails to renew its lease, after 50% of the lease duration has expired, then the DHCP lease renewal process will begin again after 87.5% of the lease duration has expired

If the client fails to renew its lease, after 50% of the lease duration has expired, then the DHCP lease renewal process will begin again after 87.5% of the lease duration has expired

If the client fails to renew it’s lease, after 87.5% of the lease has expired, then the DHCP lease generation process starts over again with a DHCP client broadcasting a DHCPDISCOVER
