Mikrotik DHCP Server doesn't sends any Interim Update towards Radius Server- as a workaround we are trying "Session-Timeout" value sent by Radius, which is actually working as a lease-expiry timeout. But once the lease expires ( halfway of Expiry-Time ), Radius is simply renewing the lease but no Accounting details are sent. But if we clear the lease manually, we get the Accounting Data like "Input-octets" , "output-octets" etc from DHCP Server.
My question is - is there any way to clear the lease manually when it reaches its expiry? ( halfway of lease-expiry time )

Thanks
