This option is used for user initiated RENEW request where an attempt 

is made to renew the lease obtained from the orginal DHCP server.

If the server response is not received before the default timeout(RebindTimeT2 - RenewalTimeT1)

the dhcp client will then initiate a REBIND.An user defined timeout can also be

supplied when using this option which will override the default timeout value.
