As far as I am aware, with a normal dhcp lease renewal this is all handled 
transparently. With Debian, even if the dhcp server is missing at that point 
(!), the client will just continue using the same IP configuration it had already.

Network Manager, on the other hand, insists on dropping the link and creating it
