Does anybody knows why ethernet interfaces stay's up even when i unplug the
ethernet cable?

I have 2 isp connected to a box, with a default route pointing both of them one
using a higer weight to use it as backup conection (using iproute2). Ok, if i
unplug the ethernet cable of eth of isp1 , the ethernet card stays up and nobody
can make any connection. But, if i "really" force the interface shutdown of
provider1 (doing ifdown eth1) the traffic goes instantly trough provider2.

Any idea how can i tear down an interface when i unplug the ethernet cable?

Thanks in advance.
