Windows 7 decide which route to take if THE PC Has 4 connection (4 X 1 Gig) available to internet

Hi Network experts


realy i need you to figure out the below

1)how windows 7 decide which route to take if  THE PC Has 4 connection (add on 4 X 1 Gig)  available to internet , the route print on windows machine shows the 4 

connection with same metric (metric 10) , the adapter order is as follows 


2)what about the less subnet id if each interface has less subnet id than other



3)the built in interface (gig 0) why have metric of 286 not 10 like others


thank you all 




Hello.As far as I remember,


As far as I remember, Windows uses ANY of the routes with equal metric.

I'm not sure if there is publicly available algorithm, but I believe it may switch from one interface to another if experience packet loss on the current.

So, the conclusion is: the outgoing interface is not predictable.

If you want any kind of reliability you would better to create port-channel and use FHRP on your routers.

Hi Vasili i can't since each

Hi Vasili


i can't since each NIC in different VLAN , thus different subnet




Hello.Why don't you just


Why don't you just route traffic between the VLANs on any router (L3 switch)?

Why do you need 4 NICs for different VLANs?

Even if you need four different VLANs, you may have 4 default gateways, but all of them should heave a consistent view on your network (i.e. any must be able to route traffic to the correct destination).
