Routing problem with 2 network cards

[Tsuioku]

Hello,

I have some difficulties managing routes for my network cards. I have 2 network cards, one I use for internet, the other for multicast. Apparently, the current behaviour is that Windows chooses the first card he founds for multicast, and that will be the internet one.

So, my cards are configured like this :

. internet :
IP : 192.168.1.66
mask : 255.255.255.0
gateway : 192.168.1.1 (this is my router)
dns : 192.168.1.1

. multicast :
IP : 192.168.0.2
mask : 255.255.255.0
gateway : empty
dns : empty

The "route print" command shows this :

224.0.0.0        240.0.0.0         On-link      192.168.1.66    276
224.0.0.0        240.0.0.0         On-link       192.168.0.2    276

and interface number for internet card is 11 and 17 for the multicast one.

By doing a simple "route delete 224.0.0.0 if 11", I have the behaviour I want. Both internet and multicast. The problem is that this route comes back after reboot.

I tried adding this route :

route add 224.0.0.0 mask 240.0.0.0 192.168.1.66 metric 300 if 11 -p

But after a reboot, the "route print" command shows this :

[COLOR=Red]224.0.0.0        240.0.0.0         On-link      192.168.1.66    276[/COLOR]
224.0.0.0        240.0.0.0     192.168.1.66     192.168.1.66    320
224.0.0.0        240.0.0.0         On-link       192.168.0.2    276

My question is how can I get rid of this route in red that keeps coming back ? And why didn't the added route replace it ?

Thanks for your help !

PS : Every route command has been executed in an elevated command prompt.

It might help to list those routes in the advanced TCP/IP settings window.

I tried to search for what you said, but I can't figure where to do that. I saw I could change the metric for the card, but it changes it for every routes related to the card.

This is mostly for using different subnets but it may work better for what you are trying to do. In the right TCP/ip window you can list the different subnets,IP,default gateway and metric that you want to connect with.

I don't see what to fill in those field that would help my case. Maybe I'm missing something
Anyway, I had the idea of increasing the priority of the multicast card instead of lowering the internet one. And now it works like a charm, yay !
Thanks for your time !

It's easy when you hit the "add" button although it's for adding more than one subnet to a single adaptor so may not work in your case with your two adaptors.

Glad you got it working.
