If I make a pair of rdd interfaces (rdd0, rdd1), and give an IP to rdd1, and then bridge eth0 to rdd0, then my bridge works as normal, but the packets end up on rdd1, which has an IP. For me, this means I can bridge with my custom bridge, and route at the same time. And, I can use standard packet sockets in user space and net_device API in the kernel. This last part is of critical importance to me as my kernel module is closed source. The rdd can also be useful for prototyping my application on a machine with few real network interfaces. I am not sure anyone else needs such a thing, but it definately solves one of my problems :) Ben >j > > >_______________________________________________ >Vlan mailing list >Vlan@xxxxxxxxxxxxxxx >http://www.lanforge.com/mailman/listinfo/vlan > > > -- Ben Greear <greearb@xxxxxxxxxxxxxxx> Candela Technologies Inc http://www.candelatech.com
