Hello, I have some questions regarding how to bridge VLANs and LAN, I have the following scenarios and configuration, but it dos not seem to work, please shed some light on it. Thanks! I have a Linux box which has 2 GNIC (Eth0 and Eth1) and one ATM card 1.) Scenario I Packets<------->Eth0<--->Eth1.x(VLANs)<--->Internet #vconfig add eth1 1 #brctl addbr br0 #brctl addif br0 eth0 #brctl addif br0 eth1.1 #ifconfig br0 up 2. Scenario II Host 1(10.10.10.x)--->Eth0<--------->Eth1<---->Host 2 (11.11.11.X) #brctl addbr br0 #brctl addif br0 eth0 #brctl addif br0 eth1 #ifconfig br0 up I can ping if and only if Host 1 and Host 2 are in the same domain, say 10.10.10.X. I believe that bridge should be able to bridge traffics between different network domains, but how? Any help is much appreciated!
