Odp: Need some helps

I have another problem. I,m usung Caldera3 and tried do define Vlans. At first sight all is OK, but using iptraf I see that packets are flowing not only by virtual interfaces (eth1.11, eth1.12). A part of packets (about 1/3) flows by physical interface (eth1) whereas there should be no flows.
Where is problem, where I do mistake? Any ideas?

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!
