Hi all,
        I have a Linux box with 3 interfaces eth0,eth1 and eth2.
        Could anyone please let me know whether the following configuration
would be valid :

*#brctl addbr br1
#brctl addif br1 eth1
#ifconfig br1 up
# brctl show
bridge name     bridge id               STP enabled     interfaces
br1             8000.001000000007       no              eth1


# brctl addbr br0
# brctl addif br0 eth0
# ifconfig br0 up
# vconfig add br0 5
# brctl addif br1 br0.5

# brctl show
bridge name     bridge id               STP enabled     interfaces
br1             8000.001000000006       no                       br0.5

eth1
br0             8000.001000000006       no

#
# ifconfig br0.5 up*

Thanks.

A bridge can not be added to a bridge.

I think you're looking for more vlan capability than the current Linux 
bridging code has. I posted a patch a few years back to add vlan aware 
bridging to the kernel - it would be great if someone updated it to the 
current kernel. Here's a reference:
