linux bridging vlans?

[Andraz Sraka]

re

can somebody tell me what am I doing wrong (at this late night hour),
because vlan are not getting bridged at all.

ifconfig eth0 0.0.0.0 up
ifconfig eth1 0.0.0.0 up
brctl addbr br0
brctl addif br0 eth0
brctl addif br0 eth1
ifconfig br0 up
vconfig add br0 X
vconfig add br0 Y

X = vlan-ID (example: 222)
Y = vlan ID (example: 223)

# brctl show
bridge name bridge id STP enabled interfaces
br0 8000.00001a1a4c74 no eth0
eth1



# cat /proc/net/vlan/config
VLAN Dev name | VLAN ID
Name-Type: VLAN_NAME_TYPE_RAW_PLUS_VID_NO_PAD
br0.X | X | br0
br0.Y | Y | br0



dmesg shows that:
br0: port 2(eth1) entering learning state
br0: port 1(eth0) entering learning state
br0: topology change detected, propagating
br0: port 2(eth1) entering forwarding state
br0: topology change detected, propagating
br0: port 1(eth0) entering forwarding state

but still no data is forwarded from one interface to another? Is there
any sysctl stuff, that I need to set up like 'ip_forwarding' when doing
routing? Is there something bridging parameter for forwarding or am I
misconfigured things above?

thanks and regards,
Andraz

I think that the bridge device don't support vlan.
The attached patch could add that support (mind that I haven't compiled
nor tested the patch).
Let me know if it works.

You can't add vlan interface to bridge , bridge connects two or more
physical ethernet interfaces to one logical.

Would be better to first create vlans on eth0/1 and next you can bridge
both vlans.

Something like that:

vconfig add eth0 X
vconfig add eth0 Y
vconfig add eth1 X
vconfig add eth1 Y
brctl addbr br0
brctl addif br0 eth0.X
brctl addif br0 eth1.X

brctl addbr br1
brctl addif br1 eth0.Y
brctl addif br1 eth1.Y
