Hello,
I have built several bridges that are connected to a ring via wlan
devices. To avoid the problems mentioned in FAQs i use tap-tunnels over
the wlan links. So my bridge looks like this:
eth0
|
tap0 ---- br0 ----- tap1
When traffic is going from tap0 to tap1 it is almost impossible for eth0
to insert traffic. Is there some priority concerning the traffic on an
interface?
Is there a way to influence this behavior?
These are my settings:
[root at swa root]# brctl show br0
bridge name bridge id STP enabled interfaces
br0 0014.0000cb2610f0 yes eth0
tap0
tap1
[root at swa root]# brctl showstp br0
br0
