[Bridge] Does linux support per vlan stp

[Atul Gupta]

Hi,

I want to connect two pc`s on a redundant way with each other. On
those pc`s a 64 bit ubuntu 11.10 is running with kernel version
3.0.0-16-generic.


Setup1:
----------

PC1:
          PC2:


br0
            br1
|
               |
-- eth0.1000  ---------------------------------------------------eth0.1000
|
               |
__eth1.1001 ----------------------------------------------------eth1.1001




When I enable spanning tree on both bridges (brctl stp br0 on). They
both stay sending BPDU packages and no port is disabled. So I get a
loop. For some reason spanning tree is not working.

Setup2:
---------
When I repeat the following test without the VLANs the spanning tree
protocol is working:

br0                                                                          br1
|                                                                              |
-- eth0  -----------------------------------------------------eth0
|                                                                              |
__eth1 ------ -----------------------------------------------eth1







The problems is that in the final solution I only have vlans, so I need Setup1.


Is spanning tree in Linux possible with VLANS?
If so, how do I have to set-up this?

Thanks,

Atul
