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,
Koen
