Hey guys, I'm working with a bridge I set up on Linux 2.6.30.9. I have two boards connected and created a redundant connection between them. Basic set up is: brctl addbr br0 brctl addif br0 vlan1 brctl addif br0 vlan2 brctl stp br0 on Then I bring up the interfaces. Everything seems to be fine. Root bridge is negotiated properly and leaves both interfaces in forwarding mode. The other bridge leaves one port in forwarding and puts the other in blocking mode. However after several seconds a message is printed on my terminal saying that vlan2 lost it's neighbor and goes through the listening, learning and then forwarding states. It then quickly flips back to blocking mode. Is this normal behavior for STP on Linux 2.6.30.9? Or do I have something else going on here? net/bridge/br_stp.c:36 br0: port 2(vlan2) entering blocking state br0: neighbor 8000.3a:1f:34:08:54:56 lost on port 2(vlan2) net/bridge/br_stp.c:36 br0: port 2(vlan2) entering listening state net/bridge/br_stp.c:36 br0: port 2(vlan2) entering learning state br0: topology change detected, sending tcn bpdu net/bridge/br_stp.c:36 br0: port 2(vlan2) entering forwarding state br0: topology change detected, sending tcn bpdu net/bridge/br_stp.c:36 br0: port 2(vlan2) entering blocking state If there's any further information you need, let me know.
