[Bridge] STP learning.

[Mikael Jungin]

Hi. I have set up a simple bridge under RedHat-6.2 (yes, I need to use that old Redhat release) which I have updated with the 2.2.20 kernel and the appropriate patch for that version.   I have added two ethernet interfaces to the bridge with these simple steps :   ifconfig eth0 0.0.0.0 ifconfig eth1 0.0.0.0 brctl addbr br0 brctl addif br0 eth0 brctl addif br0 eth1   The bridge works fine, and to my suprise I noticed that I can assign an ip from my DHCP server to the br0 interface using the program "pump" included in Redhat-6.2 (pump -i br0 -h myhostname).  :-)   My only problem is that the br0 interface cannot be configured (with pump) for the first 30-40 seconds or so. I have read/heard that the STP learning sometimes could be the reason for this type of behaviour, since it takes some time to complete.   The solution for me was to add a 60 seconds delay in my start script (which runs at boot time) before assigning the ip to br0. This solution feels like a little unreliable since i only can *assume* that the bridge is up and running after 60 seconds.   So, my question (finally) is this : Is it possible to ask the bridge if the STP learning is completed, so I can get rid of my stupid "60 seconds delay" implementation?    /Mikael
