This is regarding my problem when using Spanning Tree Protocol. I found out that we can use the following command to manually select the root bridge: brctl setbridgeprio br0 <prio> where the lower <prio> is, the higher the priority. But I have a problem. When I put in this command in the Init Script, it does not seem to affect the value of the prio after the router boots up. So I suspect that the Init Script was executed before the default bridge priority was set. Is there a way for me to run it once after the default bridge priorty is set after bootup?
