It is a continuous process. It is continuous because the root bridge (or any other bridge) can fail. If root fails, new root needs to be selected, and if anyone else fails, affected part of the tree need to be recomputed again. In order to prevent cycles in the topology, while the tree converges, there is a separate mechanisms to switch ports from non ...

The "election" is really a conceptual idea. Each bridge starts out sending its own bridge ID as the root bridge. If it hears a better ID, it starts sending that one. When all bridges are sending the same root ID, we say the network has "converged", but bridges aren't aware this has happened. The root port is simply the port which ...

xSTP is not a good choice when the link status (up/down) does not reflect actual L2 connectivity. Your diagram shows an L2 connection between BSN-1 and PHX-1 across different ISPs. Since that is very unlikely, you seem to have some L2 tunneling going on there (VPN?). That tunneling possibly hides the actual link status when connectivity is lost, at least for ...

From the scarce information you're giving, a bridge loop seems to be created across that port. The most likely case would be that one of the wireless client has got a simultaneous, wired connection and bridges in between. Diagnostics: Check the WAP log for which client associates at the time the loop is detected. Check your network monitoring for the kind ...
