And that’s what we have here. That is evident on Switchboard 3. Interface Gig 2 is currently blocked. We do not have user traff ic over that bottom link. And switch three and switch two are both pointing up to switch one. Because switch one is our route bridge, switch three connects to it via interface gig zero one. However, let’s imagine that there was a failure on that link betwe en switch one and switch three. After all, that’s what the spanning tree is built for — to help us recover from something like that. The question we’re going to answer in this video is: how long does it take to recover? Do we immediately start forwarding tra ffic out of gigabit - zero - two? Actually, no. We’re going to remain in that blocking state for 20 seconds. Switchboard three is waiting for bridge protocol data units to be received from switch one. If it does not see any within 20 seconds, it realises somet hing must have happened to the topology, and it’s going to start transitioning its blocking port into a forwarding state. But it does not do it immediately. It next transitions from blocking to listening in the listening state. It is listening for on any o ther interfaces it may have. Right now it only has one other interface, but it’s taking a look at the being advertised around the network and trying to determine which of its ports will become its new route port. And who knows, maybe it’s now the root brid ge, if the root bridge has been destroyed. S o it examines those BPDs for 15 seconds, but we’re still not forwarding user traffic. We then transition from the listening state into the learning state, where we stay for 15 seconds. We are learning Mac address es. We’re starting to populate our Mac address table with traffic seen on our different interfaces. However, we are still unable to forward traffic on gigabit zero two. We haven’t transitioned to the forwarding state yet. But after a total of 50 seconds — 20 seconds spent blocking, 15 seconds spent listening, and an additional 15 seconds spent learning — we finally transition to the forwarding state, and the previously blocked port becomes our new route port. And the previous route port is going to be blocked a gain; that was a total of 50 seconds of delay.
