Hi everyone, i'm trying to do a redundant bridges, with 2 root bridges and 4 non-root bridges. So normaly 2 non-root will connect to a single root, but if one root is down, his two non-root will connect to the other root, and this works fine with the parent command in the non-roots, now this is the question: Is it posible that when the root that was down then goes up his two non-roots get back to him? a kind of fallback? If someone can give an advice or a link of configuration i'll appreciate so much. Thanks in advance.
