Sync and Reroot – The Root port then asserts a sync and a reroot signal on all the ports on the bridge. The
signal tells the ports that a new Root port has been assigned and they are to renegotiate their new roles and
states. The other ports on the bridge assert their sync and reroot signals. Information about the old Root port
is discarded from all ports. Designated ports change into discarding states (Figure 7.10).
