Shown below is an internetwork of LANs and bridges. Assume that the cost to connect a bridge to a LAN is the same for all bridges, and the bridge priority value is given by the bridge number. Draw the configuration that would be produced by the spanning tree algorithm. a) Label all of the designated bridges, root ports, and blocked ports. LAN 1 LAN 3 P1 B4 P2 LAN 4 P1 B2 P2 H1 P1 B3 H5 P2 B1 P1 B6 P1 H2 P3 P2 P2 P1 B5 P3 LAN 5 P2 H3 P1 B7 P2 LAN 2 H4 LAN 6 b) What would be the revised configuration if bridge 5 were to fail?
