Consider the bridged network as shown in Figure Q4(c). The network consists of FIVE (5) transparent bridges with B1 and B5 being the lowest and highest bridge ID numbers, respectively. A lower bridge ID has priority over that of a higher bridge ID. Similarly, a lower port number has priority over a higher port number. The bridges interconnect FOUR (4) LAN segments S1 to $4, each has a cost associated to it. Construct the spanning tree for the network. Indicate clearly the root bridge (RB), root ports (RP), designated bridges (DB) and designated ports (DP). Indicate also, all disabled ports with an 'X' placed over the connected link.
