Problem 4(5+5 pts). Consider the figure below showing an extended L AN connected using bridges B1 and B2 (aka. Fig. 4-33(b) of the textbook): Recap textbook Ch. 4.7.2 and answer the following questions: 1 1. Suppose the hash tables in the two bridges are empty initially. What docs B2's hash table (i.e., what station is on what port) look like after the following sequence of data transmissions: 1) B sends a frame to E. 2) F sends a frame to . 3) A sends a frame to B. 4) G sends a frame to E. 5) D sends a frame to C. 6) C sends a frame to . 2. Suppose the hash tables in the two bridges are empty initially. Which of these data transmissions leads to a broadcast: 1) A sends a frame to C. 2) B sends a frame to E. 3) C sends a frame to B. 4) G sends a frame to C. 5) E sends a frame to F. 6) D sends a packet to C
