using bridges B1 and B2. Consider the figure below that shows an extended LAN connected A port 1 B B1 C 3 bridge 4 B2 w N D FL E Initially, the hash table in B1 is empty; the hash table in B2 has two entries: "D on port 1" and "A on port 4". Answer the following questions: 1. Suppose the following data transmissions take place sequentially. Which of them leads to a broadcast? If so, at which bridge(s)? (1) A sends a frame to D (2) F sends a frame to E (3) D sends a frame to C (4) E sends a frame to A (5) B sends a frame to F 2. When the above transmissions are complete, what do B1's hash table and B2's hash table look like? (list the entries in the order they were added)
