BID for SW1 can be assumed to be the lowest Bridge ID with lowest mac of any assumptions

Problem 3. LAN operations. Consider the network shown in Figure 2. STP is not running. The LAN is booted up and then user A, connected to SW1, sends a frame to user B, connected to SW4. This is the very first frame on the LAN. User B responds after 1 minute with another frame sent to user A (a) Describe, in detail, the contents of the MAC address tables inside all switches, before the first frame is sent 8.0200 333 3113 otcast: 20 TDRot Cost: 19 82 7780200 4444 Figure 2: The network in Problem 3 (b) Describe, in detail, the contents of the MAC address tables inside all switches, after the response frame is sent.
