Consider the arrangement of learning bridges in Figure 2. Assuming all the tables are initially empty, answer the following questions. There are no ACKs. All of the events below happen sequentially.
(a) Suppose E sends to F. Which bridges learn where E is? Does As interface see the packet?
(b) Suppose K sends to E. Which bridges learn where K is? Does As interface see the packet?
(c) Suppose A sends to K. Which bridges learn where A is? Does Ds interface see the packet?
(d) Suppose E sends to F again. Is any new information gained? Does As interface see the packet this time?
ALSO Do the problem again, this time the hosts ACK the receipt of packets.
