You observe that the following packets are transmitted from different egress ports of an 8-port
switch. You do not have access to the ingress ports. That is, you can only see what comes out of
the switch, not what goes into it. - 70,60 denotes a packet with DA=70 and SA=60. - No address
migration. No timer expiration. (a). Show the content of the forwarding table after packet 4. (b). If
the next packet (packet 5) has DA=80 and SA=60, predict which egress port(s) will see this
packet.
