Problem
1. A router receives an IP packet with source IP address 130.45.3.3 and destination IP address 201.23.4.6. The router cannot find the destination IP address in its routing table. Fill in the fields (as much as you can) for the ICMP message sent.
2. TCP receives a segment with destination port address 234. TCP checks and cannot find an open port for this destination. Fill in the fields for the ICMP message sent.
