If you observe ICMP error messages, describe how they are used for Path MTU Discovery.
What will be an ideal response?
An ICMP error message is generated by PC3, this is because when using Path MTU
Discovery, PC3 has an MTU value of 500 bytes, therefore it has to fragment the packet sent by PC1 which is 1500 bytes in size, but this is a TCP packet with its DF bit set, PC3 has no choice but to send back an ICMP error. This ICMP error message also includes the MTU size of the interface that generates the error. When the ICMP error message arrives at PC1, the TCP protocol will automatically decrease the segment size to the size advertised by PC3 so that new data generated by the TCP will not exceed the MTU size of PC3.
