Given an Ethernet frame, what fields does a host need to examine to determine whether the frame contains an ICMP message?
What will be an ideal response?
ICMP uses IP to transport each error message: when a router has an ICMP message to send, it
creates an IP datagram and encapsulates the ICMP message in the datagram. The ICMP message is
placed in the payload area of the IP datagram, and then datagram is encapsulated in a frame. So an
Ethernet frame should be checked for IP and then within IP we should check the field type to
determine if it contains an ICMP message.
