ICMP Messages Encapsulation:
ICMP (Internet Control Message Protocol) messages are encapsulated into IP datagrams for transmission over the network. The following types of ICMP messages need to be encapsulated into an IP datagram:
Time Exceeded:
- Time exceeded messages are generated by routers when the Time-to-Live (TTL) value of a packet reaches 0 before reaching its destination.
- These messages need to be encapsulated into an IP datagram to inform the sender that the packet could not reach its destination within the specified TTL.
Multicasting:
- Multicasting involves sending a single message to multiple recipients at the same time.
- ICMP messages related to multicasting, such as Multicast Listener Query and Multicast Listener Report, need to be encapsulated into IP datagrams for transmission over the network.
Echo Reply:
- Echo reply messages are generated in response to an ICMP Echo Request message.
- These messages need to be encapsulated into an IP datagram to be sent back to the original sender as a response to their request.
All of These:
- All types of ICMP messages, including Time exceeded, Multicasting, and Echo reply, need to be encapsulated into IP datagrams for proper transmission and communication over the network.
- The encapsulation ensures that the ICMP messages are properly addressed, routed, and delivered to their intended recipients.
