Suppose an IP data gram arrives at a host H with a TTL value of 0 What would H do with the datagram? (There may be multiple answers) Always discard the datagram with a TTL exceeded message to the source If the destination IP of the datagram is H, process the datagram by sending it to transport layer If the destination IP of the datagram is not H, then H must be a router, so discard the datagram with an ICMP message to the source Discard the datagram silently (no ICMP messages)
