I understand, but the question is what if they dont? Or let me rephrase the question. What do standard implementations do if they send a regular IP packet (no DF bit set) and receive an ICMP dest unreachable - Fragmentation reqd message back? Do they fragment this packet and then send it out again with the MTU reported in the ICMP error message, or is the ICMP error message silently ignored?

All IPv4 routers are supposed to support fragmentation per RFC 1812 (Router Requirements), section 4.2.2.7.
