Usage guidelines
A device sends ICMP destination unreachable packets by following these rules:
• If a packet does not match any specific route and there is no default route in the routing table, the
device sends a Network Unreachable ICMP error packet to the source.
If a packet is destined for the device but the transport layer protocol of the packet is not supported
•
by the device, the device sends a Protocol Unreachable ICMP error packet to the source.
If a UDP packet is destined for the device but the packet's port number does not match the running
•
process, the device sends the source a Port Unreachable ICMP error packet.
If the source uses Strict Source Routing to send packets, but the intermediate device finds that the
•
next hop specified by the source is not directly connected, the device sends the source a Source
Routing Failure ICMP error packet.
If the MTU of the sending interface is smaller than the packet and the packet has a Don't Fragment
•
set, the device sends the source a Fragmentation Needed and Don't Fragment-Set ICMP error
packet.

# Enable sending ICMP destination unreachable packets.
