Usage guidelines
ICMP redirect messages simplify host management and enable hosts to gradually optimize its routing table.
A host that has only one route destined to the default gateway sends all packets to the default gateway. The default gateway sends an ICMP redirect message to inform the host of a correct next hop by following these rules:
The receiving and sending interfaces are the same.
The selected route is not created or modified by any ICMP redirect message.
The selected route is not destined for 0.0.0.0.
There is no source route option in the received packet.
