■
Uses the router with the highest preference level as the default
gateway (ICMP Router Discovery)
ICMP Router Discovery is useful if you have multiple gateways that
connect a particular subnet to outside networks. By using the
preference setting, you can select which gateway is the preferred
choice.
■
Informs sources that a packet has exceeded its allocated time to exist
within the network (ICMP Time Exceeded)
For more information about ICMP Redirect and ICMP Router Discovery,
