IP Unicast Commands

disable icmp useredirects

disable icmp useredirects
Description
Disables the modification of route table information when an ICMP redirect message is received.
Syntax Description
This command has no arguments or variables.
Default
Disabled.
Usage Guidelines
This option only applies to the switch when the switch is not in routing mode.
If the switch has a route to a destination network, the switch will use that router as the gateway to
forward the packets to. If that router knows about a better route to the destination, and the next hop is
in the same subnet as the originating router, the second router will send an ICMP redirect message to
the first router. If ICMP useredirects is disabled, the switch will disregard these messages, and continue
to send the packets to the second router.
Example
The following command disables the changing of routing table information:
disable icmp useredirects
