enable icmp useredirects

enable icmp useredirects
Description
Enables 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
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 originating router. If ICMP useredirects is enabled, the switch will add a route to the destination
network using the third router as the next hop and start sending the packets to the third router.
Example
The following command enables the modification of route table information:
enable icmp useredirects
