enable icmp useredirects

enable icmp useredirects


Enables the modification of route table information when an ICMP redirect message is received.

Syntax Description

This command has no arguments or variables.



Usage Guidelines

If the switch has a route to a destination network, the switch uses 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 sends an ICMP redirect message to the originating router. If ICMP useredirects is enabled, the switch adds a route to the destination network using the third router as the next hop and starts sending the packets to the third router.


The following example enables the modification of route table information:
