Release Notes v 1.0 Page 19 of 79

ICMP redirect messages

In software release 07.2.02, ICMP redirect messages are disabled by default, whereas in releases prior to

07.2.02, ICMP redirect messages are enabled by default.

• If ICMP redirect messages were enabled prior to upgrading to release 07.2.02, you will need to re-

enable this feature after upgrading to 07.2.02. To do so, enter the ip icmp redirect command at the

global CONFIG level of the CLI.

• If ICMP redirect messages were disabled prior to upgrading to release 07.2.02, the configuration (no

ip icmp redirect) will be removed from the configuration file after upgrading to 07.2.02, since this

feature is now disabled by default. In this case, ICMP redirect messages will not be sent and no

further action is required.

following example.
