Disabling and Reenabling ICMP Redirect Messages
An ICMP redirect is a message sent by the router to alert a host that it should be
using a different path to route data.
In some cases, you do not want an interface to send out redirects. For example, in
an ATM or frame relay network, two stations on the same network may not be
directly connected if the network is not fully meshed. Thus, in this case, you
would disable redirects on this interface.
By default, IP sends ICMP redirect messages. You can use the BCC or Site
Manager to disable and reenable this feature on an IP interface as required.
Using the BCC
By default, IP sends ICMP redirect messages. To disable or reenable ICMP
redirect messages, go to an IP interface prompt (for example,
box; eth 2/2;
ip/2.2.2.2/255.255.0.0
) and enter:
redirects
<state>
state
is one of the following:
enabled
(default)
disabled
For example, the following command turns off ICMP redirect messages on IP
interface 2.2.2.2:
ip/2.2.2.2/255.255.0.0#
redirects disabled
ip/2.2.2.2/255.255.0.0#
