6.5.2 Example for Disabling the Sending of ICMP Host Unreachable
Packets
This section provides a configuration example of disabling the sending of ICMP host
unreachable packets.
Networking Requirements
As shown in
and Switch C are required and these devices are connected through their GigabitEthernet
interfaces.

Data Preparation
To complete the configuration, you need the following data:
Issue 01 (2012-03-15)
interface vlanif 10
ip address 2.2.2.2 255.255.255.0
#
interface GigabitEthernet1/0/0
port hybrid tagged vlan 10
#
return
Figure 6-2, to limit the sending of ICMP redirection packets, Switch A, Switch B,
GE1/0/2
VLANIF11
2.2.2.2/24
Assign IP addresses to interfaces on Switches.
Configure static routes to indirectly connected devices.
Enable the sending of ICMP host unreachable packets in the interface view.
NOTE
By default, the sending of ICMP host unreachable packets is enabled on the interface view. If the
configuration is not changed, you can skip this configuration.
