Enabling ICMP Redirect Messages

You can enable and disable IPv4 ICMP redirect messages globally or on individual Virtual Ethernet (VE) interfaces but not on individual physical interfaces.

By default, IP ICMP redirect globally is disabled and a RUCKUS Layer 3 device does not send an ICMP redirect message to the source of a misdirected packet, but it does forward the packet to the appropriate router. To enable ICMP redirect messages globally, enter the following commands.

Enter global configuration mode.
```
device# configure terminal
```

To enable ICMP redirect messages choose one of the following options:
- Enable ICMP redirect messages globally, go to Step 3.
- Enable ICMP redirect messages on a specific interface, go to Step 4.

Enable ICMP redirect messages globally.
```
device(config)# ip icmp redirect
```
ICMP redirect messages are enabled globally on all interfaces.

To enable ICMP redirect messages on a specific virtual interface, enter the following command at the configuration level for the virtual interface.
```
device(config-vlan-10)# interface ve 10
device(config-vif-10)# ip icmp redirect
```
You can enable ICMP redirect messages on a specific virtual interface, but not on a physical interface.
