Example: Configuring ICMP Router Discovery Protocol (NSM Procedure)

You can enable and disable IRDP and configure or view IRDP settings using NSM. When you enable IRDP on an interface, NSM initiates an immediate IRDP advertisement to the network. For information about configuring an interface, see the Network and Security Manager Administration Guide.

To configure IRDP for the trust interface:

1. In the NSM navigation tree, select Device Manager > Devices.
2. Select a security device and then double-click the device on which you want to define forced timeout. The device configuration appears.
3. In the device navigation tree, select Network > Interface.
4. Select a trust interface, and click Edit.
5. In the interface navigation tree, select Protocol and select the IRDP tab.
6. Select the Enable IRDP check box.
7. Click OK to apply the settings.

Table 1 lists the IRDP parameters, default values, and available settings.
