Configuring Maximum Paths (NSM Procedure)

You can configure a limit for the number of routes installed in a routing table based upon the number of route paths in the table.

To configure a maximum paths limit in NSM:

  1. In the navigation tree, select Device Manager > Devices.
  2. In the Devices list, double-click the device to select it.
  3. Click the Configuration tab.
  4. In the configuration tree, expand Routing Options.
  5. Select Maximum Paths.
  6. Enter the parameters as specified in Table 54.
  7. Click one:
    • OK—To save the changes.
    • Cancel—To cancel the modifications.
    • Apply—To apply the routing option settings.

Note: After you make changes to a device configuration, you must push that updated device configuration to the physical security device for those changes to take effect. You can update multiple devices at one time. See the Updating Devices section in the Network and Security Manager Administration Guide for more information.
