Configuring CoS Routing Instances (NSM Procedure)

You can apply a custom MPLS EXP classifier to the routing instance with VPN routing and forwarding (VRF) table labels enabled using this option. The default MPLS EXP classifier or one that is previously defined can be applied for routing instance.

To configure Class-of-Service routing instances in NSM:

  1. In the NSM navigation tree, select Device Manager > Devices.
  2. Click the Device Tree tab, and then double-click the device to select it.
  3. Click the Configuration tab. In the configuration tree, expand Class of Service.
  4. Select Routing Instances.
  5. Add or modify settings as specified in Table 1.
  6. Click one:
    • OK—Saves the changes.
    • Cancel—Cancels the modifications.
