Configuring Static ATM Interfaces Within VC Subranges

The following topics describe how to configure static ATM interfaces within VC subranges:

Creating a Static ATM Interface Within an Existing Bulk-Configured VC Subrange

You can configure a static ATM interface with an ATM PVC whose VPI and VCI addresses fall within an existing bulk-configured VC subrange.

To create a static ATM interface within a VC subrange:

  1. Create a bulk-configured VC range that includes one or more VC subranges.
    host1(config)#interface atm 0/0 host1(config-if)#atm bulk-config test vc-range 1 3 32 1031
  2. Specify a static ATM 1483 subinterface. For more information, see Creating a Basic Configuration in Configuring ATM.
    host1(config-if)#interface atm 0/0.2100
  3. Configure an ATM PVC with VPI and VCI values that fall within the bulk-configured VC subrange. In this example, the VPI value (2) is within the VPI range 1–3, and the VCI value (100) is within the VCI range 32–1031. For more information, see Creating a Basic Configuration in Configuring ATM.
    host1(config-subif)#atm pvc 2100 2 100 aal0
  4. Configure the static ATM interface. For example, the mpls-relay command creates a ATM layer 2 services over MPLS tunnel on the circuit. For detailed information about using the mpls-relay command, see Configuring Layer 2 Services over MPLS in JunosE BGP and MPLS Configuration Guide.
    host1(config-subif)#mpls-relay 192.168.0.1 2100

Creating a Bulk-Configured VC Subrange that Includes an Existing Static ATM Interface

You can configure a bulk-configured VC subrange that includes the VPI and VCI addresses belonging to an existing ATM PVC on a static ATM interface.

To create a VC subrange that includes a static ATM interface:

  1. Specify a static ATM 1483 subinterface. For more information, see Creating a Basic Configuration in Configuring ATM.
    host1(config-if)#interface atm 3/1.201
  2. Configure an ATM PVC on the static ATM 1483 subinterface. In this example, the VPI value is 1 and the VCI value is 101. For more information, see Creating a Basic Configuration in Configuring ATM.
    host1(config-subif)#atm pvc 201 1 101 aal0
  3. Configure the static ATM interface. For example, the mpls-relay command creates an ATM layer 2 services over MPLS tunnel on the circuit. For detailed information about using the mpls-relay command, see Configuring Layer 2 Services over MPLS in JunosE BGP and MPLS Configuration Guide.
    host1(config-subif)#mpls-relay 5.1.1.1 201
  4. Create a bulk-configured VC range that includes the VPI and VCI values of the previously configured ATM PVC. In this example, the VPI range (0–2) includes VPI 1, and the VCI range (100–250) includes VCI 101.
    host1(config)#interface atm 3/1 host1(config-if)#atm bulk-config test2 vc-range 0 2 100 250
