Creating VC Subranges That Include Static ATM Interfaces

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. This example is essentially the reverse of the procedure in Creating Static ATM Interfaces Within VC Subranges.

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

1. Specify a static ATM 1483 subinterface.

   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.

   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.

   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

atm bulk-config

• Use to create a bulk-configured VC range on a static ATM AAL5 interface for use by a dynamic ATM 1483 subinterface.
• For detailed information about how to use this command, see atm bulk-config.
• Example

  host1(config)#atm bulk-config test1 vc-range 0 1 101 600
  vc-range 3 5 201 3200

• Use the no version to remove the specified VC range from the ATM AAL5 interface, to remove the specified subranges from the specified VC range, or to remove all subranges from the specified VC range. The no version also removes any overriding profile assignments for ATM PVCs within the deleted VC range or VC subrange.
• See atm bulk-config.

atm pvc

• Use to configure a PVC on an ATM interface.
• Specify the VCD, the VPI, the VCI, and the encapsulation type. For more information about these parameters, see Creating a Basic Configuration in Configuring ATM .
• You can create a PVC within an existing bulk-configured VC subrange, or a bulk-configured VC subrange that includes the VPI and VCI values of an existing PVC.
• Use the aal0 encapsulation keyword to cause the router to receive raw ATM cells on this circuit and to forward the cells without performing AAL5 packet reassembly.
• Example

  host1(config-subif)#atm pvc 10 100 22 aal0

• Use the no version to remove the specified PVC.
• See atm pvc.

interface atm

• Use to select an ATM interface or ATM 1483 subinterface.
• For information about specifying the ATM interface or subinterface, see interface atm.
• Examples

  host1(config)#interface atm 5/0.1

  host1(config)#interface atm 4/0/2

• Use the no version to remove the interface or subinterface.
• See interface atm.

mpls-relay

• Use to route layer 2 traffic to the specified router.
• For detailed information about using the mpls-relay command, see chapter Configuring Layer 2 Services over MPLS in JUNOSe BGP and MPLS Configuration Guide.
• Example

  host1(config-if)#mpls-relay 10.10.100.2 45

• Use the no version to negate this command.
• See mpls-relay.
