mpls l2vpn (System view)

Function

The mpls l2vpn command creates a BGP VPWS instance and displays the MPLS-L2VPN instance view.

The undo mpls l2vpn command deletes a BGP VPWS instance, the MPLS-L2VPN instance view, and all configurations in the view.

By default, no BGP VPWS instance is created.

Format

mpls l2vpn l2vpn-name [ encapsulation { ethernet | vlan | ip-interworking | ip-layer2 } [ control-word | no-control-word ] ]

undo mpls l2vpn l2vpn-name

Parameters

Parameter	Description	Value
l2vpn-name	Specifies an MPLS L2VPN instance name.	The value is a string of 1 to 31 case-sensitive characters, spaces not supported. The string can contain spaces if it is enclosed in double quotation marks (").
encapsulation	Indicates the PW encapsulation type.	-
ethernet	This encapsulation type is used when Ethernet packets do not carry VLAN information.	-
vlan	This encapsulation type is used when Ethernet packets carry VLAN information.	-
ip-interworking	Enables static PW interworking when devices in the interworking are all provided by Huawei.	-
ip-layer2	Enables IP interworking for an LDP PW between a Huawei device and a non-Huawei device. ip-layer2 is required for IP interworking between a Huawei device and a non-Huawei device.	-
control-word	Enables the control word function.	-
no-control-word	Disables the control word function.	-

Usage Guidelines

Usage Scenario

BGP VPWS is a type of L2VPN technology that uses BGP as the signaling protocol to transmit Layer 2 information and VC labels between PEs.

BGP VPWS PWs must be configured in VPN instances. To create a VPN instance, run the mpls l2vpn command.

Prerequisites

MPLS L2VPN has been enabled using the mpls l2vpn command.

Follow-up Procedure

Run the route-distinguisher route-distinguisher command to configure an RD for the VPN instance.

Precautions

The encapsulation type configured using the mpls l2vpn l2vpn-name command must be the same as the encapsulation type used by the two AC interfaces. If the two AC interfaces use different encapsulation types, specify encapsulation-type as ip-interworking when running the mpls l2vpn l2vpn-name command.

Example

# Create a BGP VPWS instance and specify the encapsulation type as Ethernet.
