Parameters

interface-number: Specifies the L2VE interface number. The value range for this argument is 1 to 8192.

interface-number.subnumber: Specifies the L2VE subinterface number. The interface-number argument specifies the interface number, in the range of 1 to 8192. The subnumber argument specifies the subinterface number, in the range of 1 to 8192.

Usage guidelines

A VE-L2VPN interface (an L2VE interface) or an L2VE subinterface terminates MPLS L2VPN packets. The L2VE interface performs the following operations:

·     Removes the MPLS label from an MPLS L2VPN packet.

·     Sends the original Layer 2 packet to an L3VE interface or L3VE subinterface that has the same interface number as the L2VE interface.

An L2VE subinterface sends original Layer 2 packets only to the L3VE interface that has the same interface number as the L2VE subinterface.

If an L2VE subinterface receives packets that carry VLAN tags, you must configure the L2VE subinterface to terminate the VLAN tags. For more information about VLAN termination, see Layer 2—LAN Switching Configuration Guide.

Deleting an L2VE interface also deletes all subinterfaces on the interface.

Before you create an L2VE subinterface, the main L2VE interface of the subinterface must already exist.

The VPLS access to L3VPN or IP backbone model does not support creating L2VE subinterfaces.

Examples

# Create L2VE interface VE-L2VPN 100, and enter L2VE interface view.

<Sysname> system-view

Syntax

Default

No L3VE interfaces or L3VE subinterfaces exist.

Parameters

interface-number: Specifies the L3VE interface number. The value range for this argument is 1 to 8192.

interface-number.subnumber: Specifies the L3VE subinterface number. The interface-number argument specifies an interface by its number in the range of 1 to 8192. The subnumber argument specifies a subinterface by its number in the range of 1 to 8192.

Usage guidelines

A VE-L3VPN interface (an L3VE interface) provides access to an MPLS L3VPN or IP backbone for packets. The L3VE interface forwards packets received from the backbone to an L2VE interface that has the same interface number as the L3VE interface.

If packets entering an MPLS L3VPN or IP backbone carry VLAN tags, you must create an L3VE subinterface on the L3VE interface to terminate the VLAN tags. For more information about VLAN termination, see Layer 2—LAN Switching Configuration Guide.

Deleting an L3VE interface also deletes all subinterfaces on the interface.

Before you create an L3VE subinterface, the main L3VE interface of the subinterface must already exist.

Examples

# Create L3VE interface VE-L3VPN 100, and enter L3VE interface view.

<Sysname> system-view

[Sysname] interface ve-l3vpn 100
