interface ve-l2vpn
Use interface ve-l2vpn to create an L2VE interface or L2VE subinterface and enter its view, or enter the view of an existing L2VE interface or L2VE subinterface.
Use undo interface ve-l2vpn to delete an L2VE interface or L2VE subinterface.
Syntax
interface ve-l2vpn { interface-number | interface-number.subnumber }
undo interface ve-l2vpn { interface-number | interface-number.subnumber }
Default

Parameters
interface-number: Specifies the L2VE interface number in the range of 1 to 8192.
interface-number.subnumber: Specifies the L2VE subinterface number. The interface-number argument represents the number of an L2VE interface, in the range of 1 to 8192. The subnumber argument represents the number of the subinterface to be created on the L2VE interface. The value range for the subnumber argument is 1 to 4094.
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
[Sysname] interface ve-l2vpn 100
[Sysname-VE-L2VPN100]
# Create L2VE subinterface VE-L2VPN 100.10, and enter L2VE subinterface view.

interface ve-l3vpn
Use interface ve-l3vpn to create an L3VE interface or L3VE subinterface and enter its view, or enter the view of an existing L3VE interface or L3VE subinterface.
Use undo interface ve-l3vpn to delete an L3VE interface or L3VE subinterface.
Syntax
interface ve-l3vpn { interface-number | interface-number.subnumber }
undo interface ve-l3vpn { interface-number | interface-number.subnumber }
Default
No L3VE interfaces or L3VE subinterfaces exist.

Parameters
interface-number: Specifies the L3VE interface number in the range of 1 to 8192.
interface-number.subnumber: Specifies the L3VE subinterface number. The interface-number argument represents the number of an L3VE interface, in the range of 1 to 8192. The subnumber argument represents the number of the subinterface to be created on the L3VE interface. The value range for the subnumber argument is 1 to 4094.
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
[Sysname-VE-L3VPN100] quit
# Create L3VE subinterface VE-L3VPN 100.10, and enter L3VE subinterface view.
