Usage guidelines

	CAUTION: The default command might interrupt ongoing network services. Make sure you are fully aware of the impact of this command when you use it on a live network.

 

This command might fail to restore the default settings for some commands for reasons such as command dependencies or system restrictions. Use the display this command in interface view to identify these commands. Use their undo forms or follow the command reference to restore their default settings. If your restoration attempt still fails, follow the error message instructions to resolve the problem.

interface ve-l2vpn

Use interface ve-l2vpn to create an L2VE interface and enter its view, or enter the view of an existing L2VE interface.

Use undo interface ve-l2vpn to delete an L2VE interface.

Syntax

Default

No L2VE interfaces exist.

Views

Predefined user roles

network-admin

Parameters

interface-number: Specifies the L2VE interface number in the range of 1 to 2046.

Usage guidelines

A VE-L2VPN interface (an L2VE interface) 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.

Examples

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

<Sysname> system-view

[Sysname] interface ve-l2vpn 100

[Sysname-VE-L2VPN100]

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.

Views

Predefined user roles

network-admin

Parameters

interface-number: Specifies the L3VE interface number in the range of 1 to 2046.

interface-number.subnumber: Specifies the L3VE subinterface number. 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

mac-address

Use mac-address to configure a MAC address for an L3VE interface.

Use undo mac-address to restore the default.

Syntax

mac-address mac-address

undo mac-address

Default

The MAC address of an L3VE interface is assigned by the device.

Views

Predefined user roles

network-admin

Parameters

mac-address: Specifies a MAC address in H-H-H format.

Usage guidelines

This command is supported only when the system operating mode is WAN SDN. For more information about system operating modes, see device management commands in Fundamentals Command Reference.

This command is supported only on CSPEX (except CSPEX-1204 and CSPEX-1104-E) and CEPC cards.

Examples

# Configure 0001-0001-0001 as the MAC address of L3VE interface VE-L3VPN 100.

<Sysname> system-view

[Sysname] interface ve-l3vpn 100

[Sysname-VE-L3VPN100] mac-address 1-1-1

mtu

Use mtu to set the MTU for an interface.

Use undo mtu to restore the default.

Syntax

mtu size

undo mtu

Default

The default MTU is 1500 bytes.

Views

L3VE interface view

L3VE subinterface view

Predefined user roles

network-admin

Parameters

mtu-size: Specifies the MTU in 46 to 9600 bytes.

Usage guidelines

As a best practice, set the MTU of an L3VE interface or L3VE subinterface to a value larger than 1280 bytes if the device contains CSPC-GE16XP4L-E, CSPC-GE24L-E, CSPC-GP24GE8XP2L-E, CSPEX, and CEPC cards. If the MTU of an L3VE interface/subinterface is less than 1280 bytes, the interface/subinterface uses the 1280-byte MTU to fragment packets received from those cards.

Examples

# Set the MTU for VE-L3VPN 100 to 1430 bytes.

<Sysname> system-view

[Sysname] interface ve-l3vpn 100

[Sysname-VE-L3VPN100] mtu 1430
