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.

Examples

# Restore the default settings of Tunnel 1.

<Sysname> system-view

[Sysname] interface tunnel 1

[Sysname-Tunnel1] default

description

Use description to configure the description of an interface.

Use undo description to restore the default.

Parameters

ipv4-address: Specifies the tunnel destination IPv4 address.

ipv6-address: Specifies the tunnel destination IPv6 address.

dhcp-alloc interface-type interface-number: Specifies an interface by its type and number to receive DHCPv6 packets.

Usage guidelines

For a manual tunnel interface, you must configure the destination address. For an automatic tunnel interface, you do not need to configure the destination address.

The tunnel destination address must be the address of the receiving interface on the tunnel peer. It is used as the destination address of tunneled packets.

The destination address of the local tunnel interface must be the source address of the peer tunnel interface. The source address of the local tunnel interface must be the destination address of the peer tunnel interface.

Examples

# The interface GigabitEthernet 3/1/1 on Sysname 1 uses the IP address 193.101.1.1 and the interface GigabitEthernet 3/1/1 on Sysname 2 uses the IP address 192.100.1.1. Configure the source address 193.101.1.1 and destination address 192.100.1.1 for the tunnel interface on Sysname 1.

Usage guidelines

Use this command on the AFTR's interface connected to the public IPv4 network, so the AFTR can forward IPv4 packets to the B4 router through the DS-Lite tunnel.

You cannot enable DS-Lite tunneling on a DS-Lite tunnel interface on the AFTR.

Examples

# Enable DS-Lite tunneling on GigabitEthernet 3/1/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 3/1/1

[Sysname-GigabitEthernet3/1/1] ds-lite enable

interface tunnel

Use interface tunnel to create a tunnel interface, specify the tunnel mode, and enter tunnel interface view, or enter the view of an existing tunnel interface.

Use undo interface tunnel to delete a tunnel interface.

Syntax

interface tunnel number [ mode { ds-lite-aftr | gre | ipv4-ipv4 | ipv6-ipv4 [ 6to4 | isatap ] | mpls-te | vxlan | vxlan-dci } ]

undo interface tunnel number

Default

Parameters

number: Specifies the number of the tunnel interface, in the range of 0 to 32767. The number of tunnel interfaces that can be created is restricted by the total number of interfaces and the memory.

mode ds-lite-aftr: Specifies the DS-Lite tunnel mode on the AFTR.

mode gre: Specifies the GRE/IPv4 tunnel mode.

mode ipv4-ipv4: Specifies the IPv4 over IPv4 tunnel mode.

mode ipv6-ipv4: Specifies the IPv6 over IPv4 manual tunnel mode.

mode ipv6-ipv4 6to4: Specifies the 6to4 tunnel mode.

mode ipv6-ipv4 isatap: Specifies the ISATAP tunnel mode.

mode mpls-te: Specifies the MPLS TE tunnel mode.

mode vxlan: Specifies the IPv4 VXLAN tunnel mode.

mode vxlan-dci: Specifies the IPv4 VXLAN-DCI tunnel mode.

Usage guidelines

To create a new tunnel interface, you must specify the tunnel mode in this command. To enter the view of an existing tunnel interface, you do not need to specify the tunnel mode.

A tunnel interface number is locally significant. The tunnel interfaces on the two ends of a tunnel can use the same or different interface numbers.

Examples

# Create GRE/IPv4 tunnel interface Tunnel 1 and enter tunnel interface view.

mtu

Use mtu to set the MTU on a tunnel interface.

Use undo mtu to restore the default.

Syntax

mtu size

undo mtu

Default

If the tunnel interface has never been up, the MTU is 1500 bytes.

If the tunnel interface is up, its MTU is identical to the outgoing interface's MTU minus the length of the tunnel headers. The outgoing interface is automatically obtained through routing table lookup based on the tunnel destination address.

Tunnel interface view

Predefined user roles

network-admin

Parameters

size: Specifies the MTU. The value range for this argument varies by device model.

Usage guidelines

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

A tunnel interface does not fragment IP packets if the packets’ incoming interfaces are on the CSPC (except CSPC-GE16XP4L-E, CSPC-GE24L-E, and CSPC-GP24GE8XP2L-E) or CMPE-1104 cards.

After you configure an MTU for a tunnel interface, the configured MTU applies regardless of the tunnel interface status (up/down) and the outgoing interface MTU.

To avoid fragmentation after tunnel encapsulation, set the tunnel interface MTU no greater than the value of the outgoing interface MTU minus the length of the tunnel headers.

Examples

# Set the MTU on Tunnel 1 to 9000 bytes.

<Sysname> system-view

[Sysname] interface tunnel 1

[Sysname-Tunnel1] mtu 9000

Parameters

vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters.

Usage guidelines

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

After this command is executed, the device looks up the routing table of the specified VPN instance to forward tunneled packets on the tunnel interface.

For a tunnel interface to come up, the tunnel source and destination must belong to the same VPN instance. To specify a VPN instance for the tunnel source, use the ip binding vpn-instance command on the tunnel source interface.

If the tunnel peer requires keepalive, you must make sure the local tunnel interface and tunnel source interface belong to the same VPN instance.

Examples

# Specify VPN instance vpn10 for the tunnel destination on Tunnel 1.
