The tunnel interface number is in the A/B/C format, where A, B, and C represent the slot number of a card, the slot number of a sub-card, and the tunnel interface number, respectively. The value ranges of A and B vary with devices, and that of C is from 0 to 1023.
Tunnel Configuration Commands
destination
Syntax
destination ip-address
undo destination
View
Tunnel interface view
Default Level
2: System level
Parameters
ip-address: Tunnel destination IPv4 address.
Description
Use the command destination to specify the destination address for the tunnel interface.
Use the undo destination command to remove the configured tunnel destination address.
By default, no tunnel destination address is configured.
Note that:
l The tunnel destination address is the address of the peer interface receiving packets and should be configured as the source address of the peer tunnel interface.
l Two or more tunnel interfaces using the same encapsulation protocol must have different source and destination addresses.
Related commands: interface tunnel, source.

interface tunnel
Syntax
interface tunnel number
undo interface tunnel number
View
System view
Default Level
2: System level
Parameters
number: Tunnel interface number. The tunnel interface number is in the A/B/C format, where A, B, and C represent the slot number of a card, the slot number of a sub-card, and the tunnel interface number, respectively. The value ranges of A and B vary with devices, and that of C is from 0 to 1023.
Description
Use the interface tunnel command to create a tunnel interface and enter tunnel interface view.
Use the undo interface tunnel command to remove the specified tunnel interface.
By default, there is no tunnel interface on the device.
l Executing the interface tunnel command enters interface view of a specified tunnel. If no tunnel interface is created, executing this command first creates a tunnel and then enters the tunnel interface view.
l A tunnel interface number has only local significance, and therefore, the same interface number or different interface numbers can be set at both ends of a tunnel.
Related commands: display interface tunnel, source, destination, tunnel-protocol.
Examples
# Create the interface tunnel 2/0/3.
<Sysname> system-view
[Sysname] interface tunnel 2/0/3
[Sysname-Tunnel2/0/3]
service-loopback-group
Syntax
service-loopback-group number
undo service-loopback-group
View
Tunnel interface view
Default Level
2: System level
Parameters
number: Service loopback group ID, in the range of 1 to 1024.
Description
Use the service-loopback-group command to reference a service loopback group on the tunnel interface.
Use the undo service-loopback-group command to remove the referenced service loopback group from the tunnel interface.
By default, no service loopback group is referenced on a tunnel interface.
The service loopback group to be referenced must have been configured and have the service type set to tunnel in system view.
One tunnel interface can reference only one service loopback group.
Related commands: service-loopback group in Service Loopback Group Commands in the Access Volume.
Examples
# Create service loopback group 1 of tunnel type.
<Sysname> system-view
[Sysname] service-loopback group 1 type tunnel
# Add a Layer 2 GigabitEthernet interface to service loopback group 1.
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] stp disable
[Sysname-GigabitEthernet1/0/1] port service-loopback group 1
[Sysname-GigabitEthernet1/0/1] quit
# Reference service loopback group 1 on interface tunnel 2.
[Sysname] interface tunnel 2/0/2

source
Syntax
source { ip-address | interface-type interface-number }
undo source
View
Tunnel interface view
Default Level
2: System level
Parameters
ip-address: Tunnel source IPv4 address.
Description
Use the source command to specify the source address or interface of the tunnel interface.
Use the undo source command to remove the configured source address or interface of the tunnel interface.
By default, no source address or interface is specified for the tunnel interface.
Note that:
l The tunnel source address is the address of the interface sending packets and should be configured as the destination address of the peer tunnel interface.
l Two or more tunnel interfaces using the same encapsulation protocol must have different source addresses and destination addresses.
Related commands: interface tunnel, destination.
Examples
# Set the tunnel source address to 192.100.1.1 (or the interface VLAN-interface 100) on the interface Tunnel 2/0/5.
<Sysname> system-view
[Sysname] interface tunnel 2/0/5
[Sysname-Tunnel2/0/5] source 192.100.1.1
Or
<Sysname> system-view
[Sysname] interface tunnel 2/0/5
[Sysname-Tunnel2/0/5] source vlan-interface 100
tunnel-protocol
Syntax
tunnel-protocol ipv6-ipv4 [ 6to4 | isatap ]
undo tunnel-protocol
View
Tunnel interface view
Default Level
2: System level
Parameters
ipv6-ipv4: Sets the tunnel to an IPv6 manual tunnel.
ipv6-ipv4 6to4: Sets the tunnel to IPv6 over IPv4 6to4 tunnel.
ipv6-ipv4 isatap: Sets the tunnel to an IPv6 over IPv4 ISATAP tunnel.
Description
Use the tunnel-protocol command to configure the tunnel mode.
Use the undo tunnel-protocol to restore the default tunnel mode.
By default, the tunnel is a IPv6 manual tunnel.
Note that:
l A proper tunnel mode can be selected for packet encapsulation according to the network topology and application. The same tunnel mode must be configured at both ends of the tunnel. Otherwise, packet delivery will fail.
l Only one automatic tunnel can be configured at the same tunnel source.
Examples
# Specify the tunnel mode as IPv6 over IPv4 6to4 tunnel interface.
<Sysname> system-view
[Sysname] interface tunnel 2/0/2
[Sysname-Tunnel2/0/2] tunnel-protocol ipv6-ipv4 6to4
