Configuring service loopback groups
A service loopback group supports only unicast tunnel traffic.
The device supports only one service loopback group for each service type. You can use a service loopback group with multiple features.
Member ports in a service loopback group are load balanced.
Configuration procedure
Follow these guidelines when you configure a service loopback group:
· Make sure the ports you are assigning to a service loopback group meet the following requirements:
? The ports are not used for any other purposes. The configuration on a port is removed when it is assigned to a service loopback group.
? The ports support the service type of the service loopback group and are not members of any other service loopback group.
· You cannot change the service type of a service loopback group.
· For correct traffic processing, follow these guidelines:
? Make sure the service loopback group has a minimum of one member port when it is being used by a feature.
? Do not delete the service loopback group when it is being used by a feature.
To configure a service loopback group:

Command |
Remarks |
1. Enter system view. |
system-view |
N/A |
2. Create a service loopback group and specify its service type as tunnel. |
service-loopback group number type tunnel |
N/A |
3. Enter Layer 2 Ethernet interface view. |
interface interface-type interface-number |
N/A |
4. Assign a port to the service loopback group. |
port service-loopback group number |
By default, a service loopback group does not contain ports. |

Network requirements
All Ethernet ports on Device A support the tunnel service.
Assign FortyGigE 1/0/1 through FortyGigE 1/0/3 to a service loopback group to loop GRE packets sent out by the device back to the device.
Configuration procedure
# Create service loopback group 1, and specify its service type as tunnel.
<DeviceA> system-view
[DeviceA] service-loopback group 1 type tunnel
# Assign FortyGigE 1/0/1 through FortyGigE 1/0/3 to service loopback group 1.
[DeviceA] interface fortyGigE 1/0/1
[DeviceA-FortyGigE1/0/1] port service-loopback group 1
[DeviceA-FortyGigE1/0/1] quit
[DeviceA] interface fortyGigE 1/0/2
[DeviceA-FortyGigE1/0/2] port service-loopback group 1
[DeviceA-FortyGigE1/0/2] quit
[DeviceA] interface fortyGigE 1/0/3
[DeviceA-FortyGigE1/0/3] port service-loopback group 1
[DeviceA-FortyGigE1/0/3] quit
# Create the interface Tunnel 1 and set it to GRE mode. The interface will automatically use service loopback group 1.
