Service loopback group configuration example
Network requirements
All Ethernet ports on Device A support the tunnel service.
Assign GigabitEthernet 1/0/1 through GigabitEthernet 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 GigabitEthernet 1/0/1 through GigabitEthernet 1/0/3 to service loopback group 1.
[DeviceA] interface gigabitethernet 1/0/1
[DeviceA-GigabitEthernet1/0/1] port service-loopback group 1
[DeviceA-GigabitEthernet1/0/1] quit
[DeviceA] interface gigabitethernet 1/0/2
[DeviceA-GigabitEthernet1/0/2] port service-loopback group 1

# Create the interface Tunnel 1 and set it to GRE mode. The interface will automatically use service
loopback group 1.
