Service loopback group configuration example

Network requirements

All Ethernet ports on Device A support the unicast tunnel service. Assign Ten-GigabitEthernet 1/0/1

through Ten-GigabitEthernet 1/0/3 to a service loopback group to support the tunnel service.

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 Ten-GigabitEthernet 1/0/1 through Ten-GigabitEthernet 1/0/3 to service loopback group 1.

[DeviceA] interface ten-gigabitethernet 1/0/1

[DeviceA-Ten-GigabitEthernet1/0/1] port service-loopback group 1

[DeviceA-Ten-GigabitEthernet1/0/1] quit

[DeviceA] interface ten-gigabitethernet 1/0/2

[DeviceA-Ten-GigabitEthernet1/0/2] port service-loopback group 1

[DeviceA-Ten-GigabitEthernet1/0/2] quit

[DeviceA] interface ten-gigabitethernet 1/0/3

[DeviceA-Ten-GigabitEthernet1/0/3] port service-loopback group 1

[DeviceA-Ten-GigabitEthernet1/0/3] quit

# Create tunnel interface 1 operating in GRE mode, which will automatically use service loopback group

1 for completing the forwarding process.
