Service loopback group configuration example

Network requirements

All the Ethernet ports of Device A support the tunnel service. Assign Ethernet 1/0/1 through Ethernet
1/0/3 to a service loopback group to increase bandwidth and achieve load sharing for tunnel traffic.

Configuration procedure

# Create service loopback group 1, and specify the service type as tunnel (unicast tunnel service).
<DeviceA> system-view
[DeviceA] service-loopback group 1 type tunnel
# Disable MSTP, LLDP, and NDP on Ethernet 1/0/1 through Ethernet 1/0/3 and then assign them to
service loopback group 1.
[DeviceA] interface ethernet 1/0/1
[DeviceA-Ethernet1/0/1] undo stp enable
[DeviceA-Ethernet1/0/1] undo lldp enable
[DeviceA-Ethernet1/0/1] undo ndp enable
[DeviceA-Ethernet1/0/1] port service-loopback group 1
[DeviceA-Ethernet1/0/1] quit
[DeviceA] interface ethernet 1/0/2
[DeviceA-Ethernet1/0/2] undo stp enable
[DeviceA-Ethernet1/0/2] undo lldp enable
[DeviceA-Ethernet1/0/2] undo ndp enable
[DeviceA-Ethernet1/0/2] port service-loopback group 1
[DeviceA-Ethernet1/0/2] quit
[DeviceA] interface ethernet 1/0/3
[DeviceA-Ethernet1/0/3] undo stp enable
[DeviceA-Ethernet1/0/3] undo lldp enable

Remarks
By default, a port does not belong to any
service loopback group.
You can configure this command on
different ports to assign multiple ports to a
service loopback group.
