Configuration Example
Network requirements
Ports of Device A support the tunnel service. Assign GigabitEthernet 2/0/1 through GigabitEthernet
2/0/3 to a service loopback group to increase bandwidth and achieve load sharing.
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 on GigabitEthernet 2/0/1 through GigabitEthernet 2/0/3 and then assign them to
service loopback group 1.
[DeviceA] interface gigabitethernet 2/0/1
[DeviceA-GigabitEthernet2/0/1] undo stp enable
[DeviceA–GigabitEthernet2/0/1] undo lldp enable
[DeviceA-GigabitEthernet2/0/1] port service-loopback group 1
[DeviceA-GigabitEthernet2/0/1] interface gigabitethernet 2/0/2
[DeviceA-GigabitEthernet2/0/2] undo stp enable
[DeviceA-GigabitEthernet2/0/2] undo lldp enable
[DeviceA-GigabitEthernet2/0/2] port service-loopback group 1
[DeviceA-GigabitEthernet2/0/2] interface gigabitethernet 2/0/3
[DeviceA-GigabitEthernet2/0/3] undo stp enable
[DeviceA-GigabitEthernet2/0/3] undo lldp enable
[DeviceA-GigabitEthernet2/0/3] port service-loopback group 1
[DeviceA-GigabitEthernet2/0/3] quit
# Create a logical interface Tunnel 1 and reference service loopback group 1 on Tunnel 1.
[DeviceA] interface tunnel 1
