Configuration procedure
1. Configure IP addresses for the tunnel interfaces and related ports on the devices. (Details not
shown.)
2. Configure Device A (the source device):
# Create service loopback group 1, and specify the tunnel service for the group.
<DeviceA> system-view
[DeviceA] service-loopback group 1 type tunnel
# Assign Ten-GigabitEthernet 1/0/3 to service loopback group 1.
[DeviceA] interface ten-gigabitethernet 1/0/3
[DeviceA-Ten-GigabitEthernet1/0/3] port service-loopback group 1
All configurations on the interface will be lost. Continue?[Y/N]:y
[DeviceA-Ten-GigabitEthernet1/0/3] quit
# Create tunnel interface Tunnel 0 that operates in GRE mode, and configure an IP address and
subnet mask for the interface.
[DeviceA] interface tunnel 0 mode gre
[DeviceA-Tunnel0] ip address 50.1.1.1 24
# Configure source and destination IP addresses for Tunnel 0.
[DeviceA-Tunnel0] source 20.1.1.1
[DeviceA-Tunnel0] destination 30.1.1.2
[DeviceA-Tunnel0] quit
