3
On the device, a tunneled packet cannot be directly routed based on its destination address. It is sent to
a tunnel-type service loopback group, which then delivers the packet to the forwarding module for Layer
3 forwarding.
Configuration procedures
Make sure the gateways can reach each other at IPv4.

# Configure IP addresses for other interfaces, as shown in

# Create service loopback group 1, and specify its service type as
tunnel

# Assign GigabitEthernet 1/0/3 to service loopback group 1.
