GRE over IPv4 tunnel configuration example

Network requirements
Switch A and Switch B are interconnected through the Internet. Two private IPv4 subnets Group 1 and
Group 2 are interconnected through a GRE tunnel between the two switches.

Configuration procedure
NOTE:
Before the configuration, make sure that Switch A and Switch B are reachable to each other.
Configure Switch A

[SwitchA-Vlan-interface101] quit
# Create service loopback group 1, and configure the service type as tunnel.
[SwitchA] service-loopback group 1 type tunnel
# Add port GigabitEthernet 1/0/3 to service loopback group 1, and disable STP and LLDP on the port.
