Example of a GRE IP tunnel configuration
In this example, a GRE IP Tunnel is configured between the device A switch and the device B switch.
Traffic between networks 10.10.1.0/24 and 10.10.2.0/24 is encapsulated in a GRE IP packet sent
through the tunnel on the 10.10.3.0 network. and unpacked and sent the destination network. A
static route is configured at each router to go through the tunnel interface to the target network.
NOTE
To set the loopback port, the tunnel mode must be set to GRE IP.
