Configuring IP parameters
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.
