GRE tunnel connecting remote networks

This section presents a sample configuration for a basic GRE tunnel between the WEST and EAST Vyatta router. First, WEST is configured, and then EAST.

This basic tunnel is not protected by a key, which means that it is not secure and would not be suitable for a production network unless otherwise secured.

When you finish the steps, these systems are configured as shown in the following figure. In the figure, note that the remote endpoint must be reachable.
