Tunnel configuration examples
The following examples have some common elements.
- Any Ethernet (data plane) or loopback interface to be used must already be configured. The examples do not show these configurations.
- The examples show both Ethernet and loopback interfaces being configured as tunnel endpoints. Configuring a loopback interface as the tunnel endpoint is advantageous in systems in which multiple paths between tunnel endpoints exist because the tunnel does not fail if an Ethernet interface fails.
