 # Handles creation and destruction of IP-in-IP or GRE tunnels over the given
 # topology. Supports both flat and hierarchical models.
 #
 # Flat Model:
 # Overlay and underlay share the same VRF.
 # SW1 uses default VRF so tunnel has no bound dev.
 # SW2 uses non-default VRF tunnel has a bound dev.
