If you need to run a Layer 2 circuit over a Layer 3 network, you can set up an L2TP tunnel. It can be applied to a variety of interfaces:

  • VLAN interfaces on L3 switches, allowing it to provide access to all ports on a VLAN
  • subinterfaces on routed interfaces on routers, allowing you to constrain it to a particular VLAN
  • an entire routed interface on a router, allowing you to trunk VLANs through it.
