<p><b>New page</b></p><div>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:<br />
* VLAN interfaces on L3 switches, allowing it to provide access to all ports on a VLAN<br />
* subinterfaces on routed interfaces on routers, allowing you to constrain it to a particular VLAN<br />
* an entire routed interface on a router, allowing you to trunk VLANs through it.<br />
