# VIRTUAL INTERFACES

The Virtual interfaces module allows managing, adding or deleting virtual network elements. Depending on their nature, these virtual interfaces can be used in a dynamic routing configuration (loopback interfaces), or to set up tunnels (GRE interfaces) or routed tunnels (IPsec interfaces).

The window for configuring virtual interfaces consists of 3 tabs:

- IPsec interfaces (VTI),

- GRE interfaces,

- Loopback.
