13.4 GRE

Generic Routing Encapsulation (GRE) is a network protocol that encapsulates other pro-
tocols and transports them in the form of IP tunnels to the specified recipients.
The specification of the GRE protocol is available in two versions:
• GRE V.1 for use in PPTP connections (RFC 2637, configuration in the PPTP menu)
• GRE V.0 (RFC 2784) for general encapsulation using GRE
In this menu you can configure a virtual interface for using GRE V.0. The data traffic
routed over this interface is then encapsulated using GRE and sent to the specified recipi-
ent.
