+interfaces-tunnel(5)
+
+# NAME
+
+*interfaces-tunnel* - Tunnel extensions for the interfaces(5) file format
+
+# DESCRIPTION
+
+The following options set up tunneling interfaces with ifupdown-ng.
+
+# TUNNEL-RELATED OPTIONS
+
+A tunnel interface must have a mode, remote IP and a local IP or device
+set, all other options are optional.
+
+*tunnel-mode* _mode_
+	Denotes the mode for this tunnel. Basically all tunnel modes supported
+	by Linux / iproute2 are supported as well.  This includes but is not
+	limited to _gre_/_gretap_, _ip6gre_/_ip6gretap_, _ipip_/_ip6ip_/_sit_.
+
+*tunnel-local* _IP_
+	Denotes the IP address used as the local tunnel endpoint.  According
+	to the _tunnel-mode_ an IPv4 or IPv6 address has to be given.
+	For compatiblity to ifupdown1 _local_ is an alias for this option.
+
+*tunnel-local-dev* _interface_
+	When the local IP address the tunnel should be established from isn't
+	static and therefore might change (e.g. configured by DHCP or PPP) it
+	might be desireable to just use the address configured on _interface_.
+	When _tunnel-local-dev_ is given instead of _tunnel-local_ ifupdown-ng
+	will try to determine the IP address set on the given _interface_ with
+	respect to the address family required to set up a tunnel of the given
+	_mode_ and use this to set up the tunnel.
+
+*tunnel-remote* _IP_
+	Denotes the IP address used as the remote tunnel endpoint.  According
+	to the _tunnel-mode_ an IPv4 or IPv6 address has to be given.
+	For compatiblity to ifupdown1 _endpoint_ is an alias for this option.
+
+*tunnel-physdev* _interface_
+	Denotes the _interface_ the encapsulated packets should be sent out by.
+	This comes in handy when using VRFs to denote that the local tunnel
+	endpoint should be terminated in VRF _interface_ or the VRF associated
+	with _interface_.
+
+	Note: Depending on the _mode_ of the tunnel either the VRF interface
+	or the real underlay interface may have to given as _interface_.
+
+*tunnel-ttl* _ttl_
+	Denotes the TTL value to use in outgoing packets.  _ttl_ is a number in the
+	range 1 - 255 whereas 0 is a special value meaning that packets inherit the
+	TTL value.  The default for IPv4 tunnels is to inherit the TTL, for IPv6
+	tunnels it's 64.  For compatiblity to ifupdown1 _ttl_ is an alias for this option.
+
+
+
+# IPIP/SIT-RELATED OPTIONS
+
+*tunnel-encap* _encap_
+	Denotes the type of secondary UDP encapsulation to use for this tunnel
+	if any.  Supported _encap_ values are _fou_, _gue_, and _none_.
+	_fou_ indicates Foo-Over-UDP, _gue_ indicates Generic UDP Encapsulation.
+
+# GRE-RELATED OPTIONS
+
+*tunnel-encap* _encap_
+	Denotes the type of secondary UDP encapsulation to use for this tunnel
+	if any.  Supported _encap_ values are _fou_, _gue_, and _none_.
+	_fou_ indicates Foo-Over-UDP, _gue_ indicates Generic UDP Encapsulation.
+
+*tunnel-key* _key_
+	Denotes the_key to used for keyed GRE to allow multiple tunnels between
+	the same two endpoints.  _key_ is either a number or an IPv4 address-
+	like dotted quad.  The key parameter specifies the same key to use in both
+	directions.  The _tunnel-ikey_ and _tunnel-okey_ parameters specify different
+	keys for input and output.  For compatiblity to ifupdown1 _key_ is an alias
+	for this option.
+
+*tunnel-hoplimit* _ttl_
+	Denotes the Hop Limit value to use in outgoing packets for _ip6gre_/_ip6gretap_
+	tunnels.
+
+*tunnel-ignore-df* _bool_
+	Denotes wether to enable/disable IPv4 DF suppression on this tunnel.  Normally
+	datagrams that exceed the MTU will be fragmented; the presence of the DF flag
+	inhibits this, resulting instead in an ICMP Unreachable (Fragmentation Required)
+	message.  Enabling this attribute causes the DF flag to be ignored.
+
+*tunnel-ikey* _key_
+	Denotes the key to used for keyed GRE for packets received.  See _tunnel-key_
+	for details.
+
+*tunnel-okey* _key_
+	Denotes the key to used for keyed GRE for packets sent out.  See _tunnel-key_
+	for details.
+
+*tunnel-pmtudisc* _bool_
+	Denotes wether to enable/disable Path MTU Discovery on this tunnel.  It is
+	enabled by default.  Note that a fixed ttl is incompatible with this option:
+	tunneling with a fixed ttl always makes pmtu discovery.
+
+*tunnel-tos* _tos_
+	Denotes the TOS value to use in outgoing packets.
+
+
+# EXAMPLES
+

+iface gre0
+	tunnel-mode gre
+	tunnel-remote 198.51.100.1

+	#
+	address 192.0.2.42/24
+	address 2001:db8::42/64
+```
+
+A GRE tunnel where the local IP is learned from _eth0_
+
+```
+auto gre1
+iface gre1
+	tunnel-mode gre
+	tunnel-remote 198.51.100.1
+	tunnel-local-dev eth0
+	#
+	address 192.0.2.42/24
+	address 2001:db8::42/64
+```
+
+A GRE tunnel which transfers encapasulated packets via _eth0_ which is part
+of a VRF.
+
+```
+auto eth0
+iface eth0
+	address 203.0.113.2/24
