+.SH DESCRIPTION
+.B tunnel
+objects are tunnels, encapsulating packets in IP packets and then
+sending them over the IP infrastructure.
+The encapsulating (or outer) address family is specified by the
+.B -f
+option. The default is IPv4.
+
+.TP
+.B ip tunnel add
+add a new tunnel
+.TP
+.B ip tunnel change
+change an existing tunnel
+.TP
+.B ip tunnel delete
+destroy a tunnel
+.RS
+.TP
+.BI name " NAME " (default)
+select the tunnel device name.
+
+.TP
+.BI mode " MODE"
+set the tunnel mode. Available modes depend on the encapsulating address family.
+.br
+Modes for IPv4 encapsulation available:
+.BR ipip ", " sit ", " isatap ", " vti ", and " gre "."
+.br
+Modes for IPv6 encapsulation available:
+.BR ip6ip6 ", " ipip6 ", " ip6gre ", " vti6 ", and " any "."
+
+.TP
+.BI remote " ADDRESS"
+set the remote endpoint of the tunnel.
+
+.TP
+.BI local " ADDRESS"
+set the fixed local address for tunneled packets.
+It must be an address on another interface of this host.
+
+.TP
+.BI ttl " N"
+.TP
+.BI hoplimit " N"
+set a fixed TTL (IPv4) or hoplimit (IPv6)
+.I N
+on tunneled packets.
+.I N
+is a number in the range 1--255. 0 is a special value
+meaning that packets inherit the TTL value.
+The default value for IPv4 tunnels is:
+.BR "inherit" .
+The default value for IPv6 tunnels is:
+.BR "64" .
+
+
+.TP
+.BI tos " T"
+.TP
+.BI dsfield " T"
+.TP
+.BI tclass " T"
+set the type of service (IPv4) or traffic class (IPv6) field on
+tunneled packets, which can be specified as either a two-digit
+hex value (e.g. c0) or a predefined string (e.g. internet).
+The value
+.B inherit
+causes the field to be copied from the original IP header. The
+values
+.BI "inherit/" STRING
+or
+.BI "inherit/" 00 ".." ff
+will set the field to
+.I STRING
+or
+.IR 00 ".." ff
+when tunneling non-IP packets. The default value is 00.
+
+.TP
+.BI dev " NAME"
+bind the tunnel to the device
+.I NAME
+so that tunneled packets will only be routed via this device and will
+not be able to escape to another device when the route to endpoint
+changes.
+
+.TP
+.B nopmtudisc
+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.
+
+.TP
+.B ignore-df
+enable 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.
+
+.TP
+.BI key " K"
+.TP
+.BI ikey " K"
+.TP
+.BI okey " K"
+.RB ( " only GRE tunnels " )
+use keyed GRE with key
+.IR K ". " K
+is either a number or an IP address-like dotted quad.
+The
+.B key
+parameter sets the key to use in both directions.
+The
+.BR ikey " and " okey
+parameters set different keys for input and output.
+
+.TP
+.BR csum ", " icsum ", " ocsum
+.RB ( " only GRE tunnels " )
+generate/require checksums for tunneled packets.
+The
+.B ocsum
+flag calculates checksums for outgoing packets.
+The
+.B icsum
+flag requires that all input packets have the correct
+checksum. The
+.B csum
+flag is equivalent to the combination
+.BR "icsum ocsum" .
+
+.TP
+.BR seq ", " iseq ", " oseq
+.RB ( " only GRE tunnels " )
+serialize packets.
+The
+.B oseq
+flag enables sequencing of outgoing packets.
+The
+.B iseq
+flag requires that all input packets are serialized.
+The
+.B  seq
+flag is equivalent to the combination
+.BR "iseq oseq" .
+.B It doesn't work. Don't use it.
+
+.TP
+.BI encaplimit " ELIM"
+.RB ( " only IPv6 tunnels " )
+set a fixed encapsulation limit. Default is 4.
+
+.TP
+.BI flowlabel " FLOWLABEL"
+.RB ( " only IPv6 tunnels " )
+set a fixed flowlabel.
+
+.TP
+.BI allow-localremote
+.RB ( " only IPv6 tunnels " )
+allow remote endpoint on the local host.
