Generate/require checksums for tunneled packets.

The ocsum flag calculates checksums for outgoing packets. The icsum flag requires that all input packets have the correct checksum. The csum flag is equivalent to the combination icsum ocsum .

Specifies the physical device to use for tunnel endpoint communication.

SecondaryUdpEncapsulations

Specifies if UDP checksums are enabled in the secondary encapsulation.

TODO: No doc in man.

Specifies if Remote Checksum Offload is enabled. This is only applicable for Generic UDP Encapsulation.

See

['encap-sport']

Make this tunnel externally controlled (e.g. ip route encap).

See

csum

Enables/disables 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.

key

See

seq

Use keyed GRE with key KEY.

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 ikey and okey parameters specify different keys for input and output.

Specifies the fixed local address for tunneled packets. It must be an address on another interface on this host.

Enables/disables 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.

Specifies the remote address of the tunnel.

Serialize packets.

The seq flag enables sequencing of both incoming and outgoing packets. The oseq flag enables sequencing of outgoing packets. The iseq flag requires that all input packets are serialized.

Specifies the TOS value to use in outgoing packets.

Specifies the TTL value to use in outgoing packets.
