GRETAP tunnels operate on layer 2 of the ISO/OSI model. To use a GRETAP tunnel, you only have to change the mode: For IPv4 `gretap` and for IPv6 `ip6gretap`.

`<vni>` (**V**irtual Extensible LA**N** **ID** ) is the ID of the VLAN. This can range from 1 to 16777216 (2^24). It must be the same for both peers and must not already be used.
`<dstport>` is the port which is used for the VXLAN connection. It must be open on UDP. The port must be the same for both peers. Officially VXLAN has port 4789, but for historical reasons Linux uses port default 8472. If you specify a 0 as port, the default port default 8472 is used. If you don't specify a port, you get a warning.
