154 Ethernet over GRE and Ethernet over L2TPv3. These are called vec0.
241 * GRE and L2TPv3 allow connections to all of: local machine, remote
421 GRE socket transport
426 vecX:transport=gre,src=$src_host,dst=$dst_host
429 This will configure an Ethernet over ``GRE`` (aka ``GRETAP`` or
430 ``GREIRB``) tunnel which will connect the UML instance to a ``GRE``
431 endpoint at host dst_host. ``GRE`` supports the following additional
434 * ``rx_key=int`` - GRE 32-bit integer key for rx packets, if set,
437 * ``tx_key=int`` - GRE 32-bit integer key for tx packets, if set
440 * ``sequence=[0,1]`` - enable GRE sequence
448 * GRE checksum is not presently supported
450 GRE has a number of caveats:
452 * You can use only one GRE connection per IP address. There is no way to
453 multiplex connections as each GRE tunnel is terminated directly on
475 Additionally, GRE has been tested versus a variety of network equipment.
477 Privileges required: GRE requires ``CAP_NET_RAW``
485 For example, most devices which support L2TPv3 also support GRE.
507 functionality as GRE key, more to prevent misconfiguration than provide
