.. _clicmd_src_plugins_geneve: =============================================================== Geneve cli reference =============================================================== create geneve tunnel ------------------------------------------------------------------------- .. code-block:: console create geneve tunnel local {remote |group } vni [encap-vrf-id ] [decap-next [l2|node ]] [l3-mode] [del] Add or delete a GENEVE Tunnel. GENEVE provides the features needed to allow L2 bridge domains (BDs) to span multiple servers. This is done by building an L2 overlay on top of an L3 network underlay using GENEVE tunnels. This makes it possible for servers to be co-located in the same data center or be separated geographically as long as they are reachable through the underlay L3 network. You can refer to this kind of L2 overlay bridge domain as a GENEVE segment.

By adding the IPv4 geneve-bypass graph node to an interface, the node checks for and validate input geneve packet and bypass ip4-lookup, ip4-local, ip4-udp-lookup nodes to speedup geneve packet forwarding. This node will cause extra overhead to for non-geneve packets which is kept at a minimum.
