-name: Virtual eXtensible LAN
-maintainer: John Lo <loj@cisco.com>
-features:
- - VXLAN tunnel for support of L2 overlay/virtual networks (RFC-7348)
- - Support either IPv4 or IPv6 underlay network VTEPs
- - Flooding via headend replication if all VXLAN tunnels in BD are unicast ones
- - Multicast VXLAN tunnel can be added to BD to flood via IP multicast
- - VXLAN encap with flow-hashed source port for better underlay IP load balance
- - VXLAN decap optimization via vxlan-bypass IP feature on underlay interfaces
- - VXLAN decap HW offload using flow director with DPDK on Intel Fortville NICs
-description: "Virtual eXtensible LAN (VXLAN) tunnels support L2 overlay networks that span L3 networks"
-state: production
-properties: [API, CLI, MULTITHREAD]

- *
- * VXLAN 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 VXLAN 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 VXLAN
- * (Virtual eXtensible VLAN) segment.

- * Add or delete a VXLAN Tunnel.
- *
- * VXLAN 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 VXLAN 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 VXLAN
- * (Virtual eXtensible VLAN) segment.
- *
- * @cliexpar
- * Example of how to create a VXLAN Tunnel:
- * @cliexcmd{create vxlan tunnel src 10.0.3.1 dst 10.0.3.3 vni 13 encap-vrf-id
- 7}
- * Example of how to create a VXLAN Tunnel with a known name, vxlan_tunnel42:
- * @cliexcmd{create vxlan tunnel src 10.0.3.1 dst 10.0.3.3 instance 42}
- * Example of how to create a multicast VXLAN Tunnel with a known name,
- vxlan_tunnel23:
- * @cliexcmd{create vxlan tunnel src 10.0.3.1 group 239.1.1.1
- GigabitEthernet0/8/0 instance 23}
- * Example of how to create a VXLAN Tunnel with custom udp-ports:
- * @cliexcmd{create vxlan tunnel src 10.0.3.1 dst 10.0.3.3 vni 13 src_port
- 59000 dst_port 59001}
