- * 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_gbp 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_gbp_tunnel42:
- * @cliexcmd{create vxlan_gbp 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_gbp_tunnel23:
- * @cliexcmd{create vxlan_gbp tunnel src 10.0.3.1 group 239.1.1.1 GigabitEthernet0/8/0 instance 23}
