New page

== Openvswitch VXLAN Hello World example ==

This is very cool. You can create simple and efficient L2 ethernet tunnel between two hosts with L3 (IP) connection.<br>
Later you can add physical interface to the ovs bridge, connect dumb physical L2 switch and interconnect two sites.

=== Open port on ffiewall ===

L2 Ethernet frames are encapsulated in L4 UDP datagrams. Port is 4789.
<pre>
firewall-cmd --add-port=4789/udp --zone=public --permanent
</pre>

=== Create virtual switch and VXLANs ===

<pre>
ovs-vsctl add-br br0
ovs-vsctl add-port br0 vxlan0 -- set interface vxlan0 type=vxlan options:remote_ip=192.168.80.30
ovs-vsctl add-port br0 vxlan0 -- set interface vxlan0 type=vxlan options:remote_ip=192.168.80.20
</pre>

br0 is the virtual switch (bridge) where you can "plug" virtual and physical interfaces
remote_ip is your server's public IP (private in this case, just for testing in LAB)

=== Create and connect internal virtual interface to vitual switch ===

<pre>
ovs-vsctl add-port br0 vi0 -- set Interface vi0 type=internal
ip addr add 192.168.120.10/24 dev vi0
ifconfig vi0 up
</pre>

<pre>
ovs-vsctl add-port br0 vi0 -- set Interface vi0 type=internal
ip addr add 192.168.120.20/24 dev vi0
ifconfig vi0 up
</pre>

=== Tesing ===
Try to ping each other's IP address of vi0. (192.168.120.10 and 192.168.120.20)
