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.
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.
firewall-cmd --add-port=4789/udp --zone=public --permanent
Create virtual switch and VXLANs
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
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
ovs-vsctl add-port br0 vi0 -- set Interface vi0 type=internal ip addr add 192.168.120.10/24 dev vi0 ifconfig vi0 up
ovs-vsctl add-port br0 vi0 -- set Interface vi0 type=internal ip addr add 192.168.120.20/24 dev vi0 ifconfig vi0 up
Tesing
Try to ping each other's IP address of vi0. (192.168.120.10 and 192.168.120.20)
