Hi All,
I have OVS bridge (br-int) on 3 different machines
(192.168.100.101/102/103 <http://192.168.100.101/102/103>).
I have created tunnel ports on these 3 machines using:
# ovs-vsctl add-port br-int tun0 -- set interface tun0 type=vxlan
options:remote_ip=192.168.100.102 options:key=<vni>
====> port number:2
If my understanding is not wrong, if we have multiple tunnel ports on
br-int, the packet goes to a tunnel port based on vni.
If you mean received packet, then yes. If you create a vxlan tunnel
with a key set, then only VXLAN packets with that VNI will be received
on the port. The default key/VNI is 0.
If you mean sent packets, then packets go to a certain tunnel port based
on existing flows.
I want to understand how ovs-vswitchd passes a packet from remote node
to a tunnel port.
Also does ovs-vswitchd uses the vxlan_udp_port for any of the
processing???
A listening UDP socket is opened on the configured port.
