[ovs-discuss] connect vxlan to localhost

[Miroslav Kubiczek]

Hi Folks,

I'm struggling with the %subj%. The problem is that OVS is allocating 
the same port on both sides (src and dst) for vxlan port. So if I'm 
running my UDP server on port 4789 and then starting the bridge, the 
following 'add-port' command will fail:

#-----
# ovs-vsctl add-br br0 \
          -- set bridge br0 other-config:datapath-id=0000000000000001  \
          -- add-port br0 ens224 \
          -- add-port br0 ens256 \
          -- set-controller br0 tcp:127.0.0.1:6653
# ovs-vsctl add-port br0 vtep -- set interface vtep type=vxlan 
option:remote_ip=10.10.12.135 option:key=flow ofport_request=10

ovs-vsctl: Error detected while setting up 'vtep': could not add network 
device vtep to ofproto (Address already in use). See ovs-vswitchd log 
for details.
ovs-vsctl: The default log directory is "/var/log/openvswitch".
#-----

Can someone recommend a solution or a workaround (docker/kvm or anything 
simpler)?

Thanks

Miro
