Hi i am newbie in Openvswitch and trying to create a VXLAN tunnel. I am
having issue in connectivity. I am not able to ping the isolated bridges
through VXLAN tunnel. The tunnel end points do have the connectivity. Here
is my configuration:
Host 1:
Bridge "br0"
Port "br0"
Interface "br0"
type: internal
Port "eth0"
Interface "eth0"
Bridge "br1"
Port "vxlan1"
Interface "vxlan1"
type: vxlan
options: {key=flow, remote_ip="192.168.1.102"}
Port "br1"
Interface "br1"
type: internal

Interestingly, the VXLAN is not showing up as port in ovs-dpctl show output:
root at shahryarvm2-VirtualBox:~# ovs-dpctl show
system at ovs-system:
lookups: hit:70 missed:36 lost:0
flows: 2
port 0: ovs-system (internal)
port 1: br0 (internal)
port 2: eth0
port 3: tep0 (internal)
port 4: br1 (internal)
And i got the following message in the logs:
2013-07-26T18:11:02Z|00011|dpif|WARN|system at ovs-system: failed to add
vxlan1 as port: Address family not supported by protocol
What does it mean by address family not supported by protocol? .It seems
that VXLAN is not working at all. I know i am missing some important part
of the configuration. Could somebody please help me. Thanks!
