Hi,
I have a two VM setup with two containers (simulated by veth pairs) on each VM.
I am able to ping from containers on host A to host B and vice versa when
I use gre tunnels. However, when I replace gre by vxlan, the ping doesn't work
anymore. What am I missing?
Host A
[root@localhost ~]# ovs-vsctl show
60741b68-4d89-4cee-989c-1e5a7718731e
Bridge "br0"

Interface vethc

Port "br0"
Interface "br0"
type: internal
ovs_version: "2.3.0"
[root@localhost ~]# ovs-ofctl -O OpenFlow13 dump-flows br0

gre 13535 1 openvswitch
vxlan 37333 1 openvswitch
libcrc32c 12603 1 openvswitch
[root@localhost ~]#
The tunnels are created using --
ovs-vsctl add-port br0 vxlan0 -- set interface vxlan0 type=vxlan
option:remote_ip=192.168.122.26 ofport_request=10
When using gre --
ovs-vsctl add-port br0 gr00 -- set interface gr0 type=gre
option:remote_ip=192.168.122.26 ofport_request=10
ping works with gre but not with vxlan.
Thanks
