Hi Praveen,
The arp entries are learned properly, if the packets are reaching at br1.
Can you please confirm what flow rules are populated on br1 using ,
ovs-ofctl dump-flows br1
If there is no rules present, please add a rule to forward packet to the
physical port as follows,
ovs-ofctl add-flow br1 idle_timeout=0,in_port=LOCAL,action=output:1
Regards

Hi Sugesh,
Thanks for the reply.
arp entries are show in vs-appctl tnl/arp/show command. but it seems o packet
is coming to the bridge with physical port.
I have already tried to set using tnl/arp/set command but it seems set is not
present in openvswitch 2.4
it returns the following error.
"
ovs-appctl tnl/arp/set br0 10.200.0.6 02:11:22:44:55:11
"tnl/arp/set" is not a valid command
ovs-appctl: ovs-vswitchd: server returned an error "
One important thing is to note that i was using dpdk-2.0.0. does that make any
difference?
Thanks
Praveen

Subject: [ovs-discuss] Test with vxlan using ovs-dpdk (2.4)
HI,
I am Praveen,
I am trying a specific test scenario using ovs-dpdk.
Test set up
-------------------
from the traffgen vlan packets are coming to dpdk interface its stripped using
ovs command.
and sending to a vxlan interface which is comnnected in theo other dpdk
interface and send back to traffgen.
i have done the vxlan set up similar to the sample test case.
https://github.com/openvswitch/ovs/blob/master/README-native-tunneling.md
the issue is that from the sumpflows i can see that packets are send to vxlan
but it is not going to the other bridge.
the same scenario is working without dpdk.
I am using openvswitch-2.4.0.
Linux (without dpdk)
---------------------------------
ovs-vsctl add-br br0
ovs-vsctl add-port br0 eth0
ovs-vsctl add-port br0 vxlan0 -- set interface vxlan0 type=vxlan
options:remote_ip=10.200.0.6
ovs-ofctl add-flow br0
dl_vlan=1,dl_dst=02:11:22:44:55:22,actions=strip_vlan,output:2
ovs-vsctl add-br br1
ovs-vsctl add-port br1 eth1
ip a a 10.200.0.5/24<http://10.200.0.5/24> dev br1
arp -s 10.200.0.6 02:11:22:44:55:11 -i eth2
and from the traffgen i am sending traffic with dst mac 02:11:22:44:55:22 and
vlan id 1.
it is correctly working.
ovs-dpdk
------------------
started ovs-dpdk ::
ovs-vswitchd --dpdk -c 0x1 -n 4 -- unix:$DB_SOCK --pidfile --detach
ovs-vsctl add-br br0 -- set bridge br0 datapath_type=netdev
ovs-vsctl add-port br0 dpdk0 -- set Interface dpdk0 type=dpdk
ovs-vsctl add-br br1 -- set bridge br1 datapath_type=netdev
ovs-vsctl add-port br1 dpdk1 -- set Interface dpdk1 type=dpdk
ovs-vsctl add-port br0 vxlan0 -- set interface vxlan0 type=vxlan
options:remote_ip=10.200.0.6
ovs-ofctl add-flow br0
dl_vlan=1,dl_dst=02:11:22:44:55:22,actions=strip_vlan,output:2
ip a a 10.200.0.5/24<http://10.200.0.5/24> dev br1
arp -s 10.200.0.6 02:11:22:44:55:11 -i eth2
here i have started the ovs-dpddk and do the same set up
but packets are not seen in bridge1 (br1) and in traffgen.
is there any specif configuration i need to do in ovs-dpdk
could it be because of the arp?
Is there a way to set static arp to the ovs-dpdk?

Could you help in identifying the problem?
Thanking you in advance
