You can dump-flows from datapath and check what is happening to the packets. ovs-appctl dpctl/dump-flows >>>>[Sugesh] My 2 cents I assume eth0 is DPDK port, in that case you cannot tcpdump on those ports. Can you please verify the arp entries configured on the OVS ?? ovs-appctl tnl/arp/show br0 must have the arp entry for “10.53.87.242” br-vxlan must have the arp entry for “10.53.87.254” If they are missing you can set them using ovs-appctl tnl/arp/set br0 10.53.87.242 <MAC address of br-vxlan> ovs-appctl tnl/arp/set br-vxlan 10.53.87.254 <MAC address of remote end>
