I Think I figured out the reason and will work on it as peer port are configured on switch. No need help for this issue now. Thanks

You can see a SNAP packet received on br-ex bridge port 2 got forwarded to br-int and br-data bridges below. How could this happen? # ovs-dpctl dump-flows skb_priority(0),in_port(2),eth(src=00:9c:02:79:1b:75,dst=01:14:c2:44:1e:cc),eth_type(0/0xffff), packets:0, bytes:0, used:never, actions:1,3,5,4 # ovs-dpctl show system@ovs-system: lookups: hit:0 missed:3913 lost:0 flows: 0 masks: hit:2009 total:0 hit/pkt:0.51 port 0: ovs-system (internal) port 1: br-ex (internal) port 2: eth4 port 3: br-int (internal) port 4: br-data (internal) port 5: eth3 # ovs-vsctl show f53f59be-9e8b-4e65-bc96-8334b25a3510 Bridge br-ex Port br-ex Interface br-ex type: internal Port phy-br-ex Interface phy-br-ex type: patch options: {peer=int-br-ex} Port "eth4" Interface "eth4" Bridge br-data Port phy-br-data Interface phy-br-data type: patch options: {peer=int-br-data} Port "eth3" Interface "eth3" Port br-data Interface br-data type: internal Bridge br-int fail_mode: secure Port int-br-ex Interface int-br-ex type: patch options: {peer=phy-br-ex} Port int-br-data Interface int-br-data type: patch options: {peer=phy-br-data} Port br-int Interface br-int type: internal ovs_version: "2.3.0" # ifconfig eth4 eth4 Link encap:Ethernet HWaddr 52:54:00:5f:13:49 inet6 addr: fe80::5054:ff:fe5f:1349/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:3730 errors:0 dropped:10 overruns:0 frame:0 TX packets:79 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:262680 (256.5 KiB) TX bytes:6518 (6.3 KiB) # ifconfig eth3 eth3 Link encap:Ethernet HWaddr 52:54:00:29:b8:4f inet6 addr: fe80::5054:ff:fe29:b84f/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:308 errors:0 dropped:28 overruns:0 frame:0 TX packets:3672 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 Thanks a lot!-weiwen RX bytes:24032 (23.4 KiB) TX bytes:258738 (252.6 KiB)
