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

Dear Experts,
Need your help on OVS to explain this scary flow forwarding on Debian OS with OVS 2.3. 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 at 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
