Hi Cascardo,
Appreciated your quick response and find my below inline comment for
resolving the issue .
What is your bridge topology?
Laxmikanta:-My topology is very simple back to back connection.
Query-->
<--Join
TG1(As a Server) ----------------------------
OVS2.3.9-------------------------------TG2(As a Host).
Can you send ovs-vsctl show?
Laxmikanta :-
[root@Iron vswitchd]# ovs-vsctl show
6d16c545-2a2a-46bf-bfee-be3dc5f408e8
Bridge "br0"
Port "enp9s0f0"
Interface "enp9s0f0"
Port "enp9s0f3"
Interface "enp9s0f3"
Port "br0"
Interface "br0"
type: internal
Does your host belong to any group, ie, has it sent any joins?
Laxmikanta:- Yes, TG2 sending join message.
Do you have a single port in the bridge?
Laxmikanta:- Two port in the bridge.
And are you receiving joins on that port, or only multicast messages
without any joins?
Laxmikanta:- I am able to see the multicast message and query message in
wirashark.
Thanks & Regards,
