IGMP snooping/query support in Openvswitch
As I know, Openvswitch is a L2 virtual switch that currently does not support IGMP snooping/query. (This has been confirmed from Openvswitch mailing list.)
We are running 2 VM (VM-A and VM-B) under same VLAN on the same OpenStack compute node (Grizzly version) with Openvswitch (v1.9.0). Both VM-A and VM-B are in same security group. Theoretically, if only VM-A has joined the multicast group, VM-B can also receive this multicast traffic even VM-B has not join the group (since there’s no IGMP snooping/query implementation in Openvswitch)
However in our experiment, VM-B would not receive the multicast traffic joined by VM-A. The effect like Openvswitch has already supported IGMP snooping/query. Is there anything we have missed?
Security groups maybe?
Hi darragh, both VM-A and VM-B are in same security group
@tcheung - any solution for this? I'm looking for the same answer.
