Bug Description
[Impact]
It is currently not possible to use Multicast IGMP snooping with OVN in Ubuntu Focal and Hirsute.
[Test Plan]
1. Execute the gate tests for the neutron-
2. Enable IGMP snooping and have instances join a multicast group and validate that packets forward and check for RBAC errors.
[Regression Potential]
This is a very small patch that adds a static RBAC rule that ovn-northd writes into the database. The patch has already been available in the upstream branches since February 2021, we have also landed several similar patches upstream which have previously been made available to Focal through point release updates.
[Original Bug Description]
Hi,
I've tested this on both 20.03 and 20.06.
Looking into ovn-architectur
It states that once RBAC is enabled, ovn-controllers will have access to some of the tables and that is hardcoded within OVN.
That means once RBAC is enabled, IGMP_Group table is out of reach for ovn-controllers and will cause the following issue:
