[openstack-dev] Merge multiple OVS bridges ?
Hi Currently in Neutron the integration bridge (br-int) and other bridges configured over each physical nic (e.g. br-eth0, br-eth1 etc) are being configured in Compute and Network nodes. What is the logic behind or advantages having 2 OVS bridges in the physical host? Can we have only one bridge for each physical NIC, similar to what linux bridge setup has. And configure/modify the flows such that VLAN conversion is appropriately setup for ingress and egress traffic within the single bridge. Thus also eliminating the veth pairs used to connect the bridges together. Is this a feasible proposal, and can it be worked on? -- Regards Gopi Krishna ___ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev

Are the below observations on Havana?

Are the below observations on Havana? My observations are w.r.t. Grizzly, but I didnot see any changes in Havana reg. the same. -- Regards Gopi Krishna ___ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev

Sure, please file a blueprint and submit a patch for this, I would review this for sure! :) There are optimizations underway around this area. For example, we're looking at possibly collapsing the individual Linuxbridge and OVS agents into a single agent. In the context of ML2, this makes sense. I've thought a bit about collapsing the bridges from two to one and this is something which seems quite doable frankly.
