Mathieu, now I'm getting curious, is it possible to combine Linuxbridge and OVS VXLAN Nodes in the same cloud?
I thought this does not work as Linuxbridge-vxlan uses multicast for instances broad- and multicasts (e.g. an arp request), while ovs-vxlan only does unicast? At least one can specify a vxlan_group, which is a mulitcast address, for linuxbridge vxlan. Or is multicasting prohibited by l2_pop driver and the vxlan_group attribute is not applicable in this case? -- Andreas (irc: scheuran) On Mon, 2015-03-23 at 14:49 +0100, Mathieu Rohon wrote: > Hi romil, > > > I think the main purpose of this DB field is to maintain the > compatibility in dataplane between OVS and LinuxBridge which, by > default, don't use the same UDP port for VXLAN. > > It might be useful for a cloud admin which wants to run some nodes > with LB and some others with OVS. > > > I feel like your patch proposal will enable this scenario if the > tunnel_update() RPC message gets updated with the UDP port too. > > > > Mathieu > > > On Mon, Mar 23, 2015 at 11:40 AM, Romil Gupta <[email protected]> > wrote: > Hello everyone, > > > There is regarding the following bug: > https://bugs.launchpad.net/neutron/+bug/1373359 > > > May I know what is the significance of having the 'udp_port' > field in the 'ml2_vxlan_endpoints' table in Neutron DB, Do we > have any plans in future that we could use this field for > synchronization or any other purpose instead of simply keeping > it in the DB. > > > The following patchset will fix the bug mentioned above, > https://review.openstack.org/#/c/153891/ > > > But the question still remains the same.
