Description Assaf Muller 2017-03-17 23:09:38 UTC
OVN L3 is currently a single point of failure and it should be highly available.

Comment 3 Miguel Angel Ajo 2017-04-24 13:15:30 UTC
Discussing up with the community

And talking about limitations of the planned approach to do L3 HA Active/Standby, which are also present on VRRP or other protocols.

Comment 4 Assaf Muller 2017-04-24 13:28:12 UTC
This will require OVS 2.8, pushed to OSP 13.

Comment 5 Miguel Angel Ajo 2017-07-17 15:50:27 UTC
ovn-core patches merged, now we need to work on the networking-ovn side.

Comment 7 Nir Yechiel 2017-10-03 15:00:29 UTC
An idea we just discussed was extending the northbound database with a simple boolean on the Gateway_Chassis table to reflect if it's the current master or not.  That information is already available through the southbound database by examining the Port_Binding table, but doing something in the northbound db would be a usability improvement.

One catch is that the current db schema allows you to reference a single Gateway_Chassis for multiple gateways, so maybe putting the column on Gateway_Chassis doesn't work.  Another option could be a new column on Logical_Router_Port that references a single gateway_chassis row to indicate which is the current master.
