This configuration can cause asymmetric routing. Response for request going from LB1 to a backend server could come back to LB2. LB2 does not have any state for this response and hence will drop the packet. Without syncing all the TCP state it can lead to unpredictable results. To sync all state clustering support is needed.

For example: 2 or more haproxy with the same config, the same set of backend servers. Each one doing backend tests separately. And all of them handle requests. It is normally working. Regards Dominik 18 sie 2015 01:42 "Rudra Rugge" <[email protected]<mailto:[email protected]>> napisal(a): Active-active mode for loadbalancer in opencontrail requires clustering support for haproxy. Clustering of haproxy is currently not available and hence active-active cannot be supported today with haproxy.
