Hi, Second question. When i read this: https://techwiki.juniper.net/Documentation/Contrail/Contrail_Controller_Feature_Guide/Administration/30_Managing_Service_Chaining#ECMP_Load_Balancing_in_the_Service_Chain [Rudra] This is simple load balancing of traffic based on ECMP. Based on a hash - the flows are distributed across service virtual machines. There is no proxying of traffic. I guess that active-active service instance should work. But: after changing LbaaS to active-active (this line: https://github.com/Juniper/contrail-controller/blob/R2.20/src/config/svc-monitor/svc_monitor/services/loadbalancer/drivers/ha_proxy/driver.py#L102) One of vrouter agent's dies on assert: https://github.com/Juniper/contrail-controller/blob/R2.20/src/vnsw/agent/pkt/flow_table.cc#L1295 contrail-vrouter-agent: controller/src/vnsw/agent/pkt/flow_table.cc:1295: bool FlowEntry::SetRpfNH(FlowTable*, const AgentRoute*): Assertion `l3_flow_ == true' failed. [Rudra] Active-active in service VM service chain is not the same as active-active in LBAAS. LBAAS requires TCP state syncing because LBAAS is acting as a proxy. Setting LBAAS to active-active is not supported. We are looking at adding this support with other LBAAS vendors. Regards, Rudra Maybe i don't understand this corectly. Could you help me with this? --- Regards Dominik 2015-08-18 7:06 GMT+02:00 Dominik Mostowiec <[email protected]>: > Why? > For example: 2 or more haproxy with the same config, the same set of backend > servers. > Each one doing backend tests separately.
