Keepalived Direct Routing Configuration. Direct Routing configuration of Keepalived is similar in configuration with NAT. In the following example, Keepalived is configured to provide load balancing for a group of real servers running HTTP on port 80. To configure Direct Routing, change the lb_kind parameter to DR.
lb_algo: The algorythm that will be used for balancing. Our example uses round-robin (rr). lb_kind: How traffic will be routed. We’re using Direct Routing (DR) to allow our backend to respond directly to clients. persistence_timeout: If persistent connections are required, this sets the timeout to expire the connection.
Direct routing allows real servers to process and route packets directly to a requesting user rather than passing outgoing packets through the LVS router. Direct routing requires that the real servers be physically connected to a network segment with the LVS router and be able to process and direct outgoing packets as well.

Traditional or L2 DSR Direct Server Return also known as: › Direct Routing › SwitchBack (Foundry/Brocade) › nPath (F5) General packet flow: › clients send requests to a Virtual IP (VIP) served by the LoadBalancer › LB determines real server to forward the request to › LB performs MAC Address Translation (MAT), 12/5/2016 · HA routing protocols (such HSRP, VRRF, GLBP, etc.) on two routers to allow Local servers to use multiple routers that act as a single virtual router, maintaining connectivity even if the primary router fails, because the secondary router will take over and become active, or run an internal routing protocol such as iBGP which will learn routes …
