Hi, I'm interested in the Linux kernel's support for per-flow IPv4 ECMP (i.e. consistent path selection based on a hash of the connection tuple). I'd been led to believe[1] that this depended on the route cache, which was removed in 3.6.
However, I tested a route with multiple next hops on a 3.10 and 3.13 kernel, and ECMP was per-flow! Obviously I'm pleased that this was the case, but I'd like to understand why this is supported, and whether I can rely on it in future. Could anyone give me a little clarification on whether this is now supported by some means other than the route cache, and whether that support is intended to be continued?
