Hi, I'm testing FreeBSD ECMP behavior by adding "options RADIX_MPATH" to my kernel configuration (11-stable). Now I can configure two identical routes toward 2 different next-hop: First step achieved :-) But it uses only the first entry and never uses the second one. I've tried to shutdown the first next-hop router (then no more arp-reply from this next-hop): But the ECMP FreeBSD router sticks to its first route entry and never try the second entry :-( Is there something else to enable (like RSS?) for having a real ECMP flow based router ? Thanks,
