I can't reproduce this on 9.0-CURRENT, where radix_mpath code is almost the same as in 8. Can you please provide more information: full ifconfig output, more data in routing table, may be a more precise reproduction recipe? -- Totus tuus, Glebius.
Try this: sysctl -w net.inet.flowtable.enable=0 ifconfig em0 10.11.11.175/24 ifconfig em0 alias 10.20.20.1/24 route add -net 10.20.20.0/24 10.11.11.1 -weight 2 ping -c1 10.20.20.100 Kind regards, Ingo Flaschberger
