BIRD would be nicer to work with but the last time I checked it wasn't playing nice with ECMP on FreeBSD. Regardless, if OSPF is an option you can pursue that will definitely work. *[image: userimage]Scott Larson[image: los angeles] Lead Systems Administrator[image: wdlogo] [image: linkedin] [image: facebook] [image: twitter] [image: instagram] T 310 823 8238 <310%20823%208238%20x1106> | M 310 904 8818 <310%20904%208818>* On Mon, Feb 13, 2017 at 4:23 PM, Olivier Cochard-Labb=C3=A9 wrote: > 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: Fir= st > 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 rout= e > entry and never try the second entry :-( > > Is there something else to enable (like RSS?) for having a real ECMP flow > based router ? > > Thanks, > _______________________________________________ > freebsd-net@freebsd.org mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-net > To unsubscribe, send any mail to "freebsd-net-unsubscribe@freebsd.org" >
