Here is a patch adapted from ospfd patch of "Tue Sep 25 11:25:41 2007 UTC" (the one of version 1.52 of kroute.c): << Last missing piece in the equal cost multipath support for ospfd. Send all possible nexthops to the parent process and correctly sync the RIB, FIB and kernel routing table. Based on initial work by pyr@. OK pyr@ norby@ PS: don't forget that you need to enable multipath support via a sysctl >> It seems to solve my problem but not "perfectly". When starting ospf6d with the best link between 2 hosts down, fib contains 2 other routes comme from 2 other hosts (these 2 routes have equal cost). When the link came UP, these 2 routes are removed and replaced by the best route; that's alright. Next when the link goes down, the 2 alternative routes are well added in fib but the precedent best route is still in the fib (I see it with route -n -v show |grep TargetIP). May be an important point: TargetIP is an IPv6 on lo1. I can't find why; if you have any idea... I have a test network so I can make test easily...
