Description of problem: This is the same bug as in Fedora: https://bugzilla.redhat.com/show_bug.cgi?id=734697 In Fedora, this bug has been fixed. Also in Debian: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=556974 Doing multipath routing with IPv4 works fine, but it doesn't with IPv6: # ip -6 route add default nexthop via 2001:470:25:94::1 weight 1 nexthop via 2001:41e0:ff00:47::1 weight 1 Error: an IP address is expected rather than "2001:470:25:94::1" Note that the Debian bug doesn't specify it, but the problem happens even if you only specify one path: # ip -6 route add default nexthop via 2001:470:25:94::1 weight 1 This should be equivalent to the same command without the "nexthop": # ip -6 route add default via 2001:470:25:94::1 weight 1 Error: an IP address is expected rather than "2001:470:25:94::1" Again, this works perfectly fine with IPv4. How reproducible: 100% Steps to Reproduce: 1. Make sure your network is IPv6 enabled 2. Try adding a multipath IPv6 route (it doesn't have to have several "nexthop", one is enough to trigger the bug) Actual results: Below error output: Error: an IP address is expected rather than "2001:470:25:94::1" Expected results: A working IPv6 multipath route.
